| Abstract: | This paper presents the pressurized medium-low-low shift process in ammonia plant in Wujin Chemical Co.Ltd.Operation condition of M.T.shift process at the third stage at ambient pressure before revamping and pressurized medium-low-low shift precess after revamping are compared.With the application of pressurized medium-low-low shift process,CO content at shift gas exit is reduced to less than 1% and steam consumption per ton ammonia is cut down to 0.124 t,achieving good economic benefit. |
