Abstract: A method for producing methanol or hydrocarbons is provided. The production method comprises producing a synthesis gas from carbonaceous material, according to a method comprising at least one reforming step, the synthesis gas having a first hydrogen/carbon monoxide molar ratio under the first operating conditions for the reforming operation; producing a stream of hydrogen from a hydrogenated raw material and from a first consumed electric power, the hydrogen stream having a first molar flow rate for said first consumed electric power; and lowering the consumed electric power for producing the hydrogen stream, down to a second electric power below the first electric power and transitioning to second operating conditions different from the first for the reforming operation in order to compensate for the lowering of the molar flow rate of the hydrogen flow, the synthesis gas having a second hydrogen/carbon monoxide molar ratio greater than the first under the second operating conditions.

Abstract: The invention relates to an equipment and a system for processing a gaseous mixture by permeation. The equipment of the invention includes m*n separation modules Pij, n and n being natural integers higher than or equal to 2, i being a natural integer from 1 to m, and j is a natural interger from 1 to n. Each of the separation modules P1 includes a permeate inlet Epij, the permeate inlet Ep11 of the separation module P11 corresponding to the F inlet for supplying the gaseous mixture into said equipment, a permeate outlet Spij and a retentate outlet Srij. Furthermore, the permeate outlet Spij is connected to the permeate inlet Epi+1j of the separation module Pj+1j, and the retentate outlet Srij is connected to the permeate inlet Epij+1 of the separation module Pij+1. The equipment does not use any intermediate recycling.
