Abstract

Apparatus for separating solvent in a feed of solvent and deasphalted oil produced in a deasphalting process includes a feed line (1) for receiving the feed and constructed and arranged to produce a stream (10) of fluid containing supercritical solvent and deasphalted oil. A
substantially horizontally disposed inlet line (10A) receives the stream of fluid and is designed to effect two phase laminar flow at the outlet (51) of the inlet line (10A). The two phase laminar flow has a substantially horizontally disposed interface (51A) that divides the stream into an upper part (55) containing the lighter supercritical solvent which floats on a lower part (56) containing the heavier deasphalted oil.
