(under the class definition) Process in which solid or liquid particles are removed from a gas by causing the gas and solid or liquid particles entrained therein (a) to contact a solid surface to effect an abrupt change in direction of the gas which (i) causes the solid or liquid particles to drop out and remain behind while the gas flows on or (ii) causes the solid or liquid particles to move to the outer periphery of a rotating gas stream in a concentrated layer to permit such layer to be separated from the gas with fewer or no entrained particles or (b) to contact a gas stream to effect an abrupt change in direction of the gas which causes the solid or liquid particles to drop out and remain behind while the gas
flows on.
