This may be achieved by a vaned rotor rotatable about a horizontal axis or other means. The carbon dioxide atmosphere is preferably maintained at a pressure of about 100 psig (6.8 bars). The degree of carbonation may be varied by varying the time for which the carbonation operation is carried on.

Abstract: A phoretic enhanced-gravity particulate removal system (10) is provided for removing particulates and gaseous pollutants from a particulate laden gas. The particulate laden gas is initially brought into a housing (12) between a plurality of upper and lower planar members (20 and 22). The facing surfaces of the planar members (20 and 22) provide for a temperature gradient. The particulate laden gas is driven through a saturation zone in a gas flow channel (26) formed by the planar members (20 and 22). The particulates begin to nucleate and grow at a rapid rate due to supersaturation provided by the temperature gradient and the wetting of the facing surfaces of the planar members (20 and 22). The growth is rapid and causes the nucleating particulates to be driven in a path (58) towards a capturing mechanism (38) through phoretic and gravity forces. Increased nucleation rate and growth of the nucleating particles allow for a maximization of the amount of particulates captured and removed from the housing (12).
