A gas stream containing CO. sub. 2 and H. sub. 2 S is contacted with an alkanolamine in a contacting zone. The rich solution is then selectively stripped in a stripping zone to produce a gas stream containing a higher CO. sub. 2 :H. sub. 2 S mole ratio than the initial stream. This stream can be recycled to the alkanolamine contacting zone. The partially stripped solution can be introduced into another stripping zone to provide a third gas stream which is rich in H. sub. 2 S and lean in CO. sub. 2 suitable as feed for a Claus Unit and a lean alkanolamine solution which can be recycled to the contacting zone.

A process for recovering oil from oil wet and particularly from oil-wet, acidic tar sands is described in which these sands are subjected to vigorous fluidization in the presence of water, air and a surfactant but in the absence of an extraneous hydrocarbon solvent. This step produces a multiphase mixture including an oil containing froth enabling gravity separation, e. g. in hydrocyclone.

Demetallized hydrocarbon feedstock is obtained from heavy oils by first solvent extracting the heavy oils and then demetallizing the extract in a magneto-filtration step. In another embodiment, diamagnetic nickel complexes in hydrocarbon oils are first converted to a paramagnetic product and the oil stream thereafter is passed through a magneto-filtration operation.
