Abstract: In the recovery of solids such as titanium oxide from the hot gas in which it is produced by reaction of titanium tetrachloride and oxygen, the gas is first cooled to below about 800* C. by mixing with additional gas, it is further cooled by direct heat exchange with liquid flowing down the walls of a converging zone having a taper angle greater than about 7*, the gas flow rate ranging from about 10 to 100 meters per second, and then making the gas pass through a spray of liquid. The resulting product has the gas removed and partially recycled for initial cooling and a part of the liquid suspension of oxide is recycled as the cooling liquid.
