油氣污染物主要由碳?xì)涞葥]發(fā)性有機(jī)物組成，許多成分具有致癌作用，并且在空氣中會(huì)轉(zhuǎn)化生成臭氧（O3）和細(xì)顆粒物（PM2.5），是造成光化學(xué)煙霧、灰霾等大氣污染問題的重要原因。同時(shí)，油氣污染物屬于易燃易爆氣體，遇火極易發(fā)生爆炸或火災(zāi)事故。通過油氣污染治理，可以將油氣進(jìn)行回收和集中處理，進(jìn)一步轉(zhuǎn)變?yōu)槠?，有利于?jié)約資源和保護(hù)環(huán)境。

　　Oil and gas pollutants are mainly composed of volatile organic compounds such as hydrocarbons, many of which have carcinogenic effects and can be converted into ozone (O3) and fine particulate matter (PM2.5) in the air. They are an important cause of atmospheric pollution problems such as photochemical smog and haze. Meanwhile, oil and gas pollutants belong to flammable and explosive gases, which are highly prone to explosions or fire accidents when exposed to fire. Through the treatment of oil and gas pollution, oil and gas can be recovered and centrally processed, further converted into gasoline, which is beneficial for conserving resources and protecting the environment.

　　1.卸油過程監(jiān)測(cè)

　　1. Monitoring of oil unloading process

　　01

　　01

　　在油罐車卸油時(shí)，油氣回收系統(tǒng)會(huì)將油罐車內(nèi)的油氣通過氣相管道輸送回加油站的地下油罐。在線監(jiān)測(cè)系統(tǒng)中的傳感器會(huì)監(jiān)測(cè)氣相管道內(nèi)的壓力、流量和油氣濃度。例如，根據(jù)伯努利方程，通過監(jiān)測(cè)壓力差和流量可以判斷油氣是否正常回收。如果壓力差過小或者流量異常，可能是卸油油氣回收裝置出現(xiàn)故障。

　　When unloading oil from a tanker truck, the oil and gas recovery system will transport the oil and gas inside the tanker truck back to the underground oil tank at the gas station through gas-phase pipelines. The sensors in the online monitoring system will monitor the pressure, flow rate, and oil and gas concentration inside the gas-phase pipeline. For example, according to the Bernoulli equation, monitoring pressure difference and flow rate can determine whether oil and gas are being recovered normally. If the pressure difference is too small or the flow rate is abnormal, it may be a malfunction of the oil and gas recovery device.

　　2.加油過程監(jiān)測(cè)

　　2. Monitoring of refueling process

　　02

　　當(dāng)汽車加油時(shí)，加油槍的出油動(dòng)作會(huì)同時(shí)觸發(fā)油氣回收。油氣通過回收通道被收集到地下油罐或者油氣回收處理設(shè)備中。系統(tǒng)通過流量傳感器監(jiān)測(cè)加油量，同時(shí)利用壓力和濃度傳感器監(jiān)測(cè)回收油氣的狀態(tài)。例如，按照一定的油氣回收比例（如 1:1 的氣液比），當(dāng)加油量為 10 升時(shí)，理論上應(yīng)該回收 10 升左右的油氣。如果實(shí)際回收量與理論值偏差過大，系統(tǒng)就會(huì)發(fā)出警報(bào)。

　　When refueling a car, the dispensing action of the fuel gun will simultaneously trigger the recovery of oil and gas. Oil and gas are collected into underground oil tanks or oil and gas recovery and treatment equipment through recovery channels. The system monitors the refueling volume through flow sensors, while using pressure and concentration sensors to monitor the status of recovered oil and gas. For example, according to a certain oil and gas recovery ratio (such as a 1:1 gas-liquid ratio), when the refueling volume is 10 liters, theoretically around 10 liters of oil and gas should be recovered. If the actual recycling amount deviates too much from the theoretical value, the system will issue an alarm.

　　During the oil storage stage, the main focus is on monitoring the pressure and changes in oil and gas concentration inside the underground oil tank. Due to factors such as temperature changes, the pressure and concentration of oil and gas inside the oil tank may change. By monitoring these parameters, it is possible to promptly detect whether the sealing performance of the oil tank is good. If the oil tank is not sealed properly, oil and gas will leak, causing a decrease in oil and gas concentration and abnormal pressure.

