Abstract: Disclosed herein are methods for CO2 capture that use phase change ionic liquids (PCILs) to remove the CO2 from flue gas or other gas streams containing CO2. PCILs have high CO2 uptake and form a liquid PCIL-CO2 complex when they react with C( )2. When the liquid PCIL-CO2 complex is heated to regenerate the solid PCIL material by removing the carbon dioxide, part of the heat needed to release the CO2 can be supplied by the heat of fusion of the PCIL as it solidifies. Utilization of the heat of fusion of the PCIL to assist in its own regeneration can substantially reduce the parasitic energy loss associated with post-combustion CO2 capture.

Abstract: A method and device for the reduction of particulate forming vapors in gases, the method comprising passing the gas stream through at least one channel (12) that has a wall temperature that is lower than the condensation temperature of the vapor, the at least one channel having a hydraulic diameter (Dh) satisfying the condition that Dh<[24/(N?do)]1/2, where N is the number of nuclei present in the gas stream and do is the initial diameter of the nuclei.

Abstract: A process for separating a gas mixture in a separation unit of the type in which the gas mixture comes from a reaction unit and comprises, as main constituents, hydrogen (H2) and/or carbon monoxide (CO).

Abstract: A method of separating/purifying a gas mixture (M), includes a step consisting in capturing at least one gas which can generate anionic species by dissolution in aqueous phase. The invention is characterised in that it also includes the following steps consisting in: suspending an absorbent product in the aforementioned aqueous phase, the absorbent product consisting of a lamellar double hydroxide or a mixed oxide which is believed to be amorphous and which originates from the moderate heat treatment of lamellar double hydroxides having an affinity for the above-mentioned gas; distributing the gas mixture (M) in the aqueous phase; and recovering the adsorbate from the absorbent product in suspension.

Abstract: A method and an equipment for improving global warming and air pollution are proposed, wherein hot exhaust gas generated by a thermal machine is injected into an exhaust boosting unit to be compressed and mixed with a liquid medium for atomization. Pollutants in the hot exhaust gas and heat generated due to combustion are adsorbed by the liquid medium. After the liquid medium passes a dust collecting unit, the pollutants adsorbed by the liquid medium will adhere to the dust collecting unit. Humid and hot clean air is extracted to the atmosphere, and rises to high altitudes and is cooled there. Water will drop to the ground in the form or rain or snow to cool the ground temperature and remove other pollutants in the air. Heat circulation and water circulation can be sped up to improve the situation of global warming and render more water resource to the Earth.

Abstract: A method of and an apparatus for capturing CO2 from flue gas emanating from a carbonaceous fuel combusting power plant, which includes a source of oxygen and a combustion chamber for combusting the fuel with oxygen and thereby producing flue gas that includes CO2, water and excess oxygen as its main components. At least a portion of the flue gas is compressed to a pressure higher than about sixty bar, the compressed flue gas is cooled in a primary CO2 separating unit for capturing a first portion of the CO2 by condensing it to produce a liquid CO2 stream and a high pressure vent gas stream that includes oxygen and excess CO2, the liquid CO2 stream is discharged from the power plant, and the high pressure vent gas stream is conducted to a secondary CO2 separating unit for capturing a second portion of the CO2 by adsorbing it to an adsorbing material.

Abstract: An apparatus removes water from a liquid mixture which has formed in a compressed gas system. The apparatus includes a gas compressor having an inlet port for receiving low pressure gas to be compressed and a discharge port through which a stream of compressed gas flows. An aftercooler is disposed in fluid communication with the discharge port for cooling the compressed gas stream. A vessel collects any entrained liquid water and lubricant from the compressed gas stream. The vessel has a sump portion and a vent to an atmosphere external to the compressed air system. A heat exchanger heats the liquid mixture within the vessel to a predetermined temperature to vaporize the water. The water vapor exits the vessel through the vent and the lubricant remains in the sump portion of the vessel. A valve permits the separated lubricant to be drained from the sump portion of the vessel to a location external to the compressed air system.
