Definitions
- Various amine solutions have been used for the removal of acidic gases from gases and liquids.
- Common acidic gases may include, C0 2 , H 2 S, CS 2 , HCN, COS and oxygen and sulfur derivatives of Ci to C 4 hydrocarbons.
- the treatment of gases and liquids containing acidic gases, such as C0 2 and H 2 S, with certain amine solutions typically results in the simultaneous removal of substantial amounts of both C0 2 and H 2 S.
- Selective removal of H 2 S results in a relatively high H 2 S/C0 2 ratio in the separated acid gas, which may aid in the conversion of H 2 S to elemental sulfur using the Claus process.
- the present disclosure provides an amine composition comprising a mixture of at least two sterically hindered amines comprising a first amine with the formula:
- the present disclosure provides a method of making an amine composition
- a method of making an amine composition comprising reacting a polyethylene glycol with a tertiarybutylamine in the presence of a nickel-based hydrogenation catalyst to form an amine composition comprising a mixture of at least two sterically hindered amines, wherein the amine composition comprises at least a first amine with the formula:
- the present disclosure provides a method comprising contacting a gaseous stream comprising sulfur-containing compounds with an amine composition comprising a mixture of at least two sterically hindered amines, wherein the amine composition comprises at least a first amine with the formula:
- Figure 1 is a graph showing the effect of C0 2 concentration on H 2 S removal.
- Figure 2 is a graph showing the effect of C0 2 concentration effect on C0 2 absorption.
- Figure 3 is a graph showing the change of H 2 S in a treated gas as a function of the amine circulation rate.
- the present disclosure generally relates to sterically hindered amines, and more specifically, to the production of sterically hindered amines from polyethylene glycol and tertiarybutylamine and their use in acidic gas removal.
- the present disclosure is based, at least in part, on the observation that under certain conditions, such as C0 2 rich conditions and/or high bis-(tertiarybutylaminoethoxy) ethane content, certain amines for selectively removing H 2 S gas may become phase separated.
- certain amines for selectively removing H 2 S gas may become phase separated.
- the present disclosure addresses this problem by, among other things, reacting a higher molecular weight polyethylene glycol with a tertiarybutylamine to produce a mixture of sterically hindered amines that provides good performance without the problem of phase separation.
- the sterically hindered amines of the present disclosure may be made without the need for a solvent, thereby simplifying their production.
- the methods of the present disclosure may be considered more "environmentally friendly" in that they produce higher yields of desirable amine products with minimal to no production of undesirable by-products, which may also reduce the costs associated with making sterically hindered amines.
- the present disclosure provides an amine composition comprising a mixture of at least two sterically hindered amines with the following formulas:
- the weight ratio of a first sterically hindered amine (1) to a second sterically hindered amine (2) is about 2.5:1 to about 6: 1. In some embodiments, the weight ratio of a first sterically hindered amine (1) to a second sterically hindered amine (2) is about 4: 1.
- an amine composition of the present disclosure may comprise a mixture of at least two sterically hindered amines, a first sterically hindered amine having the chemical formula shown in (1) wherein x is an integer ranging from 7 to 14; and a second sterically hindered amine having the chemical formula shown in (2) wherein y is an integer ranging from 7 to 14.
- the present disclosure also provides methods of making these amine compositions comprising reacting a polyethylene glycol with a tertiarybutylamine in the presence of a nickel-based hydrogenation catalyst.
- the polyethylene glycol suitable for use in the present disclosure generally has a molecular weight between about 180 to about 1000 grams per mole (g/mol). In some specific embodiments, the polyethylene glycol may have a molecular weight between about 180 to about 400 g/mol. In some specific embodiments, the polyethylene glycol may have a molecular weight between about 200 to about 300 g/mol.
- Nickel-based hydrogenation catalysts suitable for use in the present disclosure may include any nickel based catalyst capable of catalyzing a reaction between polyethylene glycol and a tertiarybutyl amine.
- a suitable hydrogenation catalyst comprises those nickel-based catalysts disclosed in U.S. Patent Nos. 7,683,007 and 7,196,033, both of which are hereby incorporated by reference in their entirety.
