Improvement And Application Of Ammonium Sulfate Recovery Process From Coke Oven Gas

Focus on the Problems in Practical Production of the Recovery Process of Ammonium Sulphurium by Saturator,the process optimization scheme was proposed.The rationality of the study is the selection of process design,the controlling of operating conditions in production process and comprehensive treatment of tail waste.By retype the gas preheater,the fog trap,material of main process pipeline and so on in the existing ammonium sulfate recovery process,optimization of production process is realized,the operational stability of the system is improved.Through the modification of the dry bed and the improvement of environment.Through the improvement of ammonium sulphur packaging process,increased automation level of ammonium sulfate production process,manpower costs has been saved.By collecting the exhaust gas from the tank,the smell has been controlled.The external corrosion of the equipment is controlled too.At the same time,ammonia gas from other processes was collectted,the yield of products is increased.By received the waste liquid from flue gas desulfurization process,indirect reduction of acid consumption index.By treating dry tail gas,reduced particulate matter emissions.ultra low emission standards were metThrough the optimization of the recovery process of ammonium sulphurium by existing saturator,stabilized the operations of ammonium sulfate,increased levels of automation.and gradually adapt to the development requirements of environmental protection work Figure14;Table29;Reference51...
