14777269CARBONORO B.V.Johannes Petrus Aldegonda CUSTERS

A process capturing CO2 from a CO2-containing gas stream, contacting a CO2-containing gas stream with a CO2-absorbing agent in an absorption step in a vessel with maximum temperature T1 resulting in absorption of CO2. The CO2 absorbing agent comprising a polymer dissolved in an aqueous medium, the polymer, a thermoresponsive copolymer, comprising amine monomer distributed through the copolymer, subjecting the CO2-containing absorbing agent to a desorption step in a vessel with maximum temperature T2, releasing CO2, wherein T1 is below LCST of the thermoresponsive polymer at maximum CO2 loading, and T2 is above LCST of the thermoresponsive polymer at minimum CO2 loading. CO2 absorbing agent comprises amine component dissolved in the aqueous medium. Use of the specific polymer dissolved in an aqueous medium at T1, wherein amine monomer, distributed through the copolymer with an amine component, improves net CO2 sorption and high absorption speed, allowing a relatively small absorption reactor.

B01D 53/14
14814119WILLIAM MARSH RICE UNIVERSITYMichael S. WONG

An improved method of CO2 capture is described. Typically, CO2 is absorbed by an aqueous solution of amines at a first temperature to form a CO2-amine reaction product, and desorbed at a second higher temperature. The improvement described herein adds a catalyst to the CO2-amine reaction product in an amount such that the CO2 desorption occurs at a lower temperature than the second higher temperature.

PCT/US2014/049797DOW GLOBAL TECHNOLOGIES LLC MATTEUCCI, Scott T.
The present invention relates to a process for purification of a carbon dioxide feedstock, for example from a production well, which comprises carbon dioxide and gaseous and liquid C1+ hydrocarbons. Specifically, a carbon dioxide feedstream is passed through one or more separation unit wherein each separation unit removes one or more C1+ hydrocarbon from the carbon dioxide feedstream to provide a richer carbon dioxide gas stream. The process comprises one or more separation unit which employs an adsorption media and has an adsorption step and a media regeneration step wherein the regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process. One embodiment of this method provides for the use of a different regenerable adsorbent media in two or more separation units.