　　油氣回收在線監(jiān)控哪些數(shù)據(jù)

　　What data is monitored online for oil and gas recovery

　　1.加油槍監(jiān)測(cè)數(shù)據(jù)

　　1. Monitoring data of fuel gun

　　氣液比

　　Gas-liquid ratio

　　定義與計(jì)算：氣液比是指加油時(shí)回收的油氣體積與所加燃油體積之比。通過在加油槍和油氣回收管道分別安裝流量傳感器，實(shí)時(shí)獲取油氣流量和燃油流量，然后計(jì)算氣液比。例如，若加油槍燃油流速為30L/min，油氣回收管道油氣流量為36L/min（假設(shè)此時(shí)油氣已換算為與燃油相同的體積單位），則氣液比為36÷30 = 1.2。

　　Definition and Calculation: Gas liquid ratio refers to the ratio of the volume of recovered oil and gas to the volume of fuel added during refueling. By installing flow sensors on the refueling gun and oil and gas recovery pipeline respectively, real-time oil and gas flow rates and fuel flow rates can be obtained, and then the gas-liquid ratio can be calculated. For example, if the fuel flow rate of the refueling gun is 30L/min and the oil and gas flow rate of the oil and gas recovery pipeline is 36L/min (assuming that the oil and gas have been converted to the same volume unit as the fuel), then the gas-liquid ratio is 36 ÷ 30=1.2.

　　重要性與標(biāo)準(zhǔn)范圍：氣液比是衡量油氣回收效率的關(guān)鍵指標(biāo)。正常情況下，其范圍一般在1.0 - 1.2之間。如果氣液比過高，可能是油氣回收系統(tǒng)吸力過大，會(huì)對(duì)汽車油箱等造成損害；如果氣液比過低，則說明油氣回收不完全，大量油氣會(huì)泄漏到大氣中，造成環(huán)境污染和安全隱患。

　　Importance and standard range: Gas liquid ratio is a key indicator for measuring the efficiency of oil and gas recovery. Under normal circumstances, its range is generally between 1.0-1.2. If the gas-liquid ratio is too high, it may be due to excessive suction in the oil and gas recovery system, which can cause damage to the car's fuel tank, etc; If the gas-liquid ratio is too low, it indicates incomplete oil and gas recovery, and a large amount of oil and gas will leak into the atmosphere, causing environmental pollution and safety hazards.

　　油氣流速和油氣流量

　　Oil and gas flow rate and oil and gas flow rate

　　油氣流速：油氣流速是指油氣在油氣回收管道中的流動(dòng)速度，單位通常為米/秒（m/s）。它與油氣流量密切相關(guān)，并且受到管道直徑、油氣回收泵的功率等因素的影響。例如，在直徑較小的油氣回收管道中，為了保證一定的油氣流量，油氣流速可能會(huì)相對(duì)較高。

　　Oil and gas flow velocity: Oil and gas flow velocity refers to the flow velocity of oil and gas in the oil and gas recovery pipeline, usually measured in meters per second (m/s). It is closely related to the flow rate of oil and gas, and is influenced by factors such as pipeline diameter and power of oil and gas recovery pumps. For example, in oil and gas recovery pipelines with smaller diameters, in order to ensure a certain oil and gas flow rate, the oil and gas flow velocity may be relatively high.

　　油氣流量：油氣流量是指單位時(shí)間內(nèi)通過油氣回收管道的油氣體積，單位為立方米/分鐘（m?/min）或升/分鐘（L/min）。準(zhǔn)確測(cè)量油氣流量對(duì)于評(píng)估油氣回收系統(tǒng)的運(yùn)行效率至關(guān)重要。在實(shí)際監(jiān)測(cè)中，通過安裝在油氣回收管道上的流量傳感器來獲取油氣流量數(shù)據(jù)，并且要根據(jù)加油槍的出油情況來判斷油氣流量是否正常。例如，當(dāng)加油槍出油流量為一定值時(shí)，油氣流量應(yīng)根據(jù)氣液比要求保持在相應(yīng)的合理范圍內(nèi)。

