Three stage oil and gas recovery equipment at gas stations, Luoyang Wohong compression condensation membrane separation device

The three times of oil and gas recovery at gas stations is a key link in the treatment of the end of storage tanks. The breathing valve discharge of oil and gas from oil storage tanks due to temperature differences and pressure changes between day and night cannot be completely eliminated through unloading and refueling processes, requiring specialized end treatment devices. The compression condensation membrane separation device of Luoyang Wohong is a mature technology route in the current industry.

Process principle: combination of compression condensation and membrane separation

The device consists of a compression condensation unit and a membrane separation unit. Oil and gas come out of the breather valve of the storage tank, are pressurized by the compressor, and enter the condensing unit. The temperature is controlled between zero and minus ten degrees Celsius, and most of the heavy hydrocarbon components above C5 are liquefied into liquid gasoline, which flows back to the storage tank.

The uncondensed exhaust gas enters the membrane separation unit.gas separation membraneUtilizing the difference in permeation rate between oil and gas molecules and air molecules in membrane materials - oil and gas molecules preferentially pass through the membrane layer to form concentrated gas, which is then sent back to the compressor inlet for cyclic processing; Air is intercepted and discharged in compliance with standards. The entire system forms a closed-loop loop, and the emission concentration can stably meet the emission limit requirements.

Skincard design, ready to use

The equipment adopts a modular structure, with the compressor, condenser, membrane components, and control system all integrated on a steel base. They are assembled and debugged before leaving the factory, and can be put into operation on site by simply connecting the power supply and piping. Small footprint, suitable for gas station site conditions. If relocation is required in the later stage, it can be lifted as a whole and the equipment can be reused.

Controllable operating costs, safe and reliable

Powered by electricity, without consuming natural gas, with a unit energy consumption of approximately 0.43kW/m ³. The process has no open flames and is suitable for use in explosion-proof areas at gas stations. The system automatically starts and stops based on the pressure of the oil tank, working when there is gas and waiting when there is no gas, without the need for manual supervision.
