Abstract: The invention relates to a process for producing methanol in which at least a portion of the obtained liquid raw methanol stream is decompressed to a decompression pressure in a liquid decompression apparatus, wherein the decompression pressure is lower than the synthesis pressure and wherein the liquid decompression apparatus does mechanical work. At least a portion of the mechanical work done by the liquid decompression apparatus is utilized to drive the synthesis gas compression apparatus required for compressing the synthesis gas to synthesis pressure. The utilization may be carried out indirectly, through generation of electrical energy, or directly through direct utilization of the mechanical work.

Abstract: A petroleum residue stream is heated and reacted with an oxygen stream and a carbon dioxide stream in a gasification unit to produce syngas. At least a portion of the carbon monoxide is converted into carbon dioxide to produce shifted syngas. At least a portion of the shifted syngas is separated to produce a syngas feed stream. At least a portion of the syngas feed stream is converted into methanol. At least a portion of the methanol is converted into one or more alkenes (olefins). At least a portion of the methanol is reacted with carbon monoxide to produce acetic acid. Carbon dioxide produced in the process can be recycled to the gasification unit to facilitate the production of the syngas.

Abstract: The disclosure relates to a plant, especially power plant, for reduction of the carbon dioxide content in atmospheric air, especially for improvement of atmospheric air quality. The plant has at least one electrolysis unit for oxygen production, at least one carbonization unit for carbon synthesis, especially a Bosch reaction unit, and at least one unit for cleaning of ambient air from an outside atmosphere surrounding the plant. The carbonization unit synthesizes carbon from carbon dioxide which is obtained from the atmosphere by means of the carbon dioxide sorption unit and this carbon is stored, in order to effectively reduce the proportion of carbon dioxide in the atmosphere. The disclosure further relates to a method of operating such a plant, with which the carbon dioxide content in the atmosphere can be efficiently reduced.
