An integrated system for onboard scrubbing of a marine exhaust gas on a ship, comprising: a) a Venturi quencher having: i) two liquid inlets that feed quench water to the Venturi quencher; and ii) a hot exhaust gas entry that feeds the hot marine exhaust gas from an engine on the ship; and b) the rotating packed bed device, having: iii) a stationary gas distributor, placed along an outer circumference of the RPB device, that disengages a quenched marine exhaust gas from a cooled two-phase mixture, and uniformly distributes the quenched marine exhaust gas along the outer circumference of the RPB device; and iv) a stationary liquid distributor, centrally positioned, and with multiple liquid rings that are fitted with spray nozzles that spray a seawater along an inner circumference of the RPB device. Also, processes for using the integrated system, and a ship comprising the integrated system.

The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.

There is provided an active coke regeneration mixed vapor treatment method. The method comprises the following process steps of: A) performing a first water condensation on a mixed vapor produced during an active coke regeneration process by spray water in a first condensation zone; B) performing a second water condensation on the mixed vapor that is after the first water condensation by spray water in a second condensation zone, to further condensate and purify the mixed vapor; C) eliminating moisture in a gas through mist elimination from the gas fraction in the mixed vapor that is after the second water condensation, and discharging the remaining gas from the upper of the second condensation zone; and, D) discharging active coke micro powder in the mixed vapor that is after the second water condensation, with condensation water. In the present invention, an apparatus for implementing the abovementioned method is also provided.

A scrubber system for removing odorous and/or harmful gases from polluted gases/air comprising a scrubber body, a blower to supply the polluted gas into the scrubber body under pressure enabling the supplied polluted gas to travel from lower portion of the scrubber body to upper portion of the scrubber body and one or more diffraction units provided with supply of wash solution accommodated inside of the scrubber body and disposed in pathway of the polluted gas within the scrubber body to diffract the polluted gases/air with the wash solution thereby to clean the polluted gases/air and discharge clean gases/air through a scrubber body outlet at its top.

A scrubber system for removing odorous and/or harmful gases from polluted gases/air comprising a scrubber body, a blower to supply the polluted gas into the scrubber body under pressure enabling the supplied polluted gas to travel from lower portion of the scrubber body to upper portion of the scrubber body and one or more diffraction units provided with supply of wash solution accommodated inside of the scrubber body and disposed in pathway of the polluted gas within the scrubber body to diffract the polluted gases/air with the wash solution thereby to clean the polluted gases/air and discharge clean gases/air through a scrubber body outlet at its top. Each of diffraction units includes one or more modularly configurable diffraction plate having an assembly of spaced apart a perforated upper plate and a perforated lower plate wherein each said perforated upper plate and said perforated lower plate having plurality of passing holes on their planer surface and assembled one over the other enabling said passing holes in the perforated upper plate and the perforated lower plate are disposed in a zigzag pattern, whereby the polluted gases/air while moving upwards and upon contact with said wash solution in said diffraction unit while passing through said passing holes in said perforated upper and lower plates of said diffraction unit generate swirl bubbles within the wash solution under pressure of said polluted air/gases moving upwards for maximizing contact with said polluted gases/air and efficient cleaning of the polluted gases/air for release of clean gases/air through the scrubber body outlet.

The present disclosure relates to an apparatus and method of removing pollutants from exhaust gas by wet scrubbing process. In a scrubber apparatus of the present disclosure, an exhaust gas is first scrubbed in a primary mixing zone, the partially scrubbed gas discharged from the primary mixing zone is subsequently mixed forcibly in a secondary mixing zone before being discharged for polishing, demisting and/or reheating.

A filtering module includes a cyclone having a contaminated air inlet part into which external contaminated air and cleaning water cleaning the contaminated air are each introduced, and a cleaned air outlet part through which air cleaned by bringing the cleaning water into contact with the contaminated air is discharged; a water tank coupled to the cyclone, to which the cleaning water cleaning the contaminated air is introduced, and storing mixed water in which a pre-stored fluid and the cleaning water are mixed; and a fluid circulating part providing the mixed water stored in the water tank to the contaminated air inlet part.
