氨制冷系统中液氨储罐工艺流程优化设计

Optimization Design of Liquid Ammonia Storage Tank in Ammonia Refrigeration System

氨制冷系统目前广泛应用于石油化工领域,但是由于氨有毒可燃的理化特性,在存储中须要引起高度重视。首先介绍了氨制冷系统的组成,然后通过对原有项目中液氨储罐流程进行分析,从安全方面考虑液氨储罐的主要管道包括液氨入口管道、出口管道、气氨管道及事故态泄放管道,提出存在的问题,针对存在的问题有针对性的进行优化设计,最终主要从自动化仪表、阀门的设置、报警系统设置及消防喷淋系统设置等方面提出意见和建议。

Ammonia refrigeration system has been widely applied in petrochemical industry,however great attention should also be paid to its storage due to the toxic and combustible characteristics of ammonia.Firstly,the composition of the liquid ammonia storage tank was introduced.Then the existing problems were put forward through the analysis of the liquid ammonia storage tank process in the original project and considering the main pipelines of the liquid apimpemlionnei aa nstdo raacgcie d teannt kd ifsrcohma r tghee p siapfeeltiyn e.a s pAeccct,o ridnicnlgu dtion tg h lei qeuxiids t ianmg mproonbila e imnls,e tt hpei poeplitinme,i zoautitloent dpeipsieglinn ew,a gs acs a rarimemd oonuita.Finally,some suggestions were put forward on the setting of automatic instruments,valves,alarm system and fire sprinkler system.
