Abstract: The compression train (13) for a dehydrogenation plant (1) comprises a driver (36) and a single centrifugal compressor (35) drivingly coupled to the driver. The centrifugal compressor comprises a single casing and a plurality of compressor sections (39.1, 39.2, 39.3) inside said casing (37). Each compressor section comprises at least one impeller (40.1, 40.2) arranged for rotation in the casing (37). The compressor (35) is adapted to compress a mixture containing propane, propylene and hydrogen, having a molecular weight between 20 and 35 g/mol, from a suction pressure between about 0.2 barA and about 1.5 barA to a delivery pressure between about 11 barA and about 20 barA, with a volumetric flowrate comprised between about 120,000 m3/h and about 950,000 m3/h.

Abstract: A compression unit for ammonia comprising a multi-stage compressor, including a first set of compressor stages adapted to compress a syngas containing hydrogen and nitrogen; and a second set of compressor stages adapted to compress a refrigerant of a refrigerant circuit. Described herein is also an ammonia production system including the ammonia compression unit and a method.

Abstract: The ammonia production plant includes a feed gas compression section, a process air compression section, a syngas compression section and a refrigerant compression section. At least two of these compression sections are combined together forming a combined compression train driven by a single driver.
