Detailed Introduction

Recovering hydrogen from various hydrogen-containing waste gases not only provides the hydrogen needed for industrial production, thereby reducing production costs and increasing economic benefits, but also alleviates environmental pollution caused by waste gas emissions or direct combustion of waste gases. On the one hand, many industries such as petrochemicals, coal chemicals, and fine chemicals require large amounts of hydrogen as a raw material; on the other hand, these industries produce large amounts of hydrogen-containing waste gas during production, which in the past was burned as fuel or directly flared, resulting in the waste of hydrogen resources. In recent years, with the increasing utilization of hydrogen, the demand for hydrogen has increased, and all these factors have encouraged people to adopt processes for recovering hydrogen from various hydrogen-containing industrial gases in factories.
