The Shift Section is designed to convert a minimum of 95 percent of the carbon monoxide in the syngas to hydrogen. This results in a product gas, after acid gas removal, containing a total of 77.5 MMSCFD hydrogen plus carbon monoxide with an overall hydrogen purity of approximately 96 percent. The design is based on a single operating train as the equipment will have a very high on-stream factor. The particulate-free raw syngas from the Gasification Section is compressed to the design pressure of 810.0 psia prior to processing in the Shift Section. The compressed raw syngas is then mixed with the required volume of superheated steam, heated by exchange with the first shift reactor effluent, and shifted in three stages with interstage cooling. The effluent from the third stage reactor is cooled to 100/sup 0/F for further processing in the Selexol Unit. The hydrogen compression unit compresses a portion of the makeup hydrogen gas stream from the Selexol unit (SRC makeup hydrogen), the recycle hydrogen gas stream from the hydrogen purification unit (HPU), and the bypass recycle hydrogen-rich gas stream from the DEA Unit. The multi-service reciprocating compressor compresses the SRC makeup hydrogen gas stream in the first section with two compressor stages. The recycle and the bypass hydrogen are compressed in the second section with two separate single stages. Design of the compression section is based on three 50% identical trains, two operating and one spare. Each train consists of a triple service reciprocating compressor servicing makeup hydrogen, recycle hydrogen and bypass hydrogen compressions. All three hydrogen streams, after being discharged from the compressors are combined and are ready for processing in the SRC Process Unit.
