TH49698A - Removing COS from the hydrocarbon fluid stream And liqueurs to remove impurities for use in this - Google Patents

Abstract

DC60 (06/01/53) This invention reveals a method for removing the COS from the fluid stream. Hydrocarboncias with COS is especially exiting the gas stream, for example natural gas, synthetic gas from concentrated oil or residual condensate. Or refinery gas, or from liquid hydrocarbons, or that are converted to liquids, for example, LPG (Liquefied Petroleum Gas) or NGL (Natural Gas Liquids). For use in the process As well This invention consists of conducting a fluid flow in an absorption band. Or extraction to touch the meat throughout the liqueur to eliminate impurities Which consists of substances Dissolves aqueous amines with aliphatic alkalamine with carbon from 2 to 12 atoms from 1.5 to 5 mol / l and with primary or secunda. oval The amines are also active, from 0.4 to 1.7 mol / L, which removes COS completely from this fluid stream. And separation of currents A fluid that has significantly removed the contaminant And the liquor removes impurities with this loaded COS and releases the fluid stream mentioned above. And the aforementioned liquor leaves this absorption or extraction bar. Subsequently, liquor may be removed to remove this impurity. Out by common methods And put it back into a new loop into the absorption or extraction bar. The invention discloses a method for removing COS from the hydrocarbonous flow that contains COS, especially from the gas stream, for example natural gas, synthetic gas from condensed oil or oil. Residue Or refinery gas Or from liquid hydrocarbons Or that is changed to a liquid, for example, LPG (Liquefied Petroleum Gas) or NGL (Natural Gas Liquids), and about the quarry removes impurities. For use in such processes as well This invention consists of conducting a fluid flow in an absorption band. Or extraction to touch the meat throughout the liqueur to eliminate impurities Which includes Aqueous amine solution containing aliphatic alkalamine with carbon from 2 to 12 atoms from 1.5 to 5 mol / L and with primary or secunda. oval The amines are also active, from 0.4 to 1.7 mol / L, which removes COS completely from this fluid stream. And separation of fluid flows that remove substances Mostly contaminated Significantly And the liquor removes impurities loaded with this COS. And release the flow of the said fluid And the said liqwar Out of the absorption bar Or this extraction Subsequently, the liquid may be removed to remove this impurity. Out by common methods And put it back into a new loop into the absorption or extraction bar.

Claims (3)
