The present invention is an in-situ apparatus for generating carbon dioxide gas at an oil site for use in enhanced oil recovery (EOR). The apparatus includes a steam generator adapted to boil and superheat water to generate a source of superheated steam, as well as a source of essentially pure oxygen. The apparatus also includes a steam reformer adapted to react a carbonaceous material with the superheated steam and the pure oxygen, in an absence of air, to generate a driver gas comprising primarily carbon dioxide gas and hydrogen gas. A separator is adapted to separate at least a portion of the carbon dioxide gas from the rest of the driver gas to generate a carbon dioxide-rich driver gas and a hydrogen-rich fuel gas. A compressor is used for compressing the carbon dioxide-rich driver gas for use in enhanced oil recovery, and the compressed carbon dioxide-rich driver gas, with substantially no oxygen, is injected to a predetermined depth in order to enhance oil recovery at the oil site. Unlike traditional CO 2 -EOR, which requires large power plants stationed near metropolitan areas and expensive pipeline networks, the in-situ apparatus can be placed or constructed at the site of the oil field, while a portion of the carbonaceous material may be obtained from a site outside the oil field.

A process is described for separating a gas stream containing hydrogen sulfide (H 2 S) impurities into a hydrogen (H 2 ) rich vapor stream, a carbon dioxide (CO 2 ) stream and an H 2 S rich vapor stream in an apparatus that comprises a compression and/or cooling system comprising at least one compressor and/or heat exchanger and a gas-liquid separator vessel, and an H 2 S recovery unit. In examples, the process comprises the steps of: (a) feeding the gas stream to the compression and/or cooling system such that carbon dioxide in the gas stream condenses to form a two-phase stream; (b) passing the two-phase stream either directly or indirectly to a gas-liquid separator vessel and withdrawing a hydrogen rich vapor stream and a liquid CO 2 stream containing dissolved H 2 S impurities from the separator vessel; (c) passing the liquid CO 2 stream containing dissolved H 2 S impurities to an H 2 S recovery unit comprising an evaporator/condenser in which the CO 2 and H 2 S are vaporized and an H 2 S absorber in which the gaseous H 2 S and CO 2 are separated, wherein the two phase stream passed to the separator is at a pressure of from 80 bar to 400 bar. In some applications, the pressure of the H 2 S recovery unit is at least 30 bar. In a preferred example, residual CO 2 in the hydrogen rich vapor stream is removed in an optional step by solvent extraction in a CO 2 absorber most preferably in a configuration where the H 2 S and CO 2 absorbers share the same (preferably methanol) solvent.
