正确答案
由界区外来的低压重烃火炬气(440LFV106-52”-C2C-GC2)、经低压重烃分液罐(440V104)分液后通过低压重烃水封罐(440V105)、由界区外来的超低压重烃火炬气(440LFV102-48”-C2C.、经超低压重烃分液罐(440V102)分液后通过超低压重烃水封阀(440V103),二股气体合并成一根总管(440LFV109-64”-C2C-GC2)送低压重烃火炬筒体(440FL102C.经流体密封器进入低压重烃火炬头(440FL102A.燃烧排放。正常生产时低压重烃、超低压重烃小流量火炬气分别从各自的总管上引出一根支管(440LFV110-8”-C2C-GC2)、(440LFV105-8”-C2C.经安全水封罐(440V108)后送酸性火炬筒体辅管(440LFV111-16”-C2C-GC2)经流体密封器送酸性火炬头(440FL103A.燃烧排放。
