摘要: The invention relates to a process and to a plant for producing methanol from a synthesis gas having a hydrogen deficit. A fresh gas stream from a reformer unit which includes hydrogen and carbon oxides is combined with a hydrogen-containing stream from a hydrogen recovery stage. This affords a synthesis gas stream having a stoichiometry number SN, defined as SN=[n(H2)−n(CO2)]/[n(CO)+n(CO2)], of less than 2.0. The synthesis gas stream is combined with a residual gas stream and the synthesis gas stream and the residual gas stream are passed through a bed of a methanol synthesis catalyst at elevated pressure and elevated temperature to obtain a product stream having methanol and the residual gas stream, and the product stream is cooled to separate methanol from the residual gas stream.

摘要: A bipolar plate for a fuel cell stack or for an electrolyzer stack, having an anode plate and a cathode plate which are joined to face-to-face. Wherein the face of the anode plate that faces the face of the cathode plate delimits an internal space that forms a circuit for the distribution of a first fluid, thereby forming a bipolar plate. Wherein the first opening and the second opening facing one another thereby forming a collector configured to enable the passage of the first fluid or a second fluid through the bipolar plate. Wherein the first opening and the second opening have distinct dimensions such the peripheral end of the first opening and the peripheral end of the second opening are offset in relation to one another in the plane of the bipolar plate, forming a shoulder at the peripheral end of the collector.

摘要: A method for fixing an assembly onto a gas vessel configured to contain a pressurized fluid. The assembly including a housing, an electronic acquisition board secured to the housing, and a strain gauge. The method including fixing the strain gauge to the vessel using a second adhesive means, the strain gauge being fixed to the vessel in such a way to allow deformation along with the vessel under the effect of the pressurized gas contained in the vessel. Electrically connecting the strain gauge and the electronic acquisition board using at least one electric cable thereby allowing the housing to be free to move relative to the strain gauge. Fixing the housing to the vessel using a first adhesive means so as to cover the strain gauge and thereby leaving a volume of air between the housing and the strain gauge and/or between the strain gauge and the electronic acquisition board.

摘要: A method for the use of a gaseous effluent containing a CO2 gas fraction and a non-CO2 gas fraction, including at a first location: providing liquid nitrogen at a temperature less than −196° C., and causing the gaseous effluent to contact the liquid nitrogen to as to capture at least part of the CO2 present in the CO2 gas fraction as a mixture of CO2 particles and liquid nitrogen. Conveying at least part of the mixture to a second location, and at the second location, bringing the mixture into contact with one or more ingredients of a wet concrete before and/or during and/or after the wet concrete is prepared by blending the ingredients of the wet concrete in a blender, so that the mixture extracts heat from said one or more ingredients of the wet concrete, and CO2 from the mixture partially carbonates Ca-compounds present in the wet concrete.
