- manufacturer of potash to remove ammonia process research Appropriate chemical industry
potash has a widespread application in the industry, China's potash manufacturer mainly by ion exchange method to proceed with production, ion exchange method in our country already has a history of three hundred and forty years.
potash manufacturer has been in the study of ion exchange, carbide and waste water treatment, but there's a small amount of ammonium bicarbonate in ion exchange completion fluid processing is still in a low stage, further studies are needed in addition to ammonia process.
potash factory processing phase before evaporation to remove ammonia method for heating evaporation, is before entering the evaporation stage, using indirect heating steam heating, ammonium bicarbonate of decomposition, the majority of ammonium hydrogen carbonate into the evaporation stage.
enter after the evaporation stage, to complete the liquid potash producer adopts steam formulation, in addition to ammonia, packing the top add heat to a certain temperature of ion exchange liquid, bottom heating air is piped in, bottom effluent continue to enter the preheater and mixed, and raw material liquid circulation desorption material liquid. Rise of heated air and ion exchange liquid inside the packed tower fully contact and exchange of quality and energy exchange, so that the material liquid rapid decomposition, more fully improve carbon dioxide and ammonia content in the gas, is conducive to the concentration of the gas collection and use again.
potash manufacturers to study the temperature and the ratio of gas and liquid, stripping time and initial concentration of ammonium hydrogen carbonate decomposition rate, the influence of the ammonium bicarbonate to choose the best except ammonia conditions, practice shows that this method has a good effect of ammonia, save the steam consumption at the same time has achieved good economic benefits.
