Transformation of automatic preparation of sodium hydroxide solution for vinyl chloride alkaline washing tower
In response to the problems of large fluctuations in alkaline solution concentration and un-stable addition amount in the vinyl chloride alkali washing tower,poor accuracy of manual alkali prepara-tion and high labor intensity,an automatic alkali preparation process transformation was carried out.The transformation plan,the setting of the automatic alkali preparation program,and the transformation effect were introduced.After the transformation,the automation level and operation stability of the system were improved,and safety risks was reduced.
