Abstract: The invention relates to a methanol synthesis reactor for producing methanol from a synthesis gas mixture. The reactor according to the invention includes a pressure jacket having an interior in which a first and a second process unit are arranged one atop the other. Both process units are fluidically interconnected at least in respect of the process gases and configured as plate heat exchangers, preferably pillow plate heat exchangers. The plate interiors are traversable from bottom to top by cooling media while the plate interspaces are traversable from top to bottom by process gases, in particular synthesis gas and methanol-containing product streams. At least the first of the two process units has a methanol synthesis catalyst on the plate interspace side. The second process unit is used for cooling or further conversion of the product stream obtainable in the first process unit.

Abstract: The invention relates to an apparatus for separating a condensable reaction product from a process gas mixture. The apparatus includes a pressure jacket having an interior, wherein two process units are arranged one atop the other in the pressure jacket. The upper first process unit is configured for condensing the liquid reaction product from the process gas mixture and is thus in the form of a plate heat exchanger. The plate heat exchanger includes vertically arranged plates traversable by a cooling medium. The plates have plate interiors which are traversable by the cooling medium. Adjacent plates spaced apart from one another define plate interspaces which are traversable by the process gas mixture. The lower second process unit is configured for separating the reaction product condensed in the first process unit and is thus in the form of a gas-liquid separator.

Abstract: The invention relates to a reactor for performing exothermic equilibrium reactions, especially for producing methanol from synthesis gas in a multistage synthesis with intermediate condensation of the reaction product. The reactor according to the invention has a reactor shell and a multitude of series-connected and mutually fluid-connected reactor cells disposed within the reactor shell, where each of the reactor cells includes a reaction apparatus, a cooling-down apparatus and a phase separation apparatus as reactor cell elements. The reactor has a multitude of reactor planes disposed in a mutually parallel arrangement within the reactor shell, where reactor cell elements of the same kind are disposed in the same reactor plane. The inventive arrangement of the reactor cell elements enables the building of a compact reactor and reduces material stresses within the reactor by the avoidance of large temperature differences within the reactor shell.

Abstract: The invention relates to a process for aftertreatment of gas streams in which unwanted components are present in an amount that varies irregularly in a periodic manner or over time and/or in a varying concentration, by means of an absorption or gas scrubbing process. For this purpose, during the entry of the desorption peak into the gas scrubbing apparatus, the amount of scrubbing medium is increased proceeding from a normal value during a first phase and, after the end of the desorption peak, the amount of scrubbing medium is returned back to the normal value during a second phase, wherein the laden scrubbing media are collected in different intermediate vessels during the two phases, mixed and released as a mixture to a downstream scrubbing medium regeneration apparatus.
