The project is located

5、 tar distillation site.年操作時(shí)間The annual operating time: 7920 hours2. 流程說明PROCESS DESCRIPTION本裝置主要由焦油加熱爐、瀝青預(yù)處理塔、瀝青處理塔、瀝青塔循環(huán)泵及塔頂冷凝器組成。This plant is consist of pitch column heater, pitch primary treatment vessel, pitch secondary treatment vessel, treatment vessel circulating pump, and overhead condenser

6、.來自焦油塔底泵的拔頂焦油通過焦油進(jìn)料泵P84111A/B加壓送往進(jìn)料預(yù)熱器E84122B和E84122A的殼程，通過吸收處理的拔頂焦油的熱量，然后被送往瀝青塔加熱爐F84103循環(huán)。新鮮物料通過進(jìn)入瀝青塔加熱爐循環(huán)泵進(jìn)口管線與循環(huán)物料進(jìn)行混合，通過瀝青塔加熱爐加熱。從加熱爐循環(huán)物料溢流進(jìn)入瀝青處理塔T84105和T84106，瀝青處理塔能保證停留時(shí)間在10162min內(nèi)。每個(gè)塔在正常流量(29,813kg/h)時(shí)，停留時(shí)間保持在81min。T84106塔底物料處理后的拔頂焦油經(jīng)瀝青塔循環(huán)泵P84115A/B，由T84106液位變送器控制進(jìn)入雜酚油塔。瀝青處理塔塔頂產(chǎn)生的含有輕油的氣體和不凝氣

7、進(jìn)入塔頂冷凝器E84123冷卻，液相進(jìn)入凝液回收罐V84111，通過LT84133控制進(jìn)入原中間罐組。氣體進(jìn)入氣液分離器V84112和V84114進(jìn)行分離后作為瀝青塔加熱爐及原有加熱爐的燃料，重新回收利用。事故氣體及安全閥泄放氣體擬進(jìn)入待建火炬系統(tǒng)。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 boo

8、st the pressure to that required 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 Colu

9、mn Heater F84103 circulating 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

10、 change, regardless of the 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 circu

11、lating loop and flows to 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 treat

12、ed topped tar which is from 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

13、vapor and non-condensable 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

14、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. 設(shè)計(jì)規(guī)范 Code and Specification for DesignØ 石油化工企業(yè)設(shè)計(jì)防火規(guī)范GB50160-2008Fire preven
