Analysis and Optimization of Gas System Operation Control for 600000 t/year Ammonium Phosphate Plant
An analysis was conducted on the environmental pollution caused by the direct discharge of dusty gas from fluidized cooling during the production process of Yunnan Tian'an Chemical Co.,Ltd.'s Phase Ⅱ 600000 t/year diammonium phosphate plant,the failure to meet control in-dicators for product temperature,high particulate matter emissions from chimneys,and high neutralization degree of washing solution in the washing system.Improvement measures for operational control were proposed,and significant optimization effects were achieved.
