A method for separating carbon dioxide (CO) from a gas stream is disclosed, in which the gas stream is reacted with a lean aminosilicone solvent in an absorber, resulting in a rich aminosilicone solvent that is then treated in a desorber to release the COand regenerate lean aminosilicone solvent in a desorption reaction. The regenerated solvent is directed into a steam-producing, indirect heat exchanger that is configured to supply steam to the desorber at a temperature high enough to augment the desorption reaction. Also, selected amounts of make-up water are added to the rich aminosilicone solvent at one or more process locations between the absorber and the desorber, to lower the viscosity of the solvent and to lower the temperature required for the desorption reaction.

Method and system for treatment of a gas stream that contains carbon dioxide

A COenergy storage system includes a storage tank that stores a COslurry, including dry ice and liquid CO, at COtriple point temperature and pressure conditions. The storage system also includes a first pump coupled in flow communication with the storage tank. The first pump is configured to receive the COslurry from the storage tank and to increase a pressure of the COslurry to a pressure above the COtriple point pressure. The energy storage system further includes a contactor coupled in flow communication with the first pump. The contactor is configured to receive the high pressure COslurry from the pump and to receive a first flow of gaseous COat a pressure above the COtriple point pressure. The gaseous COis contacted and then condensed by the melting dry ice in the slurry to generate liquid CO.

Method and system for carbon dioxide energy storage in a power generation system

A power generation system includes a power generation plant portion including a feedwater heating system configured to channel a feedwater stream and a carbon dioxide capture portion coupled in flow communication with the power generation plant portion. The carbon dioxide capture portion includes a solvent circuit configured to channel a solvent stream through at least a portion of the carbon dioxide capture portion. The carbon dioxide capture portion also includes a heat recovery system coupled in flow communication with the solvent circuit and the feedwater heating system. The heat recovery system is configured to transfer heat energy from the solvent stream to the feedwater stream and to channel the heated feedwater from the heat recovery system to the feedwater heating system.

A method for treatment of a flue gas involves feeding the flue gas and a lean solvent to an absorber. The method further involves reacting the flue gas with the lean solvent within the absorber to generate a clean flue gas and a rich solvent. The method also involves feeding the clean flue gas from the absorber and water from a source, to a wash tower to separate a stripped portion of the lean solvent from the clean flue gas to generate a washed clean flue gas and a mixture of the water and the stripped portion of the lean solvent. The method further involves treating at least a portion of the mixture of the water and the stripped portion of the lean solvent via a separation system to separate the water from the stripped portion of the lean solvent.

The present invention is directed to aminosilicone solvent recovery methods and systems. The methods and systems disclosed herein may be used to recover aminosilicone solvent from a carbon dioxide containing vapor stream, for example, a vapor stream that leaves an aminosilicone solvent desorber apparatus. The methods and systems of the invention utilize a first condensation process at a temperature from about 80&#xb0; C. to about 150&#xb0; C. and a second condensation process at a temperature from about 5&#xb0; C. to about 75&#xb0; C. The first condensation process yields recovered aminosilicone solvent. The second condensation process yields water.

Aminosilicone solvent recovery methods and systems

A power generation system includes a fuel cell including an anode that generates a tail gas. The system also includes a hydrocarbon fuel reforming system that mixes a hydrocarbon fuel with the fuel cell tail gas and to convert the hydrocarbon fuel and fuel tail gas into a reformed fuel stream including CO. The reforming system further splits the reformed fuel stream into a first portion and a second portion. The system further includes a COremoval system coupled in flow communication with the reforming system. The system also includes a first reformed fuel path coupled to the reforming system. The first path channels the first portion of the reformed fuel stream to an anode inlet. The system further includes a second reformed fuel path coupled to the reforming system. The second path channels the second portion of the reformed fuel stream to the COremoval system.
