Abstract
Disclosed are process and system for making an asphalt product and an olefin product from an asphaltenes-rich feed without using a vacuum distillation column. The feed is first deep stripped in a first stripping column using a stripping vapor such as steam and/or a C2-C3 paraffins-rich stream to obtain a bottoms liquid effluent having a high cutpoint and an overheads effluent comprising gas oil, lighter hydrocarbons, and the stripping vapor. The high-boiling point bottoms liquids effluent, with optional additional separation and/or treatment, can be used as asphalt products. The overheads effluent, with optional additional separation, can be fed into a pyrolysis furnace cracker, where it is converted into a cracker product mixture comprising olefins, lighter hydrocarbons, hydrogen, and the like, which can be recovered in a products recovery subsystem.
