On May 09, 2019, at 08:55 a.m., Pan Bo, a person in the F13 position of Meropinan Rough, conducted meropinan rough (F13) on the first floor south of Y77 (batch: 2087-- 190503-4C) when prepared, after the hydrogenation reaction is completed, the hydrogenation reaction fluid is filtered from the hydrogenation reactor tank H1001-1 to the crystalline tank H1003 for crystallization, during the filtration process, It found that the temporary Meropinan special line connected to the filter had liquid seeping out, which did not meet the production requirements. <br><br>The reason for this deviation is that the post operator Ye Xiaobing and Pan Bo in the temporary pipe cleaning after and before the use of the gasket is not intact inspection, and H3-SOP-65161-11 Y77 Merropnan crude post operating procedures do not clearly provide for the use of temporary lines must be checked gasket shims intact, resulting in the use of damaged gaskets in production, so that the filter and temporary line interface liquid seeping out. <br><br>The deviation occurs because the post operator after the temporary line cleaning and before the use of the gasket is not intact inspection, resulting in the filter and temporary line interface material seepage, but the material fluid seepage at the beginning of the filtration is found, and the post personnel immediately stop filtration until the replacement of the new gasket after the restart of filtration, in the process the liquid has gas nitrogen protection and replace the new gasket for a short time, so it will not affect the quality of the Merofinan crude (F13). Follow-up follow-up yield, at 2019.05.09 11:38 after the end of the discharge, obtained the Merofinan crude (F13) 20.3Kg, the yield of 60.90%, in the normal range.<br><br>1. Take this deviation as an example, train the staff, emphasizing that after cleaning and before use, check whether the gaskets of temporary lines are in tact, if there is damage, replace the new gaskets in a timely manner.<br>2. Revise H3-SOP-65161-11 Y77 Merropinan rough post operating procedures, clearly stipulates that before the use of temporary lines must check the gasket is intact, otherwise, replace the new gasket in a timely manner.
