The invention relates to a debottleneck solution for a delayed coking unit. More specifically, the present invention relates to the bottoms of vacuum resid delivered through a deasphalting unit to a coker to avoid retrofitting existing cokers for processing heavier feedstocks when there is a change in crude oil slate. Another object of the invention specifically relates to an improved delayed coking product, a process for cracking petroleum residue in a petroleum refinery to convert it into gaseous and liquid product streams and leave solid carbonaceous petroleum coke. 本发明涉及用于延迟焦化装置的去瓶颈解决方案。更具体地，本发明涉及通过脱沥青装置输送到焦化装置的减压渣油的塔底产物，以避免当原油板岩存在变化时，为了加工较重的原料而改造现有的焦化装置。本发明的另一目的具体地涉及改善的延迟焦化产品，在石油炼油厂中用于裂解石油残渣的方法，从而将其转化为气态和液态产品物流并留下固态碳质石油焦炭。
