METHOD OF DISTRIBUTION OF STEAM BETWEEN STEAM TURBINES OPERATING AT COUNTERPRESSURE IN PRODUCTION OF AMMONIA Russian patent published in 2004 - IPC

FIELD: power engineering, chemical industry.

SUBSTANCE: invention can be used for production of ammonia from hydrocarbon gases. According to proposed method of distribution of steam between steam turbines operating at counterpressure in production of ammonia from hydrocarbon gases, summary consumption of mean pressure steam by steam turbines operating at counterpressure G_st is maintained at level whose value is determined from equation G_st=G_cd+G_d+G_wa+G_h where G_cd is consumption of low-pressure steam for cleaning gas from CO₂ and distillation of process condensate; G_d is consumption of low-pressure steam for deaeration of feed water; G_wa is consumption of low-pressure steam for by water-ammonia cooling plant; G_h is consumption of low pressure steam for heating apparatuses, pipelines and other purposes.

EFFECT: optimization of production and distribution of steam at production of ammonia, reduced cost of generation of high-pressure steam, reduced consumption of feed water.
