Method of cooling hot synthesis gas and synthesis gas cooler.

摘要

The invention is related to a method of cooling a hot synthesis gas containing solids under conditions which permit removal of solids from solid gas. The hot synthesis gas is passing at initial high temperature downwardly through a first contacting zone, thereby passing a film of cooling liquid on walls of said first contacting zone that is cooling said synthesis gas; the so cooled synthesis gas is passing a body of aqueous cooling liquid in a second contacting zone; the further cooled synthesis gas containing a decreased content of solid particles is withdrawn upwardly from said second contacting zone through a annular third contacting zone to a vapor-liquid desengagement zone with an arcuated path terminating the gas stream with a substantial downward component of velocity whereby the non-gaseous components contained therein are downwardly directed toward said body of aqueous cooled liquid thereby forming a synthesis gas stream of lower solids content; said synthesis gas stream of lower solids content is passing again upwardly. Said cooled synthesis gas will be recovered.
