摘要
A process and system for producing deasphalting and demetallized oil from an initial feed such as a heavy feed is provided. The feed is contacted with an effective quantity of solvent to promote phase separation, to produce an asphalt phase and a reduced asphalt content phase. The reduced asphalt content phase is contacted with an effective amount of solid adsorbent to remove undesirable metal compounds to produce an oil phase substantially-free of asphalt and substantially-free of metal. The oil phase that is substantially-free of asphalt and substantially-free of metal is subjected to flash separation to produce a solvent fraction for recycle and an oil phase effluent substantially-free of asphalt and substantially-free of metal for recovery as the desired product.
