The CARBO-Tech Type PT low pressure-drop scrubber is especially suitable for absorption of gas and vapour such as SO2, HF, HCI, NH3, and CI2 and for odour removal and absorption where high transfer area and residence time is required. This scrubber can handle recycled streams containing minimal amounts of solids. It is not suitable for applications on heavy or sticky dust or where precipitation of salts may occur.

In operation, the dirty gas passes up through the packing while absorbing liquor flows downward. Extremely high contact surface areas are obtained which result in high mass and heat transfer rates. The cleaned gas passes out of the unit through the mist eliminator where complete removal of entrained liquor droplets takes place.

Packed tower tanks can be constructed using carbon steel, stainless steel, specialty alloys or plastics. Packing can be either ceramic or plastic material. Units are available with capacities ranging from 200 to 50,000 cfm.

Typical Applications

-Odor removal in organic chemical, meat packing, rendering, fish and general food processing plants
-Gaseous absorption in steel plants and in fertilizer and other chemical process industries
