Luoyang Wohong Condensation Membrane Separation Device, a manufacturer of triple oil and gas recovery equipment for gas stations

The third oil and gas recovery process at gas stations involves the discharge of oil and gas from the breathing valve of the storage tank due to temperature differences and pressure changes between day and night. This part of the exhaust gas cannot be completely eliminated through the oil unloading and refueling process, and requires end of pipe treatment devices. The condensation membrane separation device of Luoyang Wohong is a mature technology route in the industry, adopting the combination process of "condensation+membrane separation". The equipment is assembled and debugged before leaving the factory, and can be put into operation by simply connecting the power supply and pipeline on site.

Process principle: combination of 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 specified in GB20952-2020. The overall oil and gas recovery rate can reach over 95%.

Design and Technical Characteristics of Skid Assembly

Quick installation: The lever mounted structure integrates each unit on a steel base, and can be operated on site by simply connecting the power and gas circuits. The installation cycle is short, the footprint is small, and it is suitable for gas station site conditions.

Controllable operating costs: The equipment is powered by electricity and does not consume natural gas, with a unit energy consumption of approximately 0.43kW/m ³. andactivated charcoalCompared to adsorption, membrane separation does not produce secondary pollutants such as waste activated carbon and does not require solid waste treatment.

Safe and reliable: The process operates without open flames and has good applicability in explosion-proof areas of 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.

The company has relevant technology patents and the ability to integrate and pry, and can match equipment specifications based on parameters such as daily refueling volume, tank capacity, and oil and gas production at gas stations. Before selection, on-site working condition testing can be arranged to customize the plan based on actual parameters.
