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 of less than or equal to one bar and obtained from a front end purification unit/cold box unit.
