Embodiments of the present disclosure include a system, method, and apparatus comprising a large scale direct steam generator operating on an oxidant of air or enriched air configured to generate steam and combustion exhaust constituents. An exhaust constituent separation system and an energy recovery system to reclaim energy and improve the efficiency of the thermodynamic cycle. An optional CO2 separation system and Non Condensable Gas injection system may be included.

A multi-functional composition of matter that is useful for injection into a flue gas stream to rapidly and efficiently remove mercury from the flue gas streams, particularly at above average flue stream temperatures of about 340° F. or higher. The multi-functional composition of matter may include a fixed carbon content of at least about 20 wt. %, a mineral content of from about 20 wt. % to about 50 wt. %, a sum of micropore plus mesopore volume of at least about 0.20 cc/g, a micropore volume to mesopore volume ratio of at least about 0.7, and a tapped density of not greater than about 0.575 g/ml. These compositions may be further characterized by number of particles per gram of the composition of matter such that the composition may have at least about 0.8 billion particles per gram, or even as many as 1.5 billion particles per gram. These physical and chemical properties may enhance (1) the oxidation reaction kinetics for the oxidation of mercury species, (2) frequency of contact events, and (3) capture and sequestration of mercury, to achieve efficient mercury capture by the composition even in high temperature flue gas streams.

A process for discharging high-temperature flue gas safely from an ocean platform includes discharging the gas from combustion facilities into a main body of a cooling and cleaning device through an exhaust pipe, while sea water is injected into the main body. The injected water passes through a water distributor located at an upper part, and the scrubbing sea water is sprayed downwards. The high-temperature flue gas enters into a lower part, and the gas is scrubbed by the sprayed sea water to be low-temperature clean flue gas. The low-temperature clean flue gas passes through the water distributor and a mist eliminator, and is discharged into atmosphere through an outlet at a top of the main body. The sea water is collected to a liquid pool located at a lower part of the main body and discharged into the ocean. A cooling and cleaning device is also disclosed.

A wet abatement system which can suppress the accumulation of foreign matters in a treatment gas line is proposed. There is provided a wet abatement system for detoxifying treatment gas by bringing the treatment gas into contact with liquid. The wet abatement system includes an inlet casing having an inlet port from which the treatment gas is let in and an outlet port provided below the inlet port and through which the treatment gas flows, and a liquid film forming device provided between the inlet port and the outlet port and configured to form a liquid film on an inner wall surface of the inlet casing. A heater configured to heat the inlet casing is embedded in an interior of a wall portion of the inlet casing, the wall portion constituting a portion situated above the liquid film forming device.

A plant for the absorption of individual components, such as pollutants or recyclable materials, in gases, in which an absorption solution is brought into contact with the gas in an absorption chamber, where the absorption solution is fed into the absorption chamber through spray nozzles and the gas can be fed into the absorption chamber from below through a vertical inlet duct, where the inlet duct is covered by a roof structure. The roof structure is made up of a large number of lamellae placed one on top of one another and with spaces in between.

An exhaust gas treatment device includes an exhaust gas line where a combustion exhaust gas discharged from a power generation facility flows through, an exhaust gas line where a second combustion exhaust gas discharged from a second power generation facility flows through, exhaust gas exhaust line disposed by branching off from exhaust gas line, discharging a part of combustion exhaust gases as exhaust combustion exhaust gases, a nitrogen oxide removing unit removing nitrogen oxide contained in an integrated combustion exhaust gas that integrates the combustion exhaust gases, an integrated waste heat recovery boiler recovering waste heat from the integrated combustion exhaust gas, and a CO.sub.2 recovery unit recovering CO.sub.2 contained in the integrated combustion exhaust gas by using CO.sub.2 absorbing liquid.

The present invention discloses an apparatus (100), for scrubbing smoke comprising: a first tank (110), having a compartment (111), filled with a liquid; and, an inlet (112), configured to draw in the smoke into the compartment (111) from a combustion source, characterized in that, the first tank (110) includes a propeller system (113), arranged within the compartment (111) to mix the smoke with the liquid, for providing first scrubbing effect by propelling the liquid.

The present invention relates to a method and to an apparatus for separating an exhaust gas, in particular an exhaust gas of a boiler, comprising introducing a gas stream of exhaust gas inside a washing chamber, dispensing a pressurized liquid shaped as drops inside the washing chamber, wherein the delivery pressure is adjusted according to the specific particulate to be separated so as to provide, during the separating step, a physical interaction between the delivered liquid drops and the particulate particles.

This disclosure relates to a process for steam plume suppression. The process involves using thermosyphon shell and tube heat exchangers to cool a hot gas stream, using a wet scrubber to clean the cooled hot gas stream and generate a wet gas comprising water vapor, and using thermosyphon shell and tube heat exchangers to heat the wet gas above the dew point. This disclosure also relates to a steam plume suppression system. The system involves thermosyphon shell and tube heat exchangers and a wet scrubber.

The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for reducing and/or eliminating various liquid discharges from one or more emission control equipment devices (e.g., one or more wet flue gas desulfurization (WFGD) units). In another embodiment, the method and apparatus of the present invention is designed to reduce and/or eliminate the amount of liquid waste that is discharged from a WFGD unit by subjecting the WFGD liquid waste to one or more drying processes, one or more spray dryer (or spray dry) absorber processes, and/or one or more spray dryer (or spray dry) evaporation processes.
