Condensation+membrane separation treatment equipment

Condensation+membrane separation treatment equipmentIntroduction

1. Boost condensation control

Using Antoine et al. to calculate the saturated vapor pressure of organic gas molecules based on the composition of oil and gas, and calculating the phase transition conditions at different temperatures for the main organic gas composition of C3~C12 gas types, controlling the condensation time at different pressures, and separating the remaining liquefied products and allowing them to re-enter the membrane separation system for separation.

2. Membrane separation process

After the condensation process, the residual oil and gas are discharged into the membrane separation system. The molecular separation technology is achieved by utilizing the small amount of residual oil and gas in the oil and gas, which have different permeability of small and large molecules. The separated molecules enter the atmospheric and vacuum distillation device to bring the gas pressure to atmospheric pressure, completing the phase change liquefaction of the mixed gas and achieving complete recovery of oil and gas, thereby ensuring ultra-low emission concentration of exhaust gas.

RP3000-LM2 condensation+membrane separation is suitable for use in oil stations with an annual sales volume of less than 3000 tons, with low electricity consumption. The upper limit of emission value is 10g/m3.

RP3000-LM5 condensation+membrane separation is suitable for use in oil stations with an annual sales volume of less than 5000 tons, and has fast tank pressure control efficiency. The upper limit of emissions is less than 10g/m3.

RP3000-LM8 condensation+membrane separation is suitable for use in oil stations with an annual sales volume of less than 8000 tons, and has fast tank pressure control efficiency. The upper limit of emissions is less than 10g/m3.

The new gas membrane separation technology is the third-generation gas membrane separation technology for volatile organic gases and air separation. Compared with the first generation gas permeation membrane technology, the second generation adsorption separation technology, and the current gas molecular screening separation technology, the new third-generation gas membrane separation technology has the following incomparable advantages:

1. Firstly, with the improvement of separation efficiency of the third-generation gas membrane separation technology compared to the previous two generations of gas membranes, the treatment of VOCs waste gas can be more efficient, with lower energy consumption, and long-term stable compliance of exhaust emissions after waste gas treatment. And its separation process is cleaner and more environmentally friendly, without generating secondary pollution, the equipment runs smoothly, and occupies a smaller area.

2. Secondly, the equipment has a long service life. Compared with adsorption oil and gas separation, membrane separation does not have adsorption saturation desorption processes or processes such as replacing adsorbents. Therefore, as long as it does not come into contact with substances that are highly damaging to the membrane, it generally will not malfunction. Under normal circumstances, the service life of the membrane is over 5 years.

3. Once again, its safety is high. Compared with the adsorption oil and gas separation closed system, the membrane separation system is an open system, and there are no hidden safety hazards caused by phase change heat of oil and gas during operation, nor are there any related dangers caused by sudden changes in system pressure.

4. Another issue is that membrane separation requires fewer auxiliary equipment and lower investment.

In short, membrane separation technology is a system that integrates recovery and emission standards, and is currently the world's most efficient, reasonable, and low-cost oil and gas recovery technology.
