    Abstract: An absorbent for selective removal of hydrogen sulfide over carbon dioxide from a fluid stream comprises an aqueous solution of a) a tertiary amine, b) a sterically hindered secondary amine of the general formula (I) in which R1 and R2 are each independently selected from C1-4-alkyl and C1-4-hydroxyalkyl; R3, R4, R5 and R6 are each independently selected from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, with the proviso that at least one R4 and/or R5 radical on the carbon atom bonded directly to the nitrogen atom is C1-4-alkyl or C1-4-hydroxyalkyl when R3 is hydrogen; x and y are integers from 2 to 4 and z is an integer from 1 to 4; where the molar ratio of b) to a) is in the range from 0.05 to 1.0, and c) an acid in an amount, calculated as neutralization equivalent relative to the protonatable nitrogen atoms in a) and b), of 0.05 to 15.0%. One preferred amine of the formula I is 2-(2-tert-butylaminoethoxy)ethanol. The absorbent allows a defined H2S selectivity to be set at pressures of the kind typical in natural gas processing.

    Abstract: In a process for removing CO2 from a fluid stream by means of an aqueous absorption medium, a) the fluid stream is introduced into a first absorption zone and treated with partially regenerated absorption medium, b) the treated fluid stream is treated with regenerated absorption medium in a second absorption zone, giving a fluid stream which has been freed of CO2 and a loaded absorption medium, c) the loaded absorption medium is depressurized in a first flash vessel to a pressure of from 1.2 to 3 bar absolute, giving a sub-partially regenerated absorption medium and a first CO2-comprising gas stream, d) the sub-partially regenerated absorption medium is depressurized in a second flash vessel to a pressure of from 1 to 1.2 bar absolute, giving a partially regenerated absorption medium and a water vapor-comprising, second CO2-comprising gas stream, e) a substream of the partially regenerated absorption medium is fed into the first absorption zone and a further substream of the partially regenerated absorption medium is fed into a stripper in which the partially regenerated absorption medium is thermally regenerated, with regenerated absorption medium and a third CO2-comprising gas stream being obtained and the stripper being operated at a pressure which is at least 0.9 bar higher than the pressure in the first flash vessel, f) the regenerated absorption medium is recirculated to the second absorption zone, g) the water vapor-comprising, second CO2-comprising gas stream is compressed by means of a jet pump and brought into direct heat exchange contact with the loaded absorption medium in the first flash vessel, with the jet pump being operated by means of the third CO2-comprising gas stream. The latent heat of the water vapor-comprising gas streams remains in the process and the use of a costly compressor is dispensable.

    Abstract: A process for preparing methanol from a carbon-containing feedstock by producing synthesis gas therefrom in a synthesis gas production unit, converting the synthesis gas to methanol in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon monoxide, carbon dioxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol are combusted with an oxygenous gas, and the carbon dioxide in the resultant flue gas is separated off in a carbon dioxide recovery unit and recycled to the synthesis gas production unit and/or to the methanol synthesis unit.

    Abstract: Disclosed herein are a communication system, a monitoring system for in-situ monitoring of a substance used in a gas scrubbing process, and related methods. The monitoring system can be used to monitor the at least one substance and provide treatment data for treating the at least one substance. The communication system includes a cloud server, a first server, a second server, and a third server. The first and second servers respectively include first and second communication interfaces configured to provide spectral information to the cloud server.
    The cloud server is configured to generate a calibration model including at least one parameter; apply the calibration model to the spectral information provided by the second server, whereby at least one value for the at least one parameter is extracted; and provide the at least one value for the at least one parameter to the first server via the first communication interface.

    Abstract: A process for removing C5-C8-hydrocarbons and acid gases from a fluid stream is described, where a) the fluid stream is brought into contact with an absorption medium comprising at least one amine in an absorption zone to obtain a deacidified fluid stream and an acid-gases-laden absorption medium, b) the laden absorption medium is heated in a first heat exchanger and decompressed into a decompression zone to a pressure of from 5 to 10 bar to obtain a C5-C8-hydrocarbons-comprising gas phase and a hydrocarbon-depleted laden absorption medium, c) the hydrocarbon-depleted laden absorption medium is heated in an optional second heat exchanger and passed into a stripper in which at a pressure of 1 to 2.5 bar the acid gases are at least partially liberated by supplying heat to obtain a regenerated absorption medium and an acid-gas-comprising stream, and d) the regenerated absorption medium is recycled into the absorption zone.
