1.1.本项目工艺设计是在业主的输入文件及业主相关意见基础上开展的。
The process desig n is based on clie nt's in put docume nt and clie nt's releva nt comme nts.
Pitch Column Heater F84103 and circulate this material from the discharge of the heater back through its sucti on .It is importa nt to note the heater throughput does not cha nge, regardless of the qua ntity of treatme nt process feed.
来自焦油塔底泵的拔顶焦油通过焦油进料泵P84111A/B加压送往进料预热器E84122B和E84122A的
壳程，通过吸收处理的拔顶焦油的热量，然后被送往沥青塔加热炉F84103循环。
新鲜物料通过进入沥青塔加热炉循环泵进口管线与循环物料进行混合，通过沥青塔加热炉加热。
从加热炉循环物料溢流进入沥青处理塔T84105和T84106，沥青处理塔能保证停留时间在10〜162min
年操作时间The annual operating time: 7920 hours

本装置主要由焦油加热炉、沥青预处理塔、沥青处理塔、沥青塔循环泵及塔顶冷凝器组成。
This pla nt is con sist of pitch colu mn heater, pitch primary treatme nt vessel, pitch sec on dary treatme nt vessel, treatme nt vessel circulati ng pump, and overhead conden ser.
The topped tar feed then flows into the Pitch Column Heater F84103 circulating loop.
Pitch Heater Circulating Pumps P84113A/B deliver a very high throughput of topped tar through the
