Process And Apparatus for Cracking High Boiling Point Hydrocarbon Feedstock |
摘要 |
In one aspect, the invention includes in a process for cracking a hydrocarbon feedstock comprising: a) feeding a hydrocarbon feedstock containing at least 1 wt % of resid components having boiling points of at least 500° C. to a furnace convection section to heat the feedstock; b) flashing the heated feedstock in a first flash separation vessel to create a first overhead stream and a first bottoms liquid stream; c) hydrogenating at least a portion of the first bottoms liquid stream to create a hydrogenated bottoms stream; d) flashing the hydrogenated bottoms stream in a second flash separation vessel to create a second overhead stream and a second bottoms liquid stream; e) cracking the first overhead stream and the second overhead stream in a cracking furnace to produce a pyrolysis effluent stream. In other embodiments, the process further comprises heating the hydrocarbon feedstock in step a) to a temperature within a range of from 315° C. to 705° C.