　　Oil and gas flow rate: Oil and gas flow rate refers to the volume of oil and gas passing through the oil and gas recovery pipeline per unit time, measured in cubic meters per minute (m ?/min) or liters per minute (L/min). Accurately measuring oil and gas flow rate is crucial for evaluating the operational efficiency of oil and gas recovery systems. In actual monitoring, oil and gas flow data is obtained through flow sensors installed on the oil and gas recovery pipeline, and whether the oil and gas flow is normal is judged based on the oil discharge of the refueling gun. For example, when the oil flow rate of the refueling gun is a certain value, the oil and gas flow rate should be maintained within a reasonable range according to the gas-liquid ratio requirements.

　　燃油流速和燃油流量

　　Fuel flow rate and fuel flow rate

　　燃油流速：燃油流速是指燃油從加油槍流出的速度，單位為升/分鐘（L/min）。它主要取決于加油槍的型號(hào)和內(nèi)部結(jié)構(gòu)。不同型號(hào)的加油槍燃油流速不同，燃油流速的穩(wěn)定與否也能反映加油槍的工作狀態(tài)是否正常。

　　Fuel flow rate: Fuel flow rate refers to the speed at which fuel flows out of the fuel nozzle, measured in liters per minute (L/min). It mainly depends on the model and internal structure of the fuel gun. The fuel flow rate of different models of refueling guns varies, and the stability of the fuel flow rate can also reflect whether the refueling gun is working properly.

　　燃油流量：燃油流量是指在一定時(shí)間內(nèi)從加油槍流出的燃油總體積，單位為升（L）。通過對(duì)燃油流量的監(jiān)測(cè)，可以準(zhǔn)確計(jì)算出加油的總量，用于加油站的油品銷售統(tǒng)計(jì)等工作。同時(shí)，燃油流量也是計(jì)算氣液比的重要參數(shù)之一，與油氣流量配合使用，來評(píng)估油氣回收系統(tǒng)的性能。

　　Fuel flow rate: Fuel flow rate refers to the total volume of fuel flowing out of the fuel nozzle within a certain period of time, measured in liters (L). By monitoring the fuel flow rate, the total amount of fuel added can be accurately calculated, which can be used for fuel sales statistics at gas stations. Meanwhile, fuel flow rate is also one of the important parameters for calculating gas-liquid ratio, which is used in conjunction with oil and gas flow rate to evaluate the performance of the oil and gas recovery system.

　　回收油氣濃度

　　Recovery of oil and gas concentration

　　定義與測(cè)量方法：回收油氣濃度是指回收的油氣中油氣成分所占的比例，通常用體積分?jǐn)?shù)（%）或質(zhì)量分?jǐn)?shù)（g/m?）來表示。可以通過氣體檢測(cè)儀器，如氣相色譜儀或紅外吸收式氣體檢測(cè)儀等來測(cè)量回收油氣濃度。這些儀器能夠?qū)τ蜌庵械闹饕煞郑ㄈ缣細(xì)浠衔铮┻M(jìn)行分析，從而得出準(zhǔn)確的濃度數(shù)據(jù)。

　　Definition and measurement method: The concentration of recovered oil and gas refers to the proportion of oil and gas components in the recovered oil and gas, usually expressed as volume fraction (%) or mass fraction (g/m ?). The concentration of recovered oil and gas can be measured using gas detection instruments such as gas chromatographs or infrared absorption gas detectors. These instruments can analyze the main components in oil and gas, such as hydrocarbons, to obtain accurate concentration data.

　　作用與影響因素：回收油氣濃度對(duì)于評(píng)估后處理裝置（如活性炭吸附裝置、冷凝裝置等）的負(fù)荷和處理效果很重要。如果回收油氣濃度過高，可能會(huì)超出后處理裝置的處理能力，導(dǎo)致處理不完全，使部分油氣排放到大氣中。其濃度受到多種因素的影響，如加油量、汽車油箱內(nèi)原有油氣含量、油氣回收系統(tǒng)的密封性等。

　　Function and influencing factors: The concentration of recovered oil and gas is important for evaluating the load and treatment effect of post-treatment devices (such as activated carbon adsorption devices, condensation devices, etc.). If the concentration of recovered oil and gas is too high, it may exceed the processing capacity of the post-treatment device, resulting in incomplete treatment and partial emission of oil and gas into the atmosphere. Its concentration is influenced by various factors, such as the amount of fuel added, the existing oil and gas content in the car's fuel tank, and the sealing of the oil and gas recovery system.

