Scrubber - Wikipedia

Wet scrubbers can also be used for heat recovery from hot gases by flue-gas condensation. In this mode, termed a condensing scrubber, water from the scrubber drain is circulated through a cooler to the nozzles at the top of the scrubber. The hot gas enters the scrubber at the bottom.

Wet Scrubber Application Guide - TEC Engineering

Gas streams entering a wet scrubber may or may not be fully saturated, however they will exit the scrubber fully saturated. This process of saturation results in a change in volume, temperature and density. The overall scrubber size (diameter) is a function of velocity of saturated gas through the scrubber shell.

40 CFR § 63.11237 - What definitions apply to this subpart

Waste heat boilers are heat exchangers generating steam from incoming hot exhaust gas from an industrial (e.g., thermal oxidizer, kiln, furnace) or power (e.g., combustion turbine, engine) equipment. Duct burners are sometimes used to increase the temperature of the incoming hot exhaust gas.

CHAPTER 41 WET GAS SCRUBBING

CHAPTER 41. WET GAS SCRUBBING. Wet scrubbers use a liquid to remove solid, liquid, or gaseous contaminants from a gas stream. The scrubbing liquid performs this separation by dissolving, trap- ping, or chemically reacting with the contaminant. Scrubbers are used extensively to control air polluting emissions.

Wet flue gas cleaning and heat recovery

It has often been proven numerous times that CHP plants can achieve even up to 20% of their heat production with flue gas heat recovery. Wet flue gas cleaning, in turn, is an efficient way to bring the flue gases down to near zero emission levels in SO 2, HCl and NH 3.

Gas cleaning in flue gas from combustion of biomass

temperature heat recovery is a good wet solution. In other cases, wet systems are seldom a good solution for particulate removal only. Water soluble gases are removed effectively in wet and dry absorption but dry scrubbers require an excess of chemicals for a high removal efficiency. Wet scrubbers normally require special treatment of the waste water.

The outlet from the incinerator waste heat boiler enters the caustic scrubber to absorb the SO2 from the gas. The gas leaving the caustic scrubber will contains less than 5 ppmv of SO2 which is routed through a short stack to a safe location. It may be required to heat the stack gas prior to emitting to the atmosphere to prevent condensation.
