Embodiment 1

[0089] Embodiment 1: Adsorption of hydrogen sulfide:

[0090] The test was carried out at room temperature and an equilibrium vapor pressure of 338 hPa. The beaded bottle was flushed with 120ml of hydrogen sulfide by using two needles. One needle is connected to a manometer with 1 hPa resolution. A needle was then used to inject 1 ml of TOMA-acetate, which was preheated with a blower to reduce viscosity, into the bottle. After stirring for 30 minutes using a magnetic stir bar, a constant pressure drop of 622 hPa was observed. This pressure drop corresponds to 0.26 mol at an equilibrium pressure of 338 hPa H2S / mol IL molar ratio. For comparison, a 30% aqueous solution of monoethanolamine under the same conditions provided a pressure drop of 651 hPa, which corresponds to an equilibrium pressure of 309 hPa of 0.11 mol H2S / mol L molar ratio.

Embodiment 2

[0091] Example 2: Adsorption of carbon dioxide:

[0092] The test was carried out at room temperature and an equilibrium vapor pressure of 523 hPa. Flush the bead bottle with 120ml of carbon dioxide by using two needles. One needle is connected to a manometer with 1 hPa resolution. Then 1 ml of TOMA-acetylacetonate, which was preheated with a blower to reduce the viscosity, was injected into the bottle using a needle. After stirring for 30 minutes using a magnetic stir bar, a constant pressure drop of 437 hPa was observed. This pressure drop corresponds to 0.18 mol at an equilibrium pressure of 523 hPa CO2 / mol IL molar ratio. For comparison, a 30% aqueous solution of monoethanolamine provides a pressure drop of 670 hPa under the same conditions, which corresponds to an equilibrium pressure of 290 hPa of 0.12 mol CO2 / mol L molar ratio.

Abstract

The method of use of an ionic liquid and device for sorption of a gas, specifically the invention is used for a device for sorption of a gas having an electric multipole moment and uses of ionic liquid for sorption of the gas. The invention is to provide a method and a device for removing gaseous or steamy components, which can save cost or be cheaper. In particular, the electric multipole moment may be an electric dipole moment and / or an electric quadrupole moment. The sorption may be an adsorption or an absorption. The ionic liquid may be a pure ionic liquid, i.e. a liquid substantially only containing anions and cations, while not containing other components, e.g. water. Alternatively a solution containing the ionic liquid and a solvent or further compound, e.g. water, may be used.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201080028274.1, the application date is June 22, 2010, and the invention title is "Ionic liquid for gas sorption and method of using the device". technical field [0002] The present invention relates to methods using ionic liquids, in particular for the sorption of gases or vapors with an electric multipole moment. Furthermore, the invention relates to devices for the sorption of gases or vapours. Background technique [0003] carbon dioxide (CO 2 ) is an undesirable diluent present in many gas sources. In order to improve the quality of the gas, the CO should be 2 removed to acceptable specifications. In the gas processing industry, different technologies have been used for the removal of CO 2 , including chemical solvents, physical solvents, and diaphragms. So far, chemical solvents (which are 2 reversible reaction) most commonly used to remove CO 2 ....
