Abstract: An apparatus for producing methanol from carbon dioxide. The apparatus includes a first circulation process for a circulating water and methanol which includes an absorption stage for carbon dioxide, a desorption stage with a hydrogen feed, a first heat exchanger, an outlet, a circulation pump, and an expansion throttle. The second circulation process for methanol, water, carbon dioxide and hydrogen includes the desorption stage, a first liquid-gas phase separation stage with a return conduit for liquid phases to the desorption stage, and a gas outlet from and an inlet into the desorption stage. The third circulation process for carbon dioxide and hydrogen includes a methanol synthesis reactor, a gas outlet of the first liquid-gas phase separation stage which opens out into the third circular conduit and an inlet into which the third circular conduit opens, a second heat exchanger, a gas outlet in the third circular conduit, and a fan.

Abstract: A method and apparatus for producing carbon monoxide, wherein the carbon monoxide is formed from a gaseous feed which includes at least carbon dioxide. The method includes supplying oxygen to a carbon dioxide stream for forming a carbon dioxide based mixture, supplying the carbon dioxide based mixture to a hydrogen based stream to form the gaseous feed, supplying a hydrocarbon containing stream to the hydrogen based stream before the supply of the carbon dioxide based mixture, feeding the gaseous feed into a reactor which includes at least one catalyst, treating the gaseous feed by partial oxidation in the reactor so that carbon dioxide reacts with hydrogen in the reactor in presence of oxygen and heat is formed during the reaction, and recovering a product composition including at least carbon monoxide and hydrogen from the reactor.
