Methanol synthesis using captured CO2 as raw material

The purpose of this paper is to assess via techno-economic and environmental metrics the production of methanol (MeOH) using H 2 and captured CO 2 as raw materials. It evaluates the potential of this type of carbon capture and utilisation (CCU) plant on (i) the net reduction of CO 2 emissions and (ii) the cost of production, in comparison with the conventional synthesis process of MeOH Europe.

Taking the heat

“Twin string” means that there are two parallel feeding lines inside, which makes production more flexible. The raw meal then flows down to cyclones and is progressively heated by rising hot gas. Normally the raw material is 90 percent decarbonated and at 1,450 degrees Celsius when it is fed into the rotary kiln and converted to clinker.
