Oil sand production without co2 emission

Abstract

A plant for generation of steam for oil sand recovery from carbonaceous fuel with capture of COfrom the exhaust gas, comprising heat coils (″) arranged in a combustion chamber () to cool the combustion gases in the combustion chamber to produce steam and superheated steam in the heat coils, steam withdrawal lines () for withdrawing steam from the heat coils, an exhaust gas line () for withdrawal of exhaust gas from the combustion chamber (), where the combustion chamber operates at a pressure of 5 to 15 bara, and one or more heat exchanger(s) () are provided for cooling of the combustion gas in line (), a contact device () where the cooled combustion gas is brought in countercurrent flow with a lean COabsorbent to give a rich absorbent and a COdepleted flue gas, withdrawal lines () for withdrawal of rich absorbent and COdepleted flue gas, respectively, from the contact device, the line () for withdrawal of COdepleted flue gas being connected to the heat exchangers () for heating of the COdepleted flue gas, and where the rich absorbent is regenerated an absorbent regenerator (), the regenerated lean absorbent is recycled to the absorber (), and a gas withdrawal line () connected to the absorber for withdrawal of COand steam from the regenerator (), is described.
