The Reason Analysis And The Countermeasure From Synthetic Tower Pressure Rise

Xinjiang Korla Tarim large chemical fertilizer project in synthetic ammonia produc tion capacity of 450000 T/A, with Denmark Topsoe company S a 300 radial ammonia production process is one of the largest chemical fertilizer plant, a single set of dome-stic production capacity at present.In order to reduce energy consumption,improve thea-mmonia yield,reached the design capacity.The analysis of the causes of ammonia synth-etic tower of elevated pressure from various aspects,the unfavorable factors to eliminat e adopt effective methods,control of pressure,increase ammonia output.This paper made a comprehensive analysis of the theory on various factors inducing synthesis tower pressure,and combined with the production practice,put forward spec-ific measures for reduction.Combining theory with practice.Through a series of validati on means such as ammonia compressor export condenser online cleaning;synthesis towe r Import Export heat exchanger leakage causes and disposal technology;liquid ammoni a tank to the non condensable gas ammonia cooler,low pressure relief gas flow for the best value confirmation,improve device production capacity to ensure the smooth operation of the device.At the same time,also for domestic and similar devices similar prob-lems,provides a disposal plan, has a very high practical significance.In this paper,the quantization of the scheme and measures, embodied in the execut able and maneuverability. Step is clear, after several failed repeatedly,confirm the exac data after repeated. As is very scientific and reasonable to the compressor speed, contr ol of anti surge valves. The paper relates to the economic benefits is remarkable, probl em solving, enterprises can save 190000000 of annual economic loss, which is equival ent to a large chemical plant benefit sum.
