Abstract： In order to make full use of resources， the membrane separation technology was used to recover hydrogen from PSA tail gas of catalytic reforming unit. The coupling of new membrane separation device and the existing PSA process for recovering hydrogen from PSA tail gas achieved considerable economic benefits， at the same time， hydrogen with 99.9% purity was produced. The recovery of hydrogen was about 2.3 kt/a， which not only alleviated the shortage of hydrogen resources in the plant， but also increased the efficiency by 23 million Yuan. The calorific value of the fuel gas pipe network was increased， the energy consumption and nitrogen oxides emission of other hydrogen production units were reduced. In this paper， the principle， process and calibration of membrane separation were introduced， and the treatment measures were put forward according to the problems in production operation.
