摘要: A method comprising the steps of:
a) capturing carbon dioxide in a carbon dioxide absorption unit using a carbon dioxide absorption solution;
b) feeding the carbon dioxide absorption solution comprising absorbed carbon dioxide and generated in step a) to the high-pressure regenerator of a heat exchange system comprising the high-pressure regenerator and a steam-fired reboiler; and
c) supplying low-pressure steam at a pressure ranging from 3.2 to 3.5 kg/cm2 to the steam-fired reboiler for supplying heat to the high-pressure regenerator wherein, the carbon dioxide absorption solution is heated, thereby producing a steam condensate and a regenerated carbon dioxide absorption solution;
characterized in that the method further comprises the step of:
d) directly supplying the steam condensate produced in step c) to a de-aerator, thereby producing an aqueous solution suitable for producing steam with an oxygen content lower than 20 ppb.-

摘要: Systems and methods for separation of a component from a mixed gas stream by a combination of direct contact heat and material exchange in an indirect contact heat exchanger are disclosed. A contact liquid stream wets an interior surface of the process channel of the indirect contact heat exchanger and the mixed gas stream passes through the process channel, contacting the contact liquid stream for heat and mass exchange. A refrigerant in the refrigerant channel of the indirect contact heat exchanger and a depleted gas stream in a depleted gas stream channel are used for heat exchange with the contact liquid.

摘要: Integrated Energy Systems (IESs), such as for use in capturing atmospheric carbon dioxide, and associated devices and methods are described herein. A representative IES can include a power plant system having multiple modular nuclear reactors, a desalination plant, a brine processing plant, and a direct air capture plant. The nuclear reactors can generate electricity and/or steam for use by the desalination plant and the direct air capture plant. The desalination plant can use the electricity and/or steam to produce brine from seawater or brackish water. The brine processing plant can receive the brine from the desalination plant and process the brine to produce sodium hydroxide. The direct air capture plant can use the sodium hydroxide as a liquid sorbent in a direct air capture process to capture carbon dioxide from atmospheric air.

摘要: Systems and methods for controlling an amine contactor are provided. An exemplary method includes determining a pickup ratio for a solvent in the contactor, measuring a temperature of a lower tray of the contactor, adjusting the pickup ratio based, at least in part, on the temperature, and adjusting a flow rate for an injection of lean solvent into the contactor based, at least in part, on the pickup ratio.
