Membrane drying of gas feeds to low temperature units |
摘要 |
A process is provided for the low temperature separation of a high purity gas product at lower power requirements by permeating a feed gas stream through a membrane having a water-to-gas-product selectivity of at least about 100, separating water from the gas stream, feeding the partially dried gas stream through a molecular sieve to remove residual water, and supplying the dried gas stream to a low temperature separation unit to separate gas product(s) from the gas stream.
