    Abstract: The invention relates to a method for treating an H2S and CO2-containing fluid flow, wherein a) the fluid flow is treated with a first sub-flow (3.01) of a regenerated H2S-selective absorbent in a first absorber (A1) at a pressure of 10 to 150 bar, and a treated fluid flow (3.03) and an H2S-loaded absorbent (3.04) are obtained; b) the H2S-loaded absorbent is heated by means of an indirect heat exchange (3.07) with a regenerated H2S-selective absorbent (3.08); c) the heated H2S-loaded absorbent (3.09) is expanded to a pressure of 1.2 to 10 bar in a low-pressure expansion container (LPF), and a first CO2-enriched exhaust gas and a partially regenerated absorbent (3.11) are obtained; d) the partially regenerated absorbent (3.11) is regenerated in a desorption column (D), and an H2S-enriched exhaust gas (3.23) and a regenerated absorbent (3.08) are obtained; e) the H2S-enriched exhaust gas (3.23) is supplied to a Claus unit (CL), the exhaust gas of the Claus unit is supplied to a hydrogenation unit (HY), and a hydrogenated Claus final gas is obtained; f) the hydrogenated Claus final gas and the first CO2-enriched exhaust gas are treated with a second sub-flow (3.18) of the regenerated H2S-selective absorbent (3.17) in a second absorber (TGA) at a pressure of 1 to 4 bar, and a second CO2-enriched exhaust gas (3.25) and a second H2S-loaded absorbent (3.02) are obtained; and g) the second H2S-loaded absorbent is conducted into the first absorber (A1). The invention further relates to a system which is suitable for carrying out the method. The invention is characterized by a low energy requirement.

    Abstract: Bei einem Verfahren zur Diskriminierung von cis- und trans -1,3-Diaminocyclohexanen, setzt man ein Gemisch von cis- und trans -1,3-Diaminocyclohexanen mit Kohlendioxid oder einem reaktiven Kohlensäurederivat um und erhält selektiv den Harnstoff des cis- 1,3-Diaminocyclohexans, der durch ein mechanisches Trennverfahren abgetrennt werden kann. 4-Methylcyclohexan-1,3-diamin und/oder 2-Methylcyclohexan-1,3-diamin mit einem trans -Gehalt von 99 Mol-% oder mehr sind auf diese Weise erhältlich.

    Abstract: The invention relates to a method for removing hydrogen sulphide and carbon dioxide from a stream of fluid, the method comprising: a) an absorption step, in which the stream of fluid is brought into contact with an absorption agent comprising an aqueous solution (i) of an amine of general formula (I), where R
    1 , R
    2 and R
    3 are selected independently of one another from among C
    1-4 alkyl and C
    1-4 hydroxyalkyl; R
    4 in each case is independently selected from among hydrogen, C
    1-4 alkyl and C
    1-4 hydroxyalkyl; R
    5 in each case is selected from among hydrogen, C
    1-4 alkyl and C
    1-4 hydroxyalkyl; X represents OH or NH(CR
    1 R
    2 R
    3 ); m represents 2, 3, 4 or 5; n represents 2, 3, 4 or 5; and o represents 0 or 1; and optionally (ii) at least one tertiary amine, the molar ratio of (i) to (ii) is greater than 0.05; wherein at least 90% of the hydrogen sulphide is removed from the stream of fluid, the selectivity for hydrogen sulphide in relation to carbon dioxide is no greater than 8 and a CO
    2 - and H
    2 S-loaded absorbent agent is thus obtained; b) a regeneration step, in which at least one sub-stream of the CO
    2 - and H
    2 S-loaded absorption agent is regenerated and a regenerated absorption agent is thus obtained; and c) a recirculation step, in which at least one sub-stream of the regenerated absorption agent is recirculated to the absorption step a). The method permits a high degree of separation of the hydrogen sulphide with a simultaneously high coabsorption of carbon dioxide.