　　回收油氣溫度

　　Recovery oil and gas temperature

　　影響因素與變化范圍：回收油氣溫度主要受到環(huán)境溫度、油品溫度以及油氣回收過程中的能量轉(zhuǎn)換等因素的影響。一般情況下，回收油氣溫度在環(huán)境溫度到油品溫度之間波動(dòng)。例如，在夏季高溫環(huán)境下，回收油氣溫度可能會(huì)相對(duì)較高；而在冬季，溫度則會(huì)較低。其溫度范圍可能在 - 20℃到60℃左右，具體取決于加油站所處的地理位置和季節(jié)。

　　Influencing factors and range of variation: The temperature of recovered oil and gas is mainly affected by environmental temperature, oil temperature, and energy conversion during the oil and gas recovery process. In general, the temperature of recovered oil and gas fluctuates between ambient temperature and oil temperature. For example, in high temperature environments during summer, the temperature of recovered oil and gas may be relatively high; In winter, the temperature will be lower. The temperature range may be around -20 ℃ to 60 ℃, depending on the geographical location and season of the gas station.

　　對(duì)系統(tǒng)的影響：回收油氣溫度會(huì)影響油氣的物理性質(zhì)，如密度和體積，進(jìn)而影響油氣流量和油氣回收效率。較高的溫度會(huì)使油氣體積膨脹，可能導(dǎo)致油氣回收管道內(nèi)壓力升高；同時(shí)，溫度也會(huì)對(duì)后處理裝置的運(yùn)行產(chǎn)生影響，如在活性炭吸附過程中，溫度過高可能會(huì)降低吸附效果。

　　The impact on the system: The temperature of the recovered oil and gas will affect the physical properties of the oil and gas, such as density and volume, which in turn will affect the oil and gas flow rate and oil and gas recovery efficiency. Higher temperatures can cause the volume of oil and gas to expand, which may lead to an increase in pressure inside the oil and gas recovery pipeline; At the same time, temperature can also affect the operation of the post-treatment device. For example, during the adsorption process of activated carbon, excessive temperature may reduce the adsorption effect.

　　液阻

　　Liquid resistance

　　定義與測(cè)量方式：液阻是指油氣回收管道內(nèi)由于液體（如油品或冷凝水）積聚對(duì)油氣流動(dòng)產(chǎn)生的阻力。通常通過在油氣回收管道中設(shè)置壓力傳感器，在一定的油氣流量下（如30L/min），測(cè)量管道兩端的壓力差來判斷液阻大小。例如，當(dāng)壓力差超過規(guī)定值（如4.5kPa）時(shí)，判定為液阻過大。

　　Definition and measurement method: Liquid resistance refers to the resistance caused by the accumulation of liquid (such as oil or condensate) in the oil and gas recovery pipeline to the flow of oil and gas. Usually, pressure sensors are installed in the oil and gas recovery pipeline to measure the pressure difference at both ends of the pipeline at a certain oil and gas flow rate (such as 30L/min) to determine the size of the liquid resistance. For example, when the pressure difference exceeds the specified value (such as 4.5kPa), it is judged as excessive liquid resistance.

　　危害與解決措施：液阻過大會(huì)阻礙油氣的正常回收，導(dǎo)致油氣不能順利回到油罐，從而造成油氣泄漏。如果發(fā)現(xiàn)液阻過大，需要檢查油氣回收管道是否存在積水、油品積聚或其他堵塞物，及時(shí)清理管道以降低液阻，保證油氣回收系統(tǒng)的正常運(yùn)行。

　　Hazards and solutions: Excessive liquid resistance can hinder the normal recovery of oil and gas, resulting in the inability of oil and gas to return to the oil tank smoothly, leading to oil and gas leakage. If excessive liquid resistance is found, it is necessary to check whether there is water accumulation, oil accumulation or other blockages in the oil and gas recovery pipeline, and clean the pipeline in a timely manner to reduce liquid resistance and ensure the normal operation of the oil and gas recovery system.

