Who knows how much a membrane for a hydrogen recovery system costs? The processing capacity is within 20,000 cubic meters of process gas. Thank you!
At such a large scale, ours number over 2,000 units. It’s quite expensive anyway – the membranes, along with all the other pipeline equipment, are all costly
The recovery of 20,000 cubic meters of hydrogen is on a daily basis, right? There are two processes for recovery using membrane technology. Abroad, compressors typically use membranes with a pressure of 6 to 8 kilograms, which results in lower operating costs and a longer lifespan for the membranes; the downside is however the need for a large number of membranes, leading to higher initial investment costs. Many facilities in China currently use a pressure of 15 kilograms for processing; this results in energy consumption that is more than twice as high as that with lower pressures, since hydrogen is difficult to compress. However, the use of fewer membranes reduces their lifespan, while the lower investment leads to faster returns. The cost of the membranes is approximately 30 million yuan
The maximum processing capacity is 20,000 cubic meters per hour. It’s not very big, is it?
It’s not very large, but it is quite large. Is it necessary to adjust the flow rate? I’m not sure what you use the hydrogen for – what level of purity is required? The investment in such membranes amounts to hundreds of millions
The driving force behind membrane separation technology is the partial pressure difference, and pressure is a crucial parameter for determining investment costs. Membrane separation technology is now quite mature. To obtain products with good cost-performance ratios, it’s sufficient to contact several companies and conduct a bidding process (it is recommended not to rely solely on a few distributors of the same manufacturer). Domestic manufacturers: Tianbang Membrane Technology **Engineering Research Center Co., Ltd.; American membrane agents: Dalian Maitek Technology Development Co., Ltd ； Sichuan Dakota ； Cipruxin, etc. French membrane distributor: Dalian Ouke Membrane Technology Engineering Co., Ltd. Japanese membrane distributor: Dalian Tianbang Membrane
The cost of using membrane recovery is a bit high, right?
Yes, PSA requires a large amount of space and involves significant investment
20,000 cubic meters per hour – that’s not that much. We use membranes from Dalian Ouke and Air Liquide; the designed gas processing capacity is over 9,800 cubic meters per hour, with a hydrogen recovery rate of over 78% and a hydrogen purity of over 90%
It’s estimated that the owner’s investment of over 10 million should be sufficient to cover it
