Abstract
A system comprising a hydrogen source and a nitrogen source. A hydrogen compression unit compresses hydrogen from the hydrogen source. An ammonia synthesis unit fluidly coupled to the hydrogen compression unit and to the nitrogen source compresses a hydrogen and nitrogen blend which is delivered to the ammonia synthesis unit. In use, a seal gas feed line delivers compressed hydrogen to dry gas seals of the hydrogen compressor and a separation gas feed line delivers nitrogen to the at least one dry gas seal. The ammonia synthesis unit is fluidly coupled to vents of the dry gas seals, to receive and process compressed hydrogen from the hydrogen compression unit, nitrogen from the nitrogen source and gas venting from the dry gas seals.
