[交流] 【求助】求翻译石化方面的4句话

In addition to the high sweep gas, it was determined that the overall flow from the Crude/SRU/SCOT Tail Gas was 6,200 standard cubic metres per day that was considered to be abnormally high. After reporting the results to the customer and looking at possible causes for this high flow rate operators closed the nitrogen purge to an offline compressor to examine its contribution to the flare. Subsequent flow rate measurement showed a dramatic decrease of 4,600 standard cubic metres per day. It was determined that the process valve for the nitrogen purge was open more than necessary to maintain purging of the compressor.

试译,供参考。

除了吹扫气体流量较高外,发现Crude/SRU/SCOT的尾气总流量也异常高,达到6200标准立方米/天。在告知客户有关结果,并检查了造成如此高流量的可能原因之后,操作人员关闭了通向一个离线压缩机上的氮气吹扫,以检验其对流量暴增的影响。检测发现,气体流速骤降了4600标准立方米/天。原来,控制吹扫压缩机的氮气调节阀一直打开着。

初步检测发现,不仅吹扫气体流量异常高,而且Crude/SRU/SCOT的尾气总流量也异常之高,达6200标准立方米/天。操作人在告知用户相关结果并查询流量激增的可能原因后,关闭了通向一台离线压缩机的吹扫氮气,以检验吹扫氮气对火炬流量激增
的贡献。后续检测发现,气体流速骤降了4600标准立方米/天。最终检测结果证实,尾气总流量异常原因在于压缩机的吹扫氮气控制阀开度超过设定值。
