摘　　要：研究了中和塔法粗轻吡啶装置堵塞物的性状,结果表明,堵塞物由硫酸铵结晶和焦油次生QI组成,并带有少量煤和焦的粉尘.在探明成因的基础上,提出了减轻设备堵塞的相应的措施。The beahavior of the plugging substance in the equipment producing light crude pyridine is studied.The result shows that the plugging substance consist of crystallyzed sulphur ammonium and the secondary QI thermal polymer,and contains coal and coke powders in small amount.The appropriate measures taken to lighten the plugging of the equipment are put forward based on the generation of plugging substance mantioned.
