METHOD FOR REMOVING AMMONIA FROM A METHANOL CONTAINING STREAM |
摘要 |
A stream of liquid methanol containing ammonia and other species is sent to the top of a countercurrent stripping column. The stream is stripped with a flow of ambient-temperature nitrogen or another inert gas. The column can be packed with random dumped packing. The overhead vapor contains ammonia and the liquid exiting the column has a reduced amount of ammonia. Removing ammonia can reduce or prevent fouling or corrosion caused by ammonia (and other compounds).
