我公司加氢反应器原料固含量的粒径小(基本在20ppm以内),原有滤芯采用不锈钢楔形丝网,过滤效果不理想,不知道大家都采用什么型式的滤网

其实加氢原料里固体颗粒含量很少很少,比较麻烦的胶质类物质。这种物质粒径小,常规的丝网一类的过滤元件很难去除。得用专用脱胶质的滤芯式

加氢的过滤器滤芯一般在25微米,哪一种加氢的原料要求都是不含固含的,过滤器精度一般都能符合要求。除非是过滤器滤芯漏了或开副线了。但是无论哪一种滤芯,反冲的时候,都会有一定量油不过滤芯,被直接带走,这是设计问题,不是过滤器的问题。

很多反冲洗说,我的过滤精度是25微米的 。可是在实际运行的时候,看看反冲洗频繁不频繁,看看反应器的压降上升快不快吧。我见过几分钟就反冲洗的,也见过反应器压降1个月就起来的

基本上都用楔形丝滤管,大部分都在煎熬中,到目前没有革命性的滤元出现

就是。但是无论如何要保护好反应器中催化剂。不能反应器压降很快就上升
