<p>A method of hydrocarbon recovery, utilising captured acidic gas comprises contacting a gas comprising an acidic gas such as carbon dioxide (CO2) with brine to produce acidic gas-rich brine and acidic gas-depleted gas. The acidic gas-rich brine is de-pressurised preferably in a flash unit 114, to obtain pure acidic gas and brine and a hydrocarbon recovery is conducted using the pure acidic gas. The contacting may take place in an absorption column 101 or a horizontal tunnel comprising treatment sections. The hydrocarbon recovery is preferably an oil recovery technique such as carbon dioxide flooding where CO2, is injected into a hydrocarbon reservoir to increase reservoir pressure thereby increasing the drive of hydrocarbons out of the reservoir.</p> |
