Three times of oil and gas recovery at gas stations, Luoyang Wohong condensation membrane separation process has high efficiency

The three times of oil and gas recovery at the gas station is the oil and gas discharged from the breathing valve of the oil storage tank. This part of the exhaust gas cannot be completely eliminated through the oil unloading and refueling links, and an end treatment device is required. Luoyang Wo Hong's condensation membrane separation process is a mature technical route.

The equipment employs a combined “condensation + membrane separation” process. The oil and gas are pressurized by the compressor and enter the condensing unit. After cooling, most of the oil and gas are liquefied and returned to the oil storage tank. The uncondensed tail gas enters the membrane module, and by taking advantage of the difference in permeation rate of different gas molecules, the oil and gas molecules preferentially pass through to form concentrated gas and send it back to the front end for circulation treatment, and the air meets the discharge standard. With this technology, the oil and gas treatment rate can reach more than 99%, and the emission concentration can meet the current environmental protection requirements.

The equipment is driven by electricity, there is no combustion process, no open flame, suitable for gas station explosion-proof places. The skid-mounted design integrates each unit on a base, and the assembly and debugging are completed before leaving the factory. The site can be operated only by connecting the power source and the pipeline. The installation period is short and the floor area is small. The control system automatically start and stop according to the oil tank pressure, without manual duty.

Luoyang Wohong's three oil and gas recovery equipment has been shortlisted in the procurement system of large energy companies such as Sinopec and PetroChina, and has practical applications in many provinces. The liquid gasoline recovered by the equipment can be directly reused to achieve the dual effects of emission reduction and income increase.
