Thread Content
This post was last edited by Kongfen Zhulong on 2011-3-29 at 13:22. The demand for industrial CO is currently growing rapidly; please share your insights on the application of membrane separation technology in the CO extraction industry. This was suggested by a netizen before!
The advantages of membrane separation are low equipment investment and small floor space required. However, compared with pressure swing adsorption for CO purification, the CO product obtained through membrane separation has lower purity and yield, and it is also suitable only for a limited range of feed gases.
The advantage of membrane separation for CO recovery is low pressure loss (CO is on the retentate side), low energy consumption, and the possibility of combining it with other separation methods depending on the gas composition
I have been working with membrane separation for a few years; it is used to purify CO. The investment required depends on the purity level of CO that needs to be achieved. If the requirements regarding both the purity of CO and the yield are not very high, then membrane separation is a more cost-effective option from an investment and operational perspective. However, if a higher level of purity is required, then membrane separation becomes less economical. So, the investment decision is mainly based on the requirements for the product gas CO.
The separation coefficient of CO using membrane separation is not high, so only rough separation is possible; I have no experience with specific industrial applications in this area
PSA requires significant investment, has many power-driven components, but its operation is quite simple with a high degree of automation
What is the approximate investment ratio of membrane separation compared to PSA? What is the range of feed gases suitable for membrane separation?
A PSA carbon monoxide purification unit with a capacity of 10,000 Nm3/h typically requires an investment of ten to twenty million yuan. And the membranes of corresponding size are around three to five million. Save more than half.
Each has its advantages; the appropriate process route is determined based on the specific process conditions. Make use of strengths and avoid weaknesses
I’ve never been in this industry before; it’s quite unfamiliar to me, so I came to take a look. I’m not aware of how membrane contamination occurs in this field Is cleaning necessary? Study* study!*
