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 the maleic anhydride production unit, the water used in the process must be demineralized water with potassium and sodium ion content less than 3ppm. The contents of crude maleic anhydride in crude maleic anhydride storage tank and process water storage tank and potassium and sodium ions in process water shall be regularly detected 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,然后立即對脫水精制系統(tǒng)進(jìn)行清洗操作。
If the content of potassium and sodium ions in crude maleic anhydride exceeds 5ppm or the content of potassium and sodium ions in process water exceeds 3ppm during dehydration and refining, the operation of this batch of refining system shall be temporarily stopped and reported to the management department immediately. After obtaining the consent of the management department and under the supervision of the competent technical and management personnel, this batch of refining operation shall be completed, Then immediately clean the dehydration and refining system.
如果工藝水儲罐的工藝水中鉀、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,使工藝水儲罐中的鉀、鈉離子含量合格。
If the potassium and sodium ions in the process water in the process water storage tank exceed 3ppm, the method of replacing with qualified process water shall be adopted 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(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 crude maleic anhydride in crude maleic anhydride storage tank exceed 3ppm, the temperature in the distillation kettle shall be strictly monitored for distillation operation, and the system shall be cleaned immediately after completing this batch of refining operation.
