Use new methods to optimize energy efficiency of hydrogen compressors

摘要

Hydrogen (H2) is a key to efficient operation of refinery de-sulfurization units (DSUs). Process H2, both pure and recycled from DSUs, must be compressed to pressures up to 85 kg/cm~2. Centrifugal compressors and reciprocating compressors are used depending on the flow and pressure requirements of the process. Reciprocating compressors are often used for low to medium flow conditions under a wide range of pressure rates.
