Abstract:
An apparatus for directly contacting a first fluid with a second fluid, said apparatus comprising;a sealed chamber assembly comprising a chamber wall defining a chamber bore having a chamber bore diameter and a chamber longitudinal axis, said chamber wall comprising an injection port extending through said chamber wall perpendicular to the longitudinal axis of the chamber bore and tangential to an inner periphery of said chamber assembly, said injection port being in fluid communication with said second fluid; a combining tube comprising a combining tube wall defining a combining tube bore having a combining tube bore diameter that is less than said chamber bore diameter and having a combining tube longitudinal axis which is substantially the same as said chamber longitudinal axis, said combining tube bore comprising an upstream port and a downstream port in fluid communication with said first fluid, said chamber wall and said combining tube wall defining an annular space therebetween, said chamber wall being at radial distance from said combining tube wall which is greater than 40% of said injection port diameter; said combining tube wall comprising an upstream set of perforations adjacent to said upstream port, a downstream set of perforations adjacent to said downstream port, and an unperforated section between said upstream set of perforations and said downstream set of perforations, said unperforated section being adjacent to said injection port and extending beyond said injection port in both the upstream and downstream directions along said combining tube wall, wherein said upstream set of perforations and said downstream set of perforations have perforation longitudinal axes at an upstream to downstream angle to said chamber longitudinal axis of from about âˆ’60 to about 60Â° and have a lateral offset to said chamber longitudinal axis of from about âˆ’15Â° to about 15Â°.
