WebThe VOC load to the scrubbers in this division primarily consists of acetic acid (and other carboxylic acids). The scrubber is 4 feet in diameter and has about 8 feet of 2-inch packing. Fresh water is sprayed at the top of the packing at 4 to 6 gpm; water from the underflow is recirculated to the middle of the scrubber. WebDry scrubbers are used primarily to remove acids found within gasses. The dry sorbent used to remove the acid from the gas is usually made of an alkaline slurry. This slurry is basic in nature and will neutralize the acid found in the gas. This sorbent can be mixed with the acid gas in two ways. WebDry Sorbent Injection (DSI) refers to the practice of injecting a dry alkaline mineral into a flue gas stream to reduce acid gas emissions (i.e. SO 3 /H 2 SO 4, HCl, SO 2, and HF).
