3×10^(4)Nm^(3)/h制氢装置PSA产能不足情况分析及措施

Analysis and Measures of Insufficient PSA Production Capacity of 3×10^(4)Nm^(3)/h Hydrogen Production Unit

针对某炼化公司3×10^(4)Nm^(3)/h制氢装置在2015年检修后出现的PSA产能不足问题进行了说明和原因分析,分别采用了更换内漏程控阀、单塔切除试验吸附剂是否失效、增加限流孔板减少气体对吸附剂磨损、以及内部程序检查修改等方法来处理,最终解决了产能问题,满足生产的需要。

The problem of insufficient PSA production capacity after overhaul of 3×10^(4)Nm^(3)/h hydrogen production unit in 2015 was explained and the reasons were analyzed,to solve the problem of production capacity,the methods such as replacing the internal leakage program control valve,whether the single tower cut off test adsorbent is invalid,increasing the orifice plate to reduce the gas abrasion to the adsorbent,and checking and modifying the internal program were adopted respectively,to meet the demands of production.
