Abstract:
1. A process for minimizing the emission of particulate matter and precursors thereof from a flue gas stream of an engine, the flue gas stream comprising particulate matter and precursors thereof and at least one gaseous component, which process comprises the steps of: a. obtaining a flue gas stream of an engine comprising particulate matter and precursors thereof; b. increasing the moisture content of said stream by contacting the same with a first aqueous medium in an amount and at a temperature at which at least 50% of the water content of the first aqueous medium is evaporated; whereby a moisture laden gas stream, optionally containing suspension droplets, is formed; c. cooling said moisture laden gas stream, said cooling comprising contacting said moisture laden gas stream with a second aqueous medium, whereby suspension droplets are formed; and d. applying a centrifugal force to said moisture laden gas stream and to said suspension droplets to effect the swirling thereof; whereby a treated gaseous stream and an aqueous stream are formed;
