Improvement and optimization of VOCs treatment process in desulfurization and ammonium sulfate process
The VOCs treatment process of desulfurization ammonium sulfate process in Qian'an Zhonghua Coal Chemical Co.,Ltd.was introduced.In response to the problems of high operating resistance of the water scrubber,corrosion of the pickling tower,and discharge of washing tower waste liquid during the operation,measures had been taken to change the makeup water of the water scrubber into industrial water,optimize the replacement liquid volume and pH control of the pickling tower,modify the acid adding pipeline of the pickling tower,and change the discharge location of the washing tower waste liquid.The optimization and transformation had achieved protection of the coke oven heating system.
