WASTE HEAT RECOVERY IN CHEMICAL PROCESS AND PLANT, PARTICULARLY FOR SYNTHESIS OF AMMONIA

摘要

FIELD: chemistry.;SUBSTANCE: invention may be used in chemical industry. The plant, particularly for the synthesis of ammonia, comprises a high-pressure synthesis loop (10) and energy recovering section (50), comprising heat-exchanger (17), designed to provide heat exchange between liquid product (16) from synthesis loop (10) and waste heat stream (18) to deliver the expandable ammonia stream (20), expander (13) for the production of mechanical energy, condenser (22) downstream expander (13) for ammonia condensation.;EFFECT: recovery of heat of syngas effluent from the low-temperature shift reactor.;12 cl, 3 dwg, 1 ex
