Abstract
A process for producing methanol, where a hydrocarbon feedstock () is reformed and a make-up syngas is reacted in a synthesis loop, obtaining crude methanol which is further treated to obtain high-grade methanol, and where the carbon dioxide dissolved in the crude methanol is recycled to the reforming section in order to adjust the stoichiometric number of the make-up syngas. In a preferred embodiment, a flash gas () separated from the crude methanol () and light ends () coming from distillation are recycled to a compressor () and fed to a primary reformer (); further carbon dioxide can be recycled from the flue gas ().
