GE水煤浆气化工艺的设计优化

Design optimization of GE water-coal slurry gasification process

以某新投产的GE水煤浆气化装置为例,讨论了GE水煤浆气化工艺的设计优化,主要包括高压氮气系统、氧气支管材质及管径、料浆倒料泵的运用、合成气洗涤塔规格、激冷水系统、激冷室补水线、激冷室至合成气洗涤塔循环线、磨煤系统、锁斗泄压系统、黑水管线材质的选择、烧嘴冷却水罐增加氮封。同时探讨了这些优化对工艺的影响。

Taking a new GE water-coal slurry gasification plant as an example,the process design of GE water-coal slurry gasification is optimized. The process parameters for optimization mainly include the high-pressure nitrogen system,the material and diameter of oxygen manifold pipe,the utility of slurry tank transfer,the specification of syngas scrubber,the quench water system,the adding-water line of quench chamber,the circulating line from quench chamber to syngas scrubber,the coal grinding system,the pressure relief system of lock hopper,the material of black water pipeline and adding nitrogen seal to the injector coolant drum. The effects of these optimizations on the process are also discussed.
