Control Of An Ammonia Synthesis Loop At Partial Load

Patent No. EP4054979 (titled "Control Of An Ammonia Synthesis Loop At Partial Load") was filed by Casale on Oct 12, 2020. The application was issued on Nov 29, 2023.

Patent Summary

An ammonia synthesis process comprises a front-end producing make-up synthesis gas, a first compressor raising its pressure, and an ammonia synthesis loop. The loop includes a catalytic converter, a circulator delivering feed gas to the converter via a feed line, a condensation section, and a separation section that splits condensate into liquid ammonia and a gaseous recycle stream returned to the circulator suction. To manage partial load conditions where make-up gas flow is below nominal rates, the process separates a bypass stream from the converter feed line upstream of the converter. This bypass stream is reintroduced at the circulator suction or into the loop downstream of the separation section, enabling flexibility for fluctuating renewable energy inputs.
