摘要: A process is disclosed of separating fine solids from oil in which the solids are dispersed which comprising contacting said oil with a combination of a compressed above-critical gas and an entraining agent at such temperature and such pressure that the system consisting of the oil, entraining agent and above-critical gas constitutes a single phase, withdrawing and separating the so-withdrawn phase into a liquid phase rich in oil and a gas phase lean in oil, the single-phase mixture of oil, entraining agent and above-critical gas from the solids.
