Abstract
Methods of reducing acid gas from a stream, comprising contacting the stream with a solvent system comprising a glycerol derivative are described herein. Disclosed herein is a composition comprising a glycerol derivative and an acid gas. A method for sweetening a natural gas stream comprising contacting a solvent system comprising a glycerol derivative with a natural gas stream is described herein.
Claims26
A method of reducing acid gas from a stream, comprising contacting the stream with a solvent system comprising a glycerol derivative, wherein the glycerol derivative has the following structure:
- wherein
- R1, R2 and R3 are independently selected from the group consisting of C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, cycloalkyl, aryl, thio, alkoxyl, aryloxyl, C2-20 fluoroalkyl, C2-C20 trifluoromethyl terminated alkyl, and C2-20 nitrile terminated alkyl, any of which is optionally substituted with one or more substituents selected from the group consisting of ether, C1-C5 alkyl, halogen, amine, and C1-C5 alkoxy;
- with the proviso that at least one of R1, R2, and R3 is not C(O)CH3.
A method for sweetening a natural gas feed stream, comprising contacting the natural gas feed stream, wherein the natural gas feed stream comprises acid gases, with a solvent system comprising a glycerol derivative, wherein the glycerol derivative has the following structure:
- wherein
- R1, R2 and R3 are independently selected from C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, cycloalkyl, aryl, thio, alkoxyl, aryloxyl, C2-20 fluoroalkyl, C2-C20 trifluoromethyl terminated alkyl, and C2-20 nitrile terminated alkyl, any of which is optionally substituted with one or more substituents selected from the group consisting of ether, C1-C5 alkyl, halogen, amine, and C1-c5 alkoxy;
- with the proviso that at least one of R1, R2, and R3 is not C(O)CH3.
