A gas-liquid mass transfer apparatus and method, such as for the rapid heating of a liquid stream by a heated gas stream, such as steam, or the rapid dissolving of a gas stream into a liquid stream, which apparatus comprises: a housing having an axial flow path; static or motionless mixing elements disposed in the axial flow path; and passages in the housing to provide for the direct introduction of the gas stream into and about the liquid stream in the axial flow path and substantially along the length of the static mixing elements to provide a mixed product stream.

A direct contact gas-liquid mass transfer apparatus, which apparatus comprises: (a) a housing; (b) a conduit within said housing which conduit defines an axial flow path for a liquid stream, the conduit having an inlet, an outlet and a plurality of peripherally spaced openings positioned generally perpendicular to and along the length of the axial flow path; (c) motionless mixing means composed of one or more mixing elements in the said axial flow path; (d) means to introduce a liquid stream into the inlet; (e) means to introduce the gas stream through the plurality of openings and into and generally peripherally about the motionless mixing means and along substantially the length of the motionless mixing means and radially into the axial flow path containing the liquid stream for a rapid mixing of the gas and liquid streams to provide a mixed liquid product stream, the gas stream introduced at a gas-liquid volume ratio of about 2 to 1 or greater; and (f) means to withdraw a mixed liquid product stream from the outlet. A direct contact method for the rapid mixing of a liquid and gas stream in a conduit having a motionless mixer, which method comprises: (a) flowing a liquid stream along a defined axial flow path in a conduit; (b) introducing a gas stream into the liquid stream at a gas-liquid volume ratio of greater than 2 to 1 generally perpendicularly and peripherally about the axial flow path of the liquid and the motionless mixer in the conduit; and (c) continuously subdividing the gas and liquid steam in the conduit and along the axial flow path by said motionless mixer to provide for the rapid mixing of said gas and liquid streams in the axial flow path; and (d) withdrawing from the axial flow path a mixed product stream.
