順酐生產裝置中,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。每天都應定時檢測粗順酐儲罐和工藝水儲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現粗順酐中的鉀、鈉離子含量超過5ppm或工藝水中鉀、鈉離子含量超過3ppm時,都應暫時停止該批精制系統操作,并立即向管理部門報告,在得到管理部門同意后并在主管技術和管理人員的監督下完成該批精制操作,然后立即對脫水精制系統進行清洗操作。
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.
如果工藝水儲罐的工藝水中鉀、鈉離子超過3ppm,則應立即采取用合格的工藝水置換的方法,使工藝水儲罐中的鉀、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.
如果粗順酐儲罐的粗順酐中鉀、鈉離子超3ppm,則應嚴格監視蒸餾釜內的溫度進行蒸餾操作,完成本批精制作業后立即清洗系統。
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.
