“窜压”的表述？ 表示高压气窜入低压容器，一般用breakthrough这个词，但很多人都把它翻译为“突破”，这是不准确的。在我发的“翻译活动讨论（1）”帖子中也出现过这个词，但没有引起大家的注意。 先回复深海的那句翻译： 高压容器里的物料将沿管路窜入低压容器。 the hp vessel contents will breakthrough into lp vessel along xxx pipe. 再贴点资料给大家学习。 the hydrocracker explosion and fire at bp oil, grangemouth refinery. accident summary on saturday 21 march 1987 the hydrocracker unit was being recommissioned following a routine shut down. during the recommissioning a plant trip occurred. this was thought to be a spurious trip and the plant operators started to bring up the unit to normal operating conditions. from then on until the time of the incident the plant was held in stand by condition with no fresh feed. at 07:00 hours the following morning there was a violent explosion and subsequent fire. the explosion could be heard and felt up to 30km away. the explosion centred on a low pressure (lp) separator vessel, v306, which was fabricated from 18mm steel plate and weighed 20 tonnes. the investigation of the accident suggested that an air operated control valve on the high pressure (hp) separator had been opened and closed on manual control at least three times. liquid level in the lp separator fell and the valve was opened. this action allowed the remaining liquid in the hp separator to drain away and for high pressure gas to break through into the lp separator . as the pressure relief on the lp separator had been designed for a fire relief case, not gas breakthrough the vessel subsequently exploded. the control valve did not close automatically because the low low level trip on the hp separator had been disconnected several years earlier. the operators did not trust the main level control reading and referred to a chart recorder for a back up level reading. there was an offset on this chart recorder which led them to assume that the level in the hp separator was normal. 这段话讲的事故大概原因是： 当低分液位下降时，高分上的气动控制阀打开（向低分排液补充液位），由于高分上的低-低液位联锁几年前就已断掉，结果高分中的液体排空，导致高压气窜入低分，但低分上的泄压阀是设计用于火灾泄放工况，不是用于高压气窜入工况，结果低分发生爆炸。 the above info. is excerpted from http://.uk/comah/sragtech/casebpgrang87b.htm [ 本帖最后由 echommm 于 2008-11-22 16:22 编辑 ]查看更多
