摘要
中—低—低变换工艺具有操作简便、蒸汽耗量低、触媒使用寿命长的特点。将中变串低变工艺改为中—低—低工艺后。
The medium low low temperature shift process has the features of simple operation, low steam consumption and long catalyst service life. With the change from the process of medium temperature shift in series with low temperature shift to the medium low low temperature shift process, the need for increase in ammonia output can be met.
