煤炭气化技术我国中型氨厂现有间歇式气化炉400多台。小型氨厂数千台,用于制氨。改造的方向是连续气化。水煤浆加压气化(以德士古法为典型代表)具有能耗较低,污染少,对煤种适应性广等特点,粗煤气中CO+H_2含量高,适用于合成氨、甲醇生产。目前,除已投产的鲁南化肥厂和即将投产的渭河化肥厂外,“九五”期间一些大中型氨厂的改造,拟采用水煤浆气化工艺。
Coal gasification technology China’s medium-sized ammonia plant has more than 400 intermittent gasifiers. Thousands of small ammonia plants are used for ammonia production. The direction of transformation is continuous gasification. The coal gas slurry pressure gasification (typically represented by Texaco’s method) has the characteristics of low energy consumption, less pollution, wide adaptability to coal types, high CO+H2 content in crude gas, and is suitable for the production of ammonia and methanol. . At present, in addition to the production of Lunan Fertilizer Plant and the upcoming production of the Luohe Chemical Fertilizer Plant, during the “Ninth Five-Year Plan” period, the transformation of large and medium-sized ammonia plants is planned to use the coal-water slurry gasification process.
