PROCESS FOR DECREASING OR ELIMINATING UNWANTED HYDROCARBON AND OXYGENATE PRODUCTS CAUSED BY FISHER TROPSCH SYNTHESIS REACTIONS IN A SYNGAS TREATMENT UNIT

摘要

The present invention provides a process for decreasing or eliminating unwanted hydrocarbon and oxygenate products caused by FTS reactions in a syngas treatment unit by utilizing heat exchangers and optionally associated pipes that are substantially fabricated of a material selected from the group consisting of chromium containing alloys and carbon steel for heating up gas streams having a carbon monoxide partial pressure greater than one bar obtained from a front end purification unit/cold box unit.
