["常减压装置循环水量超标如何解决?"
Reply #32011-07-03
"我装置循环水自开工以来用量一直都超标不知道哪位有好的办法解决 我装置循环水走向是 进装置去减顶水冷初常顶水冷各侧初水冷机泵用冷却水"

"有一些办法的:一是联系循环水开始阶段开启风机尽量把进装置的水温降下来。二是提高各油品到达冷切器前所经换热器的换热效率有必要抽芯清洗也是可以的。三是用冷切器的出口阀门进行控制有必要冷切器也要进行清洗!"

"我的装置基本不用水冷常一常二线用的是空冷常顶减顶是湿式空冷无后冷消耗少量除氧水。最关键的蜡油侧线水冷基本不开这就要全厂协调罐区采用热罐储存并监控好这几个罐的加热盘管不要有泄漏情况并且不接卸外采可能含水较大的的蜡油避免冒罐。毕竟蜡油都是给催化吃的热点也有好处。所以到头来开着开着水冷只有减一回流水冷控制减顶温度)减一外送在水冷前。"

"控制各侧线出装置的温度偏上限控制关闭各备泵的循环水量"

"可以考虑下装置的热进料省去冷却后再提温过程"

"各侧线冷后温度尽量上限指标控制控制好每台水冷器的循环水温差"
