Ammonia synthesis from gases produced by coal gasification - improved by producing medium-pressure steam to reduce costs

摘要

Medium - pressure steam (20 - 80 atm.) is produced by the coal - gasification and partial oxidation process, whereby costs of installation and operation are reduced compared with the conventional high - pressure installations. The steam is used in turbines driving pumps, compressors, etc. A part of steam is reacted with CO to produce H2.
