Abstract

A method and apparatus for removing TDI from a gas in which the gas containing the TDI is forced through a scrubber tank. A first water spray is in fluid communication with the gas flowing through an inlet pipe and initially reacts the TDI in the gas with water. The gas is directed against a water surface at the bottom of the tank and thereafter, flows up an interior side wall of the tank. Deflectors mounted on the side wall disrupt the laminar flow of the gas and redirect it in a turbulent manner through a second water spray prior to the gas exiting the scrubber tank.
