摘要： Wet-type carbon dioxide capturing equipment includes a CO2 absorption tower where CO2 of an exhaust gas reacts with an absorbent, a CO2 stripping tower where CO2 is separated from a rich solution absorbed the CO2 in the CO2 absorption tower, a reboiler for supplying thermal energy to the CO2 stripping tower to separate the CO2 from the rich solution in the CO2 stripping tower, a first heat exchanger for heating the rich solution by exchanging heat between a lean solution having the CO2 separated therefrom in the CO2 stripping tower and the rich solution, a mechanical vapor recompressor (MVR) for compressing a CO2 gas separated in the CO2 stripping tower, and a second heat exchanger for separating a portion of CO2 from the rich solution by heating the rich solution by exchanging heat between the CO2 gas compressed in the MVR and the rich solution passing through the first heat exchanger, in which the rich solution having CO2 that is not separated in the second heat exchanger is input to the CO2 stripping tower where the CO2 is separated.

摘要： The present disclosure relates to a system for removing a pollutant from a power generation cycle that utilizes a high pressure circulating fluid. The system includes a first direct contact cooling tower configured to cool the high pressure circulating fluid and condense a fluid stream that removes SO2 from the circulating fluid. A first recirculating pump fluidly communicates with the first direct contact cooling tower. The first tower includes an outlet configured to circulate a cooled CO2 product stream, and a second direct contact cooling tower is configured to receive at least a portion of the cooled CO2 product stream from the outlet. The second direct contact cooling tower is configured to cool the CO2 product stream and condense a fluid stream that removes NOx from the CO2 product stream. A second recirculating pump fluidly communicates with the second tower. An associated method is provided.

摘要： An automatic tuning control system and method for controlling air pollution control systems such as a dry flue gas desulfurization system is described. The automatic tuning control system includes one or more PID controls and one or more supervisory MPC controller layers. The supervisory MPC controller layers are operable for control of an air pollution control system and operable for automatic tuning of the air pollution control systems using particle swarm optimization through simulation using one or more dynamic models, and through control system tuning of each of the PID controls, MPC controller layers and an integrated MPC/PID control design.

摘要： A method and apparatus for processing waste water generated during oilfield drilling operations with a mobile processing unit utilizing heat energy sourced from burning hydrocarbon fuel directly and/or capturing and using the exhaust heat energy generated by burning hydrocarbons in engines such as diesel engines in order to vaporize a dominant mass of the aqueous phase of the waste water while clarifying the heat source combustion gasses. The water vapor generated by the vaporization process may be discharged directly to the atmosphere or alternately condensed and captured for use as portable water. The residual waste water is thereby concentrated and the cost to dispose of the waste water is greatly reduced.

摘要： A process for cleaning process gas removes sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM) to produce a tail gas substantially free of these pollutants. The process oxidizes and absorbs SOx and NOx for storage as liquid acids. In some embodiments a PM removal stage and/or a SOx removal stage are provided in a close-coupled higher-pressure environment upstream from a turbocharger turbine. The process has example application in cleaning exhaust gases from industrial processes and large diesel engines such as ship engines.
