| Abstract: | In allusion to the problems existed in the shift section in ammonia synthesis plant of Cangying Chemical-Engineering Investment Company Ltd.,technical reformation measures,in which middle-low-low temperature shift process was changed to fully low temperature shift process in combination with carbon ball carbonation process,have been executed.Author has introduced the technical reformation scheme,and process flow and main equipment after technical reformation,the technical reformation indicates that the steam consume per ton of ammonia is reduced from 660 kg to 390 kg,the economic benefit from saving steam is 2,680,000 Yuan RMB/a;the treatment quantity of semi-water gas is increased from 24,000m3/h to 27,000m3/h,profit 1,800,000 Yuan RMB is increased. |
