Abstract
A process for the simultaneous production of methanol synthesis gas and ammonia synthesis gas proceeds from the crude gas of a coal gasification, which initially is subjected to a H.sub.2 S-washing at low temperatures. Then follows a splitting of the desulfurized gas into two partial streams, of which one partial stream is led directly into the CO.sub.2 -washing which serves for production of the methanol-synthesis gas. Another partial stream is in contrast initially subjected to a conversion. From the converted gas then a partial stream is branched off which is provided for the production of ammonia-synthesis gas, whereas the remainder of the converted gas is led into the CO.sub.2 -washing serving for the production of the methanol-synthesis gas. The partial straem serving for the production of the ammonia-synthesis gas is treated to a separate CO.sub.2 -washing, in which simultaneously the so-called purge gas from the ammonia-synthesis is led in. The H.sub.2 S-washing and the CO.sub.2 -washings are conneced with each other by a common washing agent circulation.
