The project is located tar distillation site.年操
7、作时间The annual operating time: 7920 hours2. 流程说明PROCESS DESCRIPTION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 plant is consist of pitch column heater, pitch primary treatment vessel, pitch secondary treatment vessel, treatment vessel circulating pump, and overhead condenser.来自焦油塔底泵的拔顶焦油通过焦油进料泵P8411
8、1A/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10162min内。每个塔在正常流量(29,813kg/h)时，停留时间保持在81min。T84106塔底物料处理后的拔顶焦油经沥青塔循环泵P84115A/B，由T84106液位变送器控制进入杂酚油塔。沥青处理塔塔顶产生的含有轻油的气体和不凝气进入塔顶冷凝器E84123冷却，液相进入凝液回收罐
9、V84111，通过LT84133控制进入原中间罐组。气体进入气液分离器V84112和V84114进行分离后作为沥青塔加热炉及原有加热炉的燃料，重新回收利用。事故气体及安全阀泄放气体拟进入待建火炬系统。Feed for the treatment process is topped tar drawn from the discharge of the Tar Column Reboiler Pumps. This material is delivered to Treatment Feed Pumps P84111A/B, which boost the pressure to that r
10、equired for pitch yield improvement.The topped tar from bottom of tar column flows the shell sides of Treatment Feed Preheaters E84122B then E84122A, recovering heat from the treated topped tar leaving the treatment process. The topped tar feed then flows into the Pitch Column Heater F84103 circulat
11、ing loop.Pitch Heater Circulating Pumps P84113A/B deliver a very high throughput of topped tar through the Pitch Column Heater F84103 and circulate this material from the discharge of the heater back through its suction. It is important to note the heater throughput does not change, regardless of th
12、e quantity of treatment process feed.Fresh feed mixed into the circulating flow at the circulating pump suction. This incoming feed tends to cool the circulating fluid, forcing additional heater firing.The treatment process feed overflows the Pitch Column Heater F84103 circulating loop and flows to
13、the treatment vessel that can be adjusted for a variety of residence times from about 10 minutes through to 162 minutes. Each vessel provides sufficient capacity for 81 minutes residence time at the normal process feed rate (29,813kg/h).The treatment process product is treated topped tar which is fr
14、om the Treatment Vessel Circulating Pumps P84115A/B discharge. It flows to the Creosote Column as feed under control of the level controller at Pitch Secondary Treatment Vessel T84106.The treatment vessels T84105 and T84106 produce an overhead stream consisting of light oil vapor and non-condensable
15、 gases. This stream flows to condenser E84123 where the gases are cooled and the vapors are cooled and condensed.The condensate flows to Condensate Receiver V84111 where the condensate is collected before being blown to storage under level control LT84133.The gases separate from the liquid in E84123 and are vented through separator V84112 to flowing to the F84103 and existing heater as fuel.Relief valve discharge and incident gas during production flow to flare system that will be built.3. 设
