在线热备气化炉经济性论证分析

Economical Demonstration Analysis of Online Hot Standby Gasifier

甲醇中心气化装置原有七台气化炉,新增第八套气化炉于3月7日正式试车后正常运行。根据公司生产要求,气化装置需要保证六台气化炉在线运行,保证每天甲醇合成所需的合成气供应,为此,气化装置将原来的"六开一检修"运行模式转换为"六开一备一检修",保证在运行气化炉有突发情况时能够及时投用备用炉,进而确保生产的平稳。但是长期热备一台气化炉需要消耗大量的燃料气或碳四燃料,造成生产成本增加,为了确定是否在线热备一台气化炉,对热备气化炉进行经济性论证分析。

The original gasification device of methanol center gasifier,the new eight sets of gasifier in the March 7 after the normal operation of the normal test.According to the company＇s production requirements,gasification devices need to ensure that six gasifier on-line operation to ensure that the daily synthesis of synthetic gas required for methanol synthesis,for this purpose,the gasification device will be the original ＂six open an overhaul＂ operating mode is converted to ＂six Open a spare maintenance＂to ensure that the operation of the gasifier in a sudden situation can be timely use of standby furnaces,and thus ensure the smooth production.However,a long-term hot standby gasifier needs to consume a large amount of fuel gas or carbon four fuels,resulting in increased production costs,in order to determine whether a hot standby gasifier,hot standby gasification furnace economic demonstration analysis.