- the hydrogenation catalyst may be in any suitable form, including but not limited to, pellets, tablets, extrudates, spheres, etc.
- a suitable catalyst can either be unsupported or deposited on a support material, as is known to those skilled in the art, such as alumina, silica, etc.
- reduction of the hydrogenation catalyst may be carried out in situ while conducting the process by the presence of hydrogen. Hydrogen, however, is not essential to conducting the process but may be employed, for example, to minimize catalyst deactivation.
- the sterically hindered amines of the present disclosure may be made without the need for a solvent, thereby simplifying their production.
- an inert solvent may be included in the reaction medium if desired. Examples of suitable solvents may include, but are not limited to, a cyclic or linear ether or a hydrocarbon containing compound in which the reactants will dissolve.
- the amination process may be carried out in any suitable reactor, including, but not limited to, a fixed-bed reactor, a fluid-bed reactor, a continuous stirred reactor, or a batch reactor.
- the reaction of polyethylene glycol with a tertiarybutylamine may be carried out in a reactor under a pressure of about 500 to about 3000 psig and a temperature of from about 160°C to about 240 °C.
- the sterically hindered amines of the present disclosure may be placed in a liquid medium prior to use, such as water, an organic solvent and mixtures thereof.
- the sterically hindered amines may also be used in conjunction with a wide range of additives typically employed in selective gas removal processes, such as anti-foaming agents, antioxidants, corrosion inhibitors, etc. in an effective amount.
- the sterically hindered amines of the present disclosure may also be used in conjunction with a strong acid, such as sulfuric acid, sulfurous acid, phosphoric acid, phosphorous acid, pyrophosphoric acid, acetic acid, formic acid, adipic acid, benzoic acid, etc.
- Acidic gas mixtures suitable for use in the present disclosure include any gas mixture that comprises an acidic gas for which acid gas removal is desired.
- suitable acidic gas mixtures are those comprising H 2 S, and optionally other gases such as C0 2 , N 2 , CH 4 , H 2 , CO, COS, HCN, C 2 H 4 , NH 3 , etc.
- Acidic gas mixtures may include various types of gases, including, but not limited to, combustion gases, refinery gases, town gas, natural gas, syn gas, water gas, propane, propylene, heavy hydrocarbon gases, etc.
- the present disclosure also provides a method for removing sulfur-containing compounds from a gaseous stream comprising contacting the gaseous stream with an amine composition of the present disclosure.
- the gaseous stream and an amine composition of the present disclosure may be brought into contact using any conventional means, such as a tower or packed vessel.
- a gaseous stream may be fed into a lower portion of an absorption tower while an amine composition of the present disclosure is fed into an upper portion of the tower.
- the gaseous stream and the amine composition may come into contact with each other such that sulfur- containing compounds, such as H 2 S, may be selectively absorbed by the amine composition.
- the amine composition containing the selectively absorbed sulfur-containing compounds may then emerge near the bottom or lower portion of the tower, which the remaining normally gaseous stream, emerges from the upper portion of the tower.
- the amine composition containing the sulfur-containing compounds may be at least partially regenerated so that it may be reused.
- PEG-240 from Example 1 and tertiarybutylamine were each continuously fed to a tubular reactor that was charged with 250 cc of a nickel catalyst at feed rates of 120 g/hr and 300 g/hr, respectively.
- the reactor pressure and temperature (hot oil temperature) were maintained at 2000 psig and 200°C.
- the reactor effluent was stripped of excess tertiarybutylamine and other light materials.
- the resulting product was analyzed to contain 4.28 meq/g of total amine.
- Example 3 Preparation of Amine from TEG [0029] Triethylene Glycol and tertiarybutylamine were each continuously fed to a tubular reactor that was charged with 250 cc of a nickel catalyst at feed rates of 115 g/hr and 300 g/hr, respectively. The reactor pressure and temperature (hot oil temperature) were maintained at 2000 psig and 200°C. The reactor effluent was stripped of excess tertiarybutylamine and other light materials. The resulting product was analyzed to contain 5.72 meq/g of total amine.
