壳牌煤气化装置氧气管道和渣水管道布置设计的优化

Optimizing for Arrangement Design of Shell Coal Gasification Plant Oxygen Gas Pipeline and Slag Water Pipeline

介绍了壳牌煤气化装置工艺中氧气系统和渣水系统的工艺流程;简述了其管道布置的优化方案。结果表明:①氧气管线布置方案可降低着火风险,旁路和放空管线的设置可最大限度地减少气流旋涡的产生,保证了氧气系统安全稳定运行;②渣水管线布置方案在满足工艺要求的前提下,最大程度地缩短了管路长度,减少了阀门数量,降低了装置投资成本。

Author has introduced the process flows for oxygen gas system and slag water system in Shell coal gasification plant;has briefly described the optimal scheme of its pipeline arrangement.Result indicates：①Arrangement scheme of oxygen gas pipeline can reduce the firing risk,arrangement of bypass and venting pipeline can furthest reduce formation of gas stream vortex ,and it has guaranteed safe and stable operation of oxygen gas system ;②Arrangement scheme of slag water pipeline can maximally shorten pipeline length ,reduce valve quantity and lower investment cost of plant under precondi-tion of satisfying process requirement.