　　加油槍狀態(tài)數(shù)據(jù)

　　Fuel gun status data

　　監(jiān)測(cè)加油槍的關(guān)?；騿⒂脮r(shí)間對(duì)于加油站的運(yùn)營(yíng)管理和安全很重要?？梢詼?zhǔn)確記錄每一次加油的開始時(shí)間和結(jié)束時(shí)間，從而統(tǒng)計(jì)加油的時(shí)長(zhǎng)、頻率等信息。同時(shí)，這也有助于發(fā)現(xiàn)異常的加油操作，比如加油槍長(zhǎng)時(shí)間未關(guān)閉等情況。

　　Monitoring the shutdown or activation time of fuel guns is crucial for the operational management and safety of gas stations. It is possible to accurately record the start and end times of each refueling, in order to calculate the duration, frequency, and other information of refueling. At the same time, this also helps to detect abnormal refueling operations, such as situations where the refueling gun has not been turned off for a long time.

　　2.環(huán)境數(shù)據(jù)

　　2. Environmental data

　　油罐壓力

　　Oil tank pressure

　　數(shù)據(jù)重要性：油罐壓力是油氣回收系統(tǒng)中的關(guān)鍵環(huán)境數(shù)據(jù)。油罐壓力的變化直接反映了油罐內(nèi)油氣狀態(tài)和整個(gè)油氣回收系統(tǒng)的平衡情況。如果油罐壓力過高，可能會(huì)導(dǎo)致油罐破裂，引發(fā)嚴(yán)重的油品泄漏和安全事故；而壓力過低則可能使油罐被吸癟，損壞油罐結(jié)構(gòu)。

　　Data importance: Tank pressure is a critical environmental data in oil and gas recovery systems. The change in oil tank pressure directly reflects the state of oil and gas inside the tank and the balance of the entire oil and gas recovery system. If the pressure in the oil tank is too high, it may cause the tank to rupture, leading to serious oil leakage and safety accidents; If the pressure is too low, it may cause the oil tank to collapse and damage its structure.

　　正常范圍及影響因素：正常情況下，油罐壓力一般在 - 0.3kPa到6kPa之間波動(dòng)。其壓力受到油品進(jìn)出量、溫度變化、油氣回收速度等多種因素的影響。例如，在卸油過程中，隨著油品快速注入油罐，罐內(nèi)油氣被壓縮，壓力會(huì)升高；當(dāng)外界溫度升高時(shí)，罐內(nèi)油氣膨脹，壓力也會(huì)增大。

　　Normal range and influencing factors: Under normal circumstances, the pressure of the oil tank generally fluctuates between -0.3kPa and 6kPa. Its pressure is influenced by various factors such as the inflow and outflow of oil products, temperature changes, and the speed of oil and gas recovery. For example, during the unloading process, as the oil is rapidly injected into the tank, the oil and gas inside the tank are compressed, and the pressure will increase; When the external temperature rises, the oil and gas inside the tank expand, and the pressure also increases.

　　監(jiān)控目的：通過在線監(jiān)控油罐壓力，可以實(shí)時(shí)掌握油罐的安全狀態(tài)。當(dāng)壓力接近或超出設(shè)定的安全范圍時(shí)，系統(tǒng)能夠及時(shí)發(fā)出警報(bào)，提醒工作人員采取措施，如調(diào)整油氣回收速度、檢查油罐通氣系統(tǒng)等，以確保油罐的安全和油氣回收系統(tǒng)的正常運(yùn)行。

　　Monitoring purpose: By monitoring the pressure of the oil tank online, the safety status of the tank can be monitored in real time. When the pressure approaches or exceeds the set safety range, the system can issue an alarm in a timely manner to remind the staff to take measures, such as adjusting the oil and gas recovery speed, checking the oil tank ventilation system, etc., to ensure the safety of the oil tank and the normal operation of the oil and gas recovery system.

