摘　　要：焦化硫铵系统生产的硫铵颜色异常红色,影响硫铵售价,对系统进行了生产工艺对照、工序影响因素排查和大量的实验研究工作,排除了铁离子是造成硫铵颜色异常的主因,基本确定了煤气在通过脱硫液时带入了部分二苯酚,导致硫铵出现红色现象。The color of ammonium sulfate was abnormal red, the price of the ammonium sulfate was influenced lower. Through the production process comparison,process factors analysis and a large number of experimental investigation and research work, the color of iron as the main cause of abnormal was ruled out. Some two phenol carried into the production process by the gas through desulfurization solution was basically determined that lead to the abnormal red.
