补充资料:延迟焦化
分子式:
CAS号:

性质:渣油先经加热进入焦炭塔后再进行焦化反应的过程。是一种半连续工艺过程。一般都是一炉(加热炉)二塔(焦化塔)或二炉四塔,加热炉连续进料,焦化塔轮换操作。它是目前世界渣油深度加工的主要方法之一。原料油(减压渣油或其他重质油如脱油沥青、澄清油甚至污油)经加热到495~505℃进入焦炭塔,待陆续装满(留一定的空间)后,改进入另一焦炭塔。热原料油在焦炭塔内进行焦化反应,生成的轻质产物从顶部出来进入分馏塔,分馏出石油气、汽油、柴油和重馏分油。重馏分油可以送去进一步加工(如作裂化原料)也可以全部或部分循环回原料油系统。残留在焦炭塔中的焦炭以钻头或水力除焦卸出。焦炭塔恢复空塔后再进热原料。该过程焦炭的收率随原料油残炭而变,石油气产量一般10%(质量)左右,其余因循环比不同而异,但柴/汽比大于1。