　　液阻壓力

　　Liquid resistance pressure

　　數(shù)據(jù)重要性：液阻壓力是指油氣回收管道內(nèi)由于液體（如油品或冷凝水）積聚對(duì)油氣流動(dòng)產(chǎn)生的阻力所對(duì)應(yīng)的壓力。液阻壓力過大意味著油氣回收管道可能存在堵塞問題，這會(huì)阻礙油氣的正?；厥?，導(dǎo)致油氣泄漏。

　　Data importance: Liquid resistance pressure refers to the pressure corresponding to the resistance caused by the accumulation of liquid (such as oil or condensate) in the oil and gas recovery pipeline to the flow of oil and gas. Excessive hydraulic resistance pressure means that there may be blockage in the oil and gas recovery pipeline, which can hinder the normal recovery of oil and gas and lead to oil and gas leakage.

　　測(cè)量及判斷標(biāo)準(zhǔn)：通常在油氣回收管道中設(shè)置壓力傳感器，在一定的油氣流量下（如30L/min），測(cè)量管道兩端的壓力差來判斷液阻壓力是否正常。當(dāng)這個(gè)壓力差超過規(guī)定值（如4.5kPa）時(shí)，判定為液阻過大。

　　Measurement and judgment criteria: Pressure sensors are usually installed in oil and gas recovery pipelines to measure the pressure difference at both ends of the pipeline at a certain oil and gas flow rate (such as 30L/min) to determine whether the hydraulic resistance pressure is normal. When the pressure difference exceeds the specified value (such as 4.5kPa), it is judged as excessive liquid resistance.

　　監(jiān)控目的：對(duì)液阻壓力進(jìn)行在線監(jiān)控，可以及時(shí)發(fā)現(xiàn)油氣回收管道的堵塞情況。一旦液阻壓力異常升高，工作人員能夠及時(shí)清理管道內(nèi)的積液，檢查管道的排水設(shè)施，確保油氣回收管道的暢通，提高油氣回收效率，減少油氣泄漏風(fēng)險(xiǎn)。

　　Monitoring purpose: Online monitoring of hydraulic resistance pressure can promptly detect blockages in oil and gas recovery pipelines. Once the hydraulic resistance pressure rises abnormally, the staff can promptly clean the accumulated liquid in the pipeline, inspect the drainage facilities of the pipeline, ensure the smooth flow of the oil and gas recovery pipeline, improve the efficiency of oil and gas recovery, and reduce the risk of oil and gas leakage.

　　油氣空間（油罐內(nèi)）

　　Oil and gas space (inside the oil tank)

　　數(shù)據(jù)重要性：油罐內(nèi)的油氣空間大小影響著油氣的壓力、濃度等參數(shù)。它與油品的存儲(chǔ)量、油罐的大小以及油氣的產(chǎn)生和回收情況密切相關(guān)。了解油氣空間有助于準(zhǔn)確評(píng)估油罐內(nèi)的油氣狀態(tài)和潛在的安全風(fēng)險(xiǎn)。

　　Data importance: The size of the oil and gas space inside the oil tank affects parameters such as pressure and concentration of the oil and gas. It is closely related to the storage capacity of oil products, the size of oil tanks, and the production and recovery of oil and gas. Understanding the oil and gas space helps to accurately assess the oil and gas status and potential safety risks inside the oil tank.

　　計(jì)算與影響因素：油氣空間可以通過油罐的總體積減去油品體積來計(jì)算。其大小受到油品的進(jìn)出、溫度變化引起的體積變化等因素的影響。例如，在高溫環(huán)境下，油品體積膨脹，油氣空間相對(duì)減?。欢谛队瓦^程中，隨著油品的增加，油氣空間也會(huì)相應(yīng)減小。

　　Calculation and influencing factors: The oil and gas space can be calculated by subtracting the volume of oil products from the total volume of the oil tank. Its size is affected by factors such as the inflow and outflow of oil, volume changes caused by temperature changes, etc. For example, in high temperature environments, the volume of oil expands and the oil and gas space relatively decreases; During the unloading process, as the amount of oil increases, the oil and gas space will also decrease accordingly.

