Oil and gas testing instruments serve thousands of households

The number of cars in our country continues to increase. Cars may gradually become popular in every household as electric cars. Gas stations will become an important facility in people's lives. When oil is refueled, emissions of oil and gas will bring health to the atmosphere and people. As a result, threats, therefore, oil and gas recovery technologies and equipment that can suppress pollution and reduce safety risks are becoming increasingly popular. Oil and gas detection instruments are the key to oil and gas recovery technology.

Oil and gas emissions prompted the introduction of standards

According to the provisions of the national standard GB20952-2007 "Emission Standards for Gasoline Pollutants at Gas Stations", municipalities of Beijing, Tianjin and Hebei Province shall implement the control standards for oil and gas unloading, oil and gas storage and refueling on May 1, 2008; The cities of the Delta and the Pearl River Delta should implement the control standards for oil and gas unloading, oil storage and refueling on January 1, 2010; other city-based cities should implement the unloading oil and gas emission control standards on January 1, 2012, 1 On the 1st of each month, oil and gas refueling control standards were implemented. At present, the national gas stations have fully adopted the oil and gas recovery system, and the time point for reaching the discharge standard is close. However, the main parameters of the oil and gas recovery system, such as liquid resistance, airtightness, and gas-liquid ratio, can be tested according to the national standard to ensure its quality and safety. There are few instrumental products. Why is this? On this issue, Instrument Information Network editor interviewed Sun Zuofu, deputy chief engineer of Qingdao Laoshan Applied Technology Institute.

According to Sun Zuofu, the development of oil and gas recovery testing equipment does not present itself with major technical difficulties. However, the construction of the recovery system project for gas stations requires a process. Before that, the market has not yet formed, and inspection requirements have not been generated. In the past, there was a lack of related testing products. However, in the years following the release of the testing standards, significant progress has been made in the construction of recovery system projects for gas stations. The government’s efforts in this area are also increasing, and the detection of oil and gas recovery will become a routine detection indicator. , Such testing products will continue to appear. Thanks to the grasp of demand and the accumulation of technology in the research and development of smoke and smoke products over the years, we should have successfully developed the 7003 type oil and gas recovery multiparameter detector in 2010. In the past three years, we have continuously upgraded and improved our products based on the opinions and feedback of our customers. It has become a mature and practical product and is currently one of the only two products of its kind (the other is Nanjing Dexu's product).

In terms of applications, Sun Zufu said that the pre-production products were mainly used in markets such as Shanghai that pioneered the use of oil and gas recovery systems. Currently, they have been promoted to cities in the country that have already carried out oil and gas recovery testing for gas stations, and the units that use this equipment are mainly environmental monitoring stations. In addition, some third-party testing institutions, mainly oil industry, currently have relatively mature markets such as Beijing and Shanghai, and have regularly tested the gas stations with the Coking 7003 oil-gas recovery multi-parameter detector.

National gas station set up oil and gas recovery system

The "Air Station Air Pollutant Emission Standard" is based on the international advanced method for the control of oil and gas emissions in gasoline storage, transportation, and sales. It also considers the actual conditions of China's gas stations and refers to relevant national pollutant discharge regulations. The technical content stipulates the gasoline gasoline and gas emission limits, control technical requirements, and detection methods at gas stations.

It is understood that the oil and gas recovery system is the collective name for various technical methods and equipment for preventing air quality by preventing the entry of volatile hydrocarbons into the atmosphere during the transportation and distribution of oil. It is an energy-saving and environment-friendly new technology and uses oil and gas recovery technology. Recover oil and gas discharged during the storage, transportation, and handling of oil products, prevent air pollution caused by the volatilization of oil and gas, eliminate potential safety hazards, and increase the utilization of energy. In the application of the oil station can be divided into a primary oil and gas recovery system and secondary oil and gas recovery system.

The transformation of oil and gas recovery in Anhui Suzhou gas station has achieved three oil and gas recovery. The first recovery is when the tanker truck delivered from the oil depot to the petrol station unloads the oil at the petrol station and recovers the oil and gas at the time of unloading the tanker; the second recovery is when the petrol station refuels the car and it will refuel. The oil and gas are sealed and returned to the gas station via the modified fueling gun; the third recovery is the gradual increase of oil and gas at the gas station of the gas station. When it reaches a certain pressure, it is discharged from the original to the atmosphere instead of pressure. With filter membranes, only the air is released into the atmosphere, and the oil and gas are automatically compressed into oil and returned to the tank.

From the Changchun Municipal People's Government, the city decided to collect, seal, store, and centralize the processing of oil and gas pollutants (VOCS) generated by oil storage tanks, gas stations, and tank cars in the administrative area. The existing oil storage and gas stations were Tanker owners will complete their governance tasks by December 31 this year. In the future, Changchun City, newly built, rebuilt or expanded oil storage tanks, gas stations and new oil tankers, should install oil and gas recovery management devices or facilities, and the discharge of oil and gas pollutants should meet the national discharge standards.

Oil and gas testing instruments assist gas station gas recovery

Industry analysts pointed out that the development of oil and gas recovery testing equipment itself does not have great technical difficulties, but the construction of a gas recovery system requires a process. Before that, the market has not yet formed, and inspection needs have not been generated. Therefore, there has been a lack of related inspection products in the past However, in the years following the release of the testing standards, significant progress has been made in the construction of recovery system projects for gas stations. The government’s efforts in this area are also increasing, and the detection of oil and gas recovery will become a routine detection indicator. , Such testing products will continue to appear.

Relevant data show that the number of gas stations in China and the frequency of the use of equipment are also growing rapidly. During the 12th Five-Year Plan, many provinces and autonomous regions have plans to build a large number of gas stations, and these emerging markets will undoubtedly bring the non-oil detection instrument industry To a huge market capacity.
