Abstract: A system and method for recovering a solvent from a decarbonated flue gas in an absorption column, the decarbonated flue gas having had carbon dioxide absorbed and removed by vapor-liquid contact with a carbon dioxide absorbing solution containing the solvent. The system includes an emission control section configured to bring a water stream substantially free of the solvent into contact with the decarbonated flue gas to recover the solvent from the decarbonated flue gas and to form a solvent containing wash water and a reduced solvent containing flue gas and a flue gas cooling section configured to bring cooled wash water into contact with the reduced solvent containing flue gas to cool the reduced solvent containing flue gas and condense water from the decarbonated flue gas thereby forming a cooled flue gas and used wash water.

Abstract: The present application relates to systems and processes for removal of gaseous contaminants from gas streams. In particular, the application relates to a process for removal of gaseous contaminants from a gas stream comprising contacting the gas stream with a wash solution to remove gaseous contaminants from the gas stream by absorption into the wash solution; and regenerating the used wash solution to remove gaseous contaminants from the used wash solution, to provide a regenerated wash solution and a gas comprising removed contaminants, wherein in a first regeneration stage the gas comprising removed contaminants is cooled to minimize loss of water vapor from the regeneration step.

Abstract: The present invention relates to a gas purification system for removal of acidic gases from a gas stream. The system comprises an absorption unit arranged for receiving a gas stream and contacting it with a wash solution stream and a cooling unit in fluid communication with the absorption unit. The cooling unit receives wash solution enriched with acidic gases from a first withdrawal level of said absorption unit, cools the enriched wash solution, and provides cooled, enriched wash solution to a first reintroduction level of the absorption unit upstream of the withdrawal level. The ratio of withdrawn wash solution is 10-90% of the total wash solution stream.

Abstract: A method and a system for controlling solvent emissions from a carbon capture unit includes passing solvent through a CO2 absorber and a flue gas effluent stream through the CO2 absorber and in a counter-current direction to the solvent passing through the CO2 absorber. Subsequently, a gas-phase effluent stream from the CO2 absorber is passed through an acid wash and the water wash to reduce an emission of solvent within a gas-phase effluent stream from the acid wash and a gas-phase effluent stream from the water wash. A control logic unit receives and processes a signal from a gas-phase analyzer and a pH sensor and passes a stream of acid wash and acid to the acid wash, and a stream of water wash to the water wash, via respective control valves.

Abstract: The present disclosure describes the efficient use of a catalyst, an enzyme for example, to provide suitable real cyclic capacity to a solvent otherwise limited by its ability to absorb and maintain a high concentration of CO2 captured from flue gas. This invention can apply to non-promoted as well as promoted solvents and to solvents with a broad range of enthalpy of reaction.

Abstract: The present invention relates processes of removal of acidic gases from a gas stream, comprising the steps of a) contacting a wash solution stream with said gas stream containing acidic gases to be removed to allow absorption of the acidic gases into the wash solution stream; b) withdrawing wash solution enriched with acidic gases from said wash solution stream at a first withdrawal level; c) cooling said withdrawn wash solution; and d) reintroducing said cooled wash solution to the wash solution stream at a first reintroduction level to form a mixed wash solution stream, said first reintroduction level being upstream of said first withdrawal level. The present invention also relates to systems for removal of acidic gases from a gas stream.

Abstract: An online monitoring and controlling system is used for monitoring and controlling sulfur content in heat stable salts or in a flue gas stream. The system comprises valves, sensors and analyzers that are operated by a valve flow and control system that regulates the valves to redirect flow of the heat stable salt or the flue gas stream to reduce the sulfur to below a desirable value. The valve and flow control system is automated and uses a feedback loop to control the sulfur content.
