The main factors affecting quality of modified pitch are determined by analyzing the factors affecting qualification rate of modified pitch. They are low content of toluene insoluble in crude tar, flash oil flows backwards, poor cooling effect of flash oil and low degree of polycondensation of modified pitch in the reactor. The qualification rate of modified pitch is significantly improved by such measures as reducing rotate speed of centrifuges, transforming gas collecting tube of flash oil, absorption tube of flue gas and position of cooler of flash oil, increasing the softening point of mid-temperature pitch and temperature of reactor.

通过对影响改质沥青合格率的因素的分析,确定了影响改质沥青质量的主要因素为原料焦油甲苯不溶物含量低、闪蒸油倒流、闪蒸油冷却效果差、改质沥青在反应釜内缩聚程度低。通过降低离心机转速、对闪蒸油集气管、烟气吸收管道、闪蒸油冷却器位置的改造、提高中温沥青软化点、提高反应釜温度等措施,改质沥青合格率明显提高。

通过对影响改质沥青合格率的因素的分析,确定了影响改质沥青质量的主要因素为原料焦油甲苯不溶物含量低、闪蒸油倒流、闪蒸油冷却效果差、改质沥青在反应釜内缩聚程度低。通过降低离心机转速、对闪蒸油集气管、烟气吸收管道、闪蒸油冷却器位置的改造、提高中温沥青软化点、提高反应釜温度等措施,改质沥青合格率明显提高。

改质沥青  /  甲苯不溶物含量  /  合格率

The main factors affecting quality of modified pitch are determined by analyzing the factors affecting qualification rate of modified pitch. They are low content of toluene insoluble in crude tar, flash oil flows backwards, poor cooling effect of flash oil and low degree of polycondensation of modified pitch in the reactor. The qualification rate of modified pitch is significantly improved by such measures as reducing rotate speed of centrifuges, transforming gas collecting tube of flash oil, absorption tube of flue gas and position of cooler of flash oil, increasing the softening point of mid-temperature pitch and temperature of reactor.
