Title: DEVICE AND METHOD FOR COGENERATION OF METHANOL AND SYNTHETIC METHANE
Abstract:
The device (200) for the cogeneration of methanol and synthetic methane comprises a device (100) for the hydrogenation of CO2 in order to produce methanol from a syngas comprising dihydrogen, H2, and carbon dioxide, CO2. It comprises: - a reactor (105) for the hydrogenation of CO2 in order to produce at least methanol, CH3OH or MeOH, referred to as "hydrogenation", - a first recirculation conduit (120), for recirculating at least a portion of the hot products from the hydrogenation reaction, connecting the reactor outlet to the reactor inlet, comprising a recirculator (125), - a means (130) for measuring the flow rate of syngas passing through the reactor inlet and - a means (135) for controlling the recirculator in order to control the recirculation of a quantity of hot products from the hydrogenation reaction determined according to the measured flow rate of syngas and a first predetermined setpoint value (140), and, the device (200) also comprises: an inlet (210) for a portion of the hydrogenation products comprising at least excess syngas following the hydrogenation reaction and an outlet (215) for methanation reaction products comprising at least synthetic methane.
