LuoyangWohong PetrochemicalThe tertiary oil and gas recovery equipment developed and manufactured by Equipment Co., Ltd. is mainly used for the treatment of the end of gas tank breathing oil and gas, and for the recovery of hydrocarbon oil and gas spilled during the breathing process of the storage tank, effectively control the pressure of the storage tank, reduce the loss of oil volatilization, and meet the requirements of environmental protection control of oil and gas emissions. The equipment adopts the mature condensation film coupling process of Wohong, and takes the independent organic gas vapor film module as the core separation unit. The whole device is integrated with skid assembly, compact structure and small floor area. The assembly and performance debugging of the whole machine are completed before leaving the factory. The site can be put into operation only by docking the pipeline and power supply, and the installation and construction period is short.

When the pressure in the oil storage tank rises to the set threshold, the three-time oil and gas recovery equipment of Wo Hong starts automatically to extract the oil, gas and air mixture in the storage tank. The mixed oil and gas first enters the compression and condensation unit for cooling and liquefaction, and most of the hydrocarbon oil and gas is condensed into liquid gasoline, which is returned to the oil storage tank after gas-liquid separation. The uncondensed low-concentration oil and gas mixture is sent to the Wo Hong organic vapor membrane module. Driven by the pressure difference on both sides of the membrane, hydrocarbon oil and gas molecules preferentially selectively penetrate the membrane layer, enrich on the permeation side to form high-concentration oil and gas, and circulate it back to the storage tank. The air component is difficult to penetrate the membrane body, and the trapped clean tail gas meets the discharge standard. The system monitors the pressure in the tank in real time, and the pressure drops to the lower limit value, automatically stops and waits for standby, and runs automatically in the whole process.

The perfect explosion-proof and temperature control protection system of Wo Hong's third oil and gas recovery equipment is specially designed for the explosion-proof environment of gas stations, avoiding the safety risks brought by high-temperature hot spots, and can operate stably and continuously all day long. Complete membrane separation unitactivated charcoalSuch as consumables, do not need frequent replacement of adsorption materials, there is no safety hazard caused by activated carbon regeneration, the operation process does not produce waste residue secondary pollutants, daily operation and maintenance workload is greatly reduced. The equipment is equipped with intelligent PLC automatic control system, which has the functions of one-key start and stop, remote transmission of operation data, fault self-diagnosis and alarm, which is convenient for remote monitoring and management of on-site personnel.

Relying on the research and development platform of Henan Oil and Gas Recovery Engineering Technology Research Center, Wohong can customize the equipment processing capacity according to the size of the gas station, the volume of the storage tank and the working conditions of the oil products, and adapt to the new gas station and the technical renovation and upgrading project of the original oil and gas system. The use of Wo Hong condensation film coupling process, high oil and gas recovery efficiency, can effectively reduce the volatile loss of oil products, the recovery of liquid gasoline directly back to the tank for use, in the realization of environmental protection standards discharge at the same time to create material recovery income. Wo Hong provides full-chain services from working condition survey, process design, equipment manufacturing, on-site installation guidance to later operation and maintenance, ensuring the long-term stable and reliable operation of the whole set of tertiary oil and gas recovery system.