　　監(jiān)控目的：通過監(jiān)控油氣空間，工作人員可以更好地掌握油罐內(nèi)的油氣動(dòng)態(tài)。結(jié)合其他環(huán)境數(shù)據(jù)（如油罐壓力、油氣濃度），可以提前預(yù)測(cè)可能出現(xiàn)的安全問題，如油氣空間過小可能導(dǎo)致壓力急劇上升，從而采取相應(yīng)的措施，如控制卸油速度、加強(qiáng)油氣回收等。

　　Monitoring purpose: By monitoring the oil and gas space, staff can better grasp the oil and gas dynamics inside the oil tank. By combining other environmental data such as tank pressure and oil and gas concentration, potential safety issues can be predicted in advance. For example, a small oil and gas space may lead to a sharp increase in pressure, and corresponding measures can be taken, such as controlling the unloading speed and strengthening oil and gas recovery.

　　卸油區(qū)油氣濃度

　　Oil and gas concentration in the unloading area

　　數(shù)據(jù)重要性：卸油區(qū)油氣濃度是反映卸油過程中油氣泄漏情況的重要指標(biāo)。高濃度的油氣在卸油區(qū)聚集，不僅會(huì)對(duì)環(huán)境造成污染，還存在較大的安全隱患，因?yàn)橛蜌庥龅交鹪春苋菀滓l(fā)火災(zāi)或爆炸。

　　Data importance: The concentration of oil and gas in the unloading area is an important indicator reflecting the leakage of oil and gas during the unloading process. High concentrations of oil and gas accumulate in the unloading area, which not only pollutes the environment but also poses significant safety hazards, as oil and gas can easily cause fires or explosions when exposed to a source of fire.

　　正常范圍及測(cè)量方法：卸油區(qū)油氣濃度一般應(yīng)低于當(dāng)?shù)丨h(huán)保和安全規(guī)定的標(biāo)準(zhǔn)，例如，油氣濃度應(yīng)控制在爆炸下限的一定比例以下（通常為25%左右）?？梢允褂脷怏w檢測(cè)儀器，如可燃?xì)怏w檢測(cè)儀來實(shí)時(shí)測(cè)量卸油區(qū)的油氣濃度。

　　Normal range and measurement method: The oil and gas concentration in the unloading area should generally be lower than the local environmental and safety regulations. For example, the oil and gas concentration should be controlled below a certain proportion of the lower explosive limit (usually around 25%). Gas detection instruments, such as combustible gas detectors, can be used to measure the concentration of oil and gas in the unloading area in real time.

　　監(jiān)控目的：對(duì)卸油區(qū)油氣濃度進(jìn)行在線監(jiān)控，能夠及時(shí)發(fā)現(xiàn)卸油過程中的油氣泄漏情況。當(dāng)濃度超過安全閾值時(shí)，系統(tǒng)會(huì)發(fā)出警報(bào)，工作人員可以立即停止卸油操作，檢查卸油設(shè)備和油氣回收系統(tǒng)的密封性，采取通風(fēng)等措施降低油氣濃度，確保卸油區(qū)的安全。

　　Monitoring purpose: To monitor the oil and gas concentration in the unloading area online, and to promptly detect oil and gas leaks during the unloading process. When the concentration exceeds the safety threshold, the system will issue an alarm, and the staff can immediately stop the oil unloading operation, check the sealing of the oil unloading equipment and oil and gas recovery system, take ventilation and other measures to reduce the oil and gas concentration, and ensure the safety of the oil unloading area.

　　后處理裝置排放濃度

　　Emission concentration of post-treatment device

　　數(shù)據(jù)重要性：后處理裝置排放濃度直接反映了油氣回收后處理的效果。如果后處理裝置排放濃度過高，說明油氣處理不完全，會(huì)導(dǎo)致大量油氣排放到大氣中，對(duì)環(huán)境造成污染，違反環(huán)保法規(guī)。

　　Data importance: The emission concentration of the post-treatment device directly reflects the effectiveness of oil and gas recovery post-treatment. If the emission concentration of the post-treatment device is too high, it indicates incomplete oil and gas treatment, which will lead to a large amount of oil and gas emissions into the atmosphere, causing pollution to the environment and violating environmental regulations.

