ABSTRACT:
A plant for producing, eg ammonia or methanol by catalytic synthesis at superatmospheric temperature and pressure comprises a vessel equipped internally with all the high-temperature units required for the synthesis, namely means for heating synthesis gas to synthesis inlet temperature, admitting it to the catalyst, withdrawing it and cooling it. Preferably all the high-pressure units are also inside the vessel. The plant makes possible extremely high outputs of product, such as 8000 metric tons per day.
