About hydrogenation and low fraction gas membrane recovery of hydrogen
Thread Content
The low-fractionated gas from the hydrogenation unit contains 70% hydrogen. Can it be recycled using membrane separation technology? What equipment needs to be invested? How much does it cost? How long is the investment payback period required for renovation? The low-gas flow rate is about 300 cubic meters/hour. In addition, can the gas recovered from the gas cabinet be used to recover hydrogen? If any hero finds it useful, please let me know, thank you! ! ! !
The low gas volume is a bit small, and the membrane separation needs to be carefully calculated. The recovered hydrogen can be about 1.6-1.7 million/year, with a membrane system and a compressor. The maintenance fee for compressor operation and membrane replacement may be more than 1 million/year. If the hydrogen content in the gas is high and the flow rate is large, membranes can of course be used for recovery after the pressure is increased.
