摘　　要：针对粉煤气化高一氧化碳制合成氨变换装置,设计采用一级等温变换炉控制变换温度,二级绝热变换炉来副产过热蒸汽,三级等温变换炉尽可能降低温度,达到深度变换的要求。该工艺不仅使高浓度的一氧化碳变换反应在较温和的工艺条件下进行,而且能副产高品质中压过热蒸汽。Aiming at the CO shift unit of high concentration carbon monoxide to synthetic ammonia in pulverized coal gasification,a first-stage isothermal converter is designed to control the conversion temperature,a second-stage adiabatic converter to by-produce superheated steam,and a third-stage isothermal converter to reduce the temperature as much as possible to meet the requirement of deep conversion.The process not only makes the high concentration CO shift reaction occur under mild process conditions,but also can by-produce high quality superheated steam.