　　標(biāo)準(zhǔn)及檢測(cè)手段：后處理裝置排放濃度應(yīng)符合國(guó)家和地方的環(huán)保排放標(biāo)準(zhǔn)，例如，排放口的油氣濃度一般要求低于25g/m?。可以通過安裝在排放口的氣體檢測(cè)儀器，如催化燃燒式檢測(cè)儀等進(jìn)行檢測(cè)。

　　Standards and testing methods: The emission concentration of the post-treatment device should comply with national and local environmental emission standards. For example, the oil and gas concentration at the discharge outlet is generally required to be less than 25g/m?. It can be detected through gas detection instruments installed at the exhaust outlet, such as catalytic combustion detectors.

　　監(jiān)控目的：在線監(jiān)控后處理裝置排放濃度，有助于及時(shí)發(fā)現(xiàn)后處理裝置的故障或處理效果不佳的情況。當(dāng)排放濃度超標(biāo)時(shí)，能夠提醒工作人員對(duì)后處理裝置進(jìn)行維護(hù)、調(diào)整或更換，確保油氣經(jīng)過處理后達(dá)標(biāo)排放，減少對(duì)大氣環(huán)境的污染。

　　Monitoring purpose: Online monitoring of the emission concentration of the post-treatment device helps to timely detect faults or poor treatment effects of the post-treatment device. When the emission concentration exceeds the standard, it can remind the staff to maintain, adjust or replace the post-treatment device to ensure that the oil and gas are discharged in compliance after treatment, reducing pollution to the atmospheric environment.

　　油氣溫度

　　Oil and gas temperature

　　數(shù)據(jù)重要性：油氣溫度會(huì)影響油氣的物理性質(zhì)，如密度、體積和蒸氣壓等。這些物理性質(zhì)的變化又會(huì)對(duì)油罐壓力、油氣流量和油氣回收效率等產(chǎn)生影響。例如，較高的油氣溫度會(huì)使油氣體積膨脹，可能導(dǎo)致油罐壓力升高，同時(shí)也會(huì)影響油氣回收管道內(nèi)的壓力和流量。

　　Data importance: Oil and gas temperature can affect the physical properties of oil and gas, such as density, volume, and vapor pressure. These changes in physical properties will also have an impact on oil tank pressure, oil and gas flow rate, and oil and gas recovery efficiency. For example, higher oil and gas temperatures can cause the volume of oil and gas to expand, which may lead to an increase in tank pressure and also affect the pressure and flow rate inside the oil and gas recovery pipeline.

　　變化范圍及影響因素：油氣溫度的變化范圍通常與環(huán)境溫度和油品溫度有關(guān)，一般在 - 20℃到60℃左右。其主要受季節(jié)變化、油品溫度、太陽(yáng)輻射等因素的影響。在夏季，油氣溫度可能較高；而在冬季，溫度則較低。

　　Change range and influencing factors: The change range of oil and gas temperature is usually related to the ambient temperature and oil temperature, generally around -20 ℃ to 60 ℃. It is mainly affected by factors such as seasonal changes, oil temperature, and solar radiation. In summer, oil and gas temperatures may be higher; In winter, the temperature is lower.

　　監(jiān)控目的：通過在線監(jiān)控油氣溫度，可以更好地理解油氣的狀態(tài)變化。結(jié)合其他環(huán)境數(shù)據(jù)（如油罐壓力、油氣流量），可以提前預(yù)測(cè)和預(yù)防可能出現(xiàn)的問題，如在高溫環(huán)境下提前采取措施防止油罐壓力過高，或者在低溫環(huán)境下注意防止油氣中的某些成分凝結(jié)而堵塞管道。

　　Monitoring purpose: By monitoring the temperature of oil and gas online, we can better understand the changes in the state of oil and gas. By combining other environmental data such as tank pressure and oil and gas flow rate, possible problems can be predicted and prevented in advance, such as taking measures to prevent excessive tank pressure in high-temperature environments, or paying attention to preventing certain components in oil and gas from condensing and blocking pipelines in low-temperature environments.
