順酐裝置中,工藝過程使用的水都必須是鉀、鈉離子含量小于3ppm的脫鹽水。每天都應(yīng)定時(shí)檢測(cè)粗順酐儲(chǔ)罐和工藝水儲(chǔ)罐中的粗馬來酐和工藝水中的鉀、鈉離子含量。
In maleic anhydride production plant, the water used in the process must be desalted water with potassium and sodium ion content less than 3ppm. The contents of crude maleic anhydride and potassium and sodium ions in process water and crude maleic anhydride storage tank should be detected regularly every day.
如果在脫水精制過程中發(fā)現(xiàn)粗順酐中的鉀、鈉離子含量超過5ppm或工藝水中鉀、鈉離子含量超過3ppm時(shí),都應(yīng)暫時(shí)停止該批精制系統(tǒng)操作,并立即向管理部門報(bào)告,在得到管理部門同意后并在主管技術(shù)和管理人員的監(jiān)督下完成該批精制操作,然后立即對(duì)脫水精制系統(tǒng)進(jìn)行清洗操作。
If the content of potassium and sodium ions in the crude maleic anhydride exceeds 5ppm or the content of potassium and sodium ions in the process water exceeds 3ppm, the operation of this batch of refining system should be temporarily stopped and reported to the management department immediately. After obtaining the approval of the management department and under the supervision of the competent technical and management personnel, the batch of refining operation should be completed, and then the dehydration refining system should be started immediately Carry out cleaning operation.
如果工藝水儲(chǔ)罐的工藝水中鉀、鈉離子超過3ppm,則應(yīng)立即采取用合格的工藝水置換的方法,使工藝水儲(chǔ)罐中的鉀、鈉離子含量合格。
If the potassium and sodium ions in the process water of the process water storage tank exceed 3ppm, the qualified process water shall be replaced immediately to make the potassium and sodium ions in the process water storage tank qualified.
如果粗順酐儲(chǔ)罐的粗順酐中鉀、鈉離子超3ppm,則應(yīng)嚴(yán)格監(jiān)視蒸餾釜內(nèi)的溫度進(jìn)行蒸餾操作,完成本批精制作業(yè)后立即清洗系統(tǒng)。
If the potassium and sodium ions in the crude maleic anhydride storage tank exceed 3ppm, the temperature in the still should be strictly monitored for distillation operation, and the system should be cleaned immediately after finishing this batch of refining operation.
