Process for recycling and purifying condensate from a hydrocarbon or alcohol synthesis process.

摘要

This invention relates to a process of recycling condensate (16) from a hydrocarbon or alcohol synthesis (10), wherein the condensate (16) comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture (22) comprising CH4 and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH4, and steam are separately recovered as a gaseous stream (30) from the remaining purified water (26). The recovered CH4-containing gaseous stream (30) may be used in synthesis, gas (CO/H2) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons (12).
