    Abstract: THE DISCLOSURE CONCERNS A PROCESS FOR REMOVING MERCAPTANS FROM FLUID STREAMS COMPRISING SAME , ESPECIALLY FROM HYDROCARBON GAS STREAMS, FOR EXAMPLE NATURAL GAS , SYNTHESIS GAS FROM HEAVY OIL OR HEAVY RESIDUES OR REFINERY GAS , OR ELSE FROM LIQUID HYDROCARBONS, FOR EXAMPLE LPG (LIQUEFIED PETROLEUM GAS ). THE INVENTION COMPRISES INTIMATELY CONTACTING THE FLUID STREAM IN AN ABSORPTION OR EXTRACTION ZONE WITH A SCRUBBING LIQUOR COMPRISING AT LEAST ONE ALIPHATIC ALKANOLAMINE OF 2-12 CARBON ATOMS , THE AMOUNT OF WASH LIQUOR BEING SUPPLIED TO THE ABSORPTION OR EXTRACTION ZONE BEING SUFFICIENT TO REMOVE AT LEAST CO2 AND H2S ESSENTIALLY COMPLETELY FROM THE FLUID STREAM , AND SEPARATING THE SUBSTANTIALLY DECONTAMINATED FLUID STREAM AND THE CONTAMINATED WASH LIQUOR AND DISCHARGING THEM FROM THE ABSORPTION ZONE . THE SUBSTANTIALLY COMPLETE REMOVAL OF CO2 AND H2S IS ACCOMPANIED BY THE REMOVAL FROM THE GAS STREAM OF A VERY LARGE PORTION OF THE MERCAPTANS AS WELL , WITHOUT A SIGNIFICANT FRACTION OF THE HYDROCARBON GASES DISSOLVING IN THE WASH LIQUOR.

    Abstract: A process for preparing xylylenediamine, comprising the steps of ammoxidizing xylene to phthalonitrile and hydrogenating the phthalonitrile, which comprises contacting the vaporous product of the ammoxidation stage directly with a liquid organic solvent or with molten phthalonitrile (quench), partly or fully removing components having a boiling point lower than phthalonitrile (low boilers) from the resulting quench solution or suspension or phthalonitrile melt and, after the low boiler removal and before the hydrogenation, removing products having a boiling point higher than phthalonitrile (high boilers).

    Abstract: In a process for deacidifying a fluid hydrocarbon stream which comprises carbon dioxide (CO 2 ) and/or other acid gases as impurities, the fluid stream is brought into intimate contact with an absorption liquid in an absorption or extraction zone ( 12 ), the substantially purified fluid stream and the absorption liquid which is loaded with CO 2 and/or other acid gases are separated from one another, and the absorption liquid is subsequently regenerated and then again fed to the absorption extraction zone ( 12 ). To regenerate the absorption liquid, the loaded absorption liquid is first expanded in a first low-pressure expansion stage ( 22 ) to a pressure of from 1 to 2 bar (absolute). The partially regenerated absorption liquid is then heated in a heat exchanger ( 20 ) and then, in a second low-pressure expansion stage ( 29 ), again expanded to a pressure of from 1 to 2 bar (absolute).

    Abstract: COS is selectively removed with respect to CO2 from a hydrocarbonaceous fluid stream which contains CO2 and COS. Examples of the fluid stream include a gas stream, for example natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or from liquid or liquefied hydrocarbons, for example LPG (Liquefied Petroleum Gas) or NGL (Natural Gas Liquids). The process is carried out by (1) intimately contacting the fluid stream in an absorption or extraction zone with a scrubbing liquor consisting of an aqueous amine solution containing from 1.5 to 5 mol/l of an aliphatic alkanolamine having of from 2 to 12 carbon atoms and from 0.8 to 1.7 mol/l of at least one activator selected from the group consisting of piperazine, methyl piperazine and morpholine, (2) removing the COS essentially completely from the fluid stream, and (3) separating the substantially COS-decontaminated fluid stream and the COS-loaded scrubbing liquor and discharging them from the absorption or extraction zone.

    Abstract: The disclosure concerns a process for removing mercaptans from fluid streams comprising same, especially from hydrocarbon gas streams, for example natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or else from liquid hydrocarbons, for example LPG (liquefied petroleum gas). The invention comprises intimately contacting the fluid stream in an absorption or extraction zone with a scrubbing liquor comprising at least one aliphatic alkanolamine of 2-12 carbon atoms, the amount of wash liquor being supplied to the absorption or extraction zone being sufficient to remove at least CO2 and H2S essentially completely from the fluid stream, and separating the substantially decontaminated fluid stream and the contaminated wash liquor and discharging them from the absorption zone. The substantially complete removal of CO2 and H2S is accompanied by the removal from the gas, stream of a very large portion of the mercaptans as well, without a significant fraction of the hydrocarbon gases dissolving in the wash liquor.

    Abstract: CAS IS SELECTIVELY REMOVED WITH RESPECT TO CO2 FROM A HYDROCARBONACEOUS FLUID STREAM WHICH CONTAINS CO2 AND CAS. EXAMPLES OF THE FLUID STREAM INCLUDE A GAS STREAM, FOR EXAMPLE NATURAL GAS, SYNTHESIS GAS FROM HEAVY OIL OR HEAVY RESIDUES OR REFINERY GAS, OR FROM LIQUID OR LIQUEFIED HYDROCARBONS, FOR EXAMPLE LPG (LIQUEFIED PETROLEUM GAS) OR NGL (NATURAL GAS LIQUIDS). THE PROCESS IS CARRIED OUT BY (1) INTIMATELY CONTACTING THE FLUID STREAM IN AN ABSORPTION OR EXTRACTION ZONE (12) WITH A SCRUBBING LIQUOR CONSISTING OF AN AQUEOUS AMINE SOLUTION CONTAINING FROM 1.5 TO 5 MOL/L OF AN ALIPHATIC ALKANOLAMINE HAVING OF FROM 2 TO 12 CARBON ATOMS AND FROM 0.8 TO 1.7 MOL/L OF AT LEAST ONE ACTIVATOR SELECTED FROM THE GROUP CONSISTING OF PIPERAZINE, METHYL PIPERAZINE AND MORPHO LINE, (2) REMOVING THE CAS ESSENTIALLY COMPLETELY FROM THE FLUID STREAM, AND (3) SEPARATING THE SUBSTANTIALLY COS-DECONTAMINATED FLUID STREAM AND THE CAS-LOADED SCRUBBING LIQUOR AND DISCHARGING THEM FROM THE ABSORPTION OR EXTRACTION ZONE (12).FIG. 1
