This disclosure relates to systems and methods for managing production and distribution of liquid water extracted from air. In certain embodiments, a system is provided that includes a plurality of local water generation units (110) including a first local water generation unit and a second local water generation unit. The first and second water generation units each include a controller that is configured to control a production rate of liquid water extracted from the air, a local water collection unit, and a local transceiver. A principal water supply unit (120) is in fluid communication with at least one of the local water collection units. The principal water supply unit is configured to store at least part of the liquid water extracted from the air and to maintain a principal water level at a reservoir of the principal water supply unit based on one or more operational parameters for water distribution.

A carbon dioxide recovery system includes: a plurality of absorption towers each disposed for each of a plurality of combustion equipments for absorbing carbon dioxide in an exhaust gas discharged from each of the plurality of combustion equipments into an absorption liquid by bringing the exhaust gas into contact with the absorption liquid; and at least one regeneration tower communicating with each of the plurality of absorption towers, for recovering carbon dioxide from a CO.sub.2 rich absorption liquid which is the absorption liquid flowing out of each of the plurality of absorption towers. The regeneration tower is smaller in number than the absorption towers.

The present disclosure provides systems and methods for nitric oxide (NO) generation and/or delivery. In some aspects, a nitric oxide generation system comprises a plasma chamber configured to ionize a reactant gas including nitrogen and oxygen to form a product gas that includes NO, a scrubber downstream from the plasma chamber and having a volume at least partially containing NO.sub.2 scrubbing material, and a flow controller downstream of the scrubber configured to control the flow of product gas from the scrubber to a delivery device. A pump is configured to convey product gas from the plasma chamber into the scrubber and is configured to pressurize the product gas in the scrubber when the flow controller is positioned to restrict the flow of product gas from the scrubber. The pressurized product gas accumulates within the scrubber and is at least partially scrubbed of NO.sub.2 prior to passage through the flow controller.

This invention relates to a method and a system of abating carbon dioxide (CO.sub.2) and/or hydrogen sulfide (H.sub.2S) in a geological reservoir. Water is pumped or transferred from a water source to an injection well. The gasses are merged with the water under conditions where the hydraulic pressure of the water is less than the pressure of CO.sub.2 and/or H.sub.2S gas at the merging point. The water with CO.sub.2 and/or H.sub.2S gas bubbles is transferred further downwardly at a certain velocity higher than the upward flow velocity of said CO.sub.2 and/or H.sub.2S gas bubbles ensuring downward movement of gas bubbles resulting in full dissolution of said CO.sub.2 and/or H.sub.2S in the water due to elevating pressure. The complete dissolution ensures a lowered pH of the water entering a geological (e.g. geothermal) reservoir which is needed to promote mineral reactions leading to CO.sub.2 and H.sub.2S abatement This abatement may be quantified by dissolving a tracer substance in a predetermined molar ratio to said dissolved CO.sub.2 and/or H.sub.2S and monitored in a monitoring well.

The invention relates to a process for aftertreatment of gas streams in which unwanted components are present in an amount that varies irregularly in a periodic manner or over time and/or in a varying concentration, by means of an absorption or gas scrubbing process. For this purpose, during the entry of the desorption peak into the gas scrubbing apparatus, the amount of scrubbing medium is increased proceeding from a normal value during a first phase and, after the end of the desorption peak, the amount of scrubbing medium is returned back to the normal value during a second phase, wherein the laden scrubbing media are collected in different intermediate vessels during the two phases, mixed and released as a mixture to a downstream scrubbing medium regeneration apparatus.

A system for scrubbing and monitoring H.sub.2S includes: a sample inlet valve that controls an input stream of the hydrocarbon gas from the gas canister; a first scrubber that removes a first portion of H.sub.2S from the input stream and that outputs a first stream with less H.sub.2S than the input stream; a second scrubber that removes a second portion of H.sub.2S from the first stream and that outputs a second stream with less H.sub.2S than the first stream; a H.sub.2S converter that converts all remaining H.sub.2S in the second stream into a di-ketone and that outputs an output stream with a concentration of the di-ketone; an optical detector that measures the concentration of the di-ketone in the output stream; and a processor that determines a concentration of H.sub.2S in the second stream based on the concentration of the di-ketone in the output stream.

A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing CO.sub.2 into an absorber; b) flowing the flue gas through an absorber having an absorbent with a water-lean solution having less than 50% water and one or more amines, with the absorbent capturing the CO.sub.2 and forming a reduced CO.sub.2 content gas having a baseline CO.sub.2 content; and c) washing the reduced CO.sub.2 content gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous CO.sub.2 into the wash solution. In this method, the washing removes the amines from the reduced CO.sub.2 content gas and produces a reduced amine content gas exiting from the wash column.

Provided is an exhaust gas treatment apparatus for ships including: a reaction tower supplied with exhaust gas containing particle matter and with liquid for treating the exhaust gas and configured to discharge exhausted liquid obtained by treating the exhaust gas; and a heating unit configured to heat discharged material containing the exhausted liquid to evaporate at least a part of moisture contained in the discharged material. The apparatus may further include a first storage unit configured to store first discharged material containing the particle matter removed from the exhausted liquid and a part of the exhausted liquid. The heating unit may heat the first storage unit. The apparatus may further include a second storage unit configured to store second discharged material containing the exhausted liquid from which at least a part of the particle matter has been removed. The heating unit may heat the second storage unit.

A turbocharger control system includes a turbine; a fluid source of a pressurized fluid; an input valve fluidly coupled between the fluid source and an input of the turbine; a bypass valve fluidly coupled between the fluid source and an output of the turbine; a rotating machine operatively coupled to the turbine and configured to move a working fluid; and a control system communicably coupled to the input valve and the bypass valve. The control system is configured to perform operations including determining a level of the pressurized fluid in the fluid source; determining at least one of a flow rate or a pressure of a working fluid moved by the rotating machine; and operating the input valve and the bypass valve to change an operating state of the turbine from a first operating state to a second operating state.

A method and modular desulfurization-decarbonization apparatus for removing contaminants from exhaust gas is described. The apparatus comprises discrete modular units with distinct functions. The modular units may be housed in standard shipping containers and installed on cargo ships. The modules can be removed and replaced while docking with minimal disruption to ship and port operations.
