Title: METHOD FOR PRODUCING SYNGAS, AS WELL AS SYNGAS COOLING ASSEMBLY AND USE
Abstract:
The invention relates to a method for producing syngas (SG) in a two-pressure-level ammonia plant (1) having a first synthesis section (10a) operated as a continuous flow at a first relatively lower high-pressure level (hp1) and having a second synthesis section (10b) operated as a cycle at a second relatively higher high-pressure level (hp2), wherein the syngas in the first synthesis section, is cooled to a pressure level below the first high-pressure level, downstream of an OT reactor (10a1) of the first synthesis section by means of a coolant, wherein the coolant is provided at a pressure level below the first high-pressure level by means of a medium-pressure steam generator (13), or wherein the cooling occurs by means of the medium-pressure steam generator. This provides a process that is advantageous in many respects. The invention also relates to a syngas cooling assembly (10) for heat discharge out of the syngas in a two-pressure-level ammonia plant (1) of this type. The invention further relates to the use of at least one system component for providing or for using the coolant.
