PROCESS AND APPARATUS FOR THE GASIFICATION OF SOLIDS

摘要

In the gasification of carbonaceous solids with oxygen and/or steam, the solids are at least partly converted to CO and H2 in a first process step (10). In a second process step (20), a stream containing water then is separated from the product mixture obtained. This stream containing water finally is subjected to water purification in a third process step (30). This water purification is effected such that three streams (31, 36, 37) with different degrees of purity are obtained, at least one of which is recirculated in the process.
