Study On Process Improvement Of Chlor-alkali Production Plant

Based on the present situation of application technology of chlor-alkali production plant in HeBei Chemical Industry Co.,Ltd.,this paper analyzes and analyzes the existing technical problems and energy saving measures.By exploring the optimum blending ratio of sea salt and well salt,the method of delaying the wear rate of ceramic film and improving the capacity of denitrator,prolonging the service life of nanofiltration membrane and other methods to solve a series of technical problems,through the theoretical calculation to extend the resin tower regeneration And the feasibility of running different load in different time periods under non-full load,and realize the purpose of reducing costs.The results show that the addition of the diversion frame in the salt pond can prolong the contact time between the salt and the brine,reduce the "drift" of the salt and salt with the salt water,and save the concentrate and achieve at the ratio of 4:1 to the salt Safe and stable operation of the best combination of points;through the application of double salt pool,fold tank to increase the filter,ceramic membrane inlet to increase wear-resistant end of the way to effectively delay the ceramic film end wear rate;by increasing the number of nanofiltration,7-4 secondary filter for the 8-4-2 three filter can extend the average life of nanofiltration membrane.It is possible to reduce the regeneration cost by ensuring the regeneration time of the resin tower under the condition of ensuring the quality of the brine at one time.The operation load of the different time periods under different load operation can save the electricity price according to the peak and valley price.
