Plate Fin Fluid Processing Device
A device for processing fluids includes a number of fin layers with a number of plates separating the fin layers so that a fluid flow passage is defined through each fin layer. A first fluid inlet is in communication with a first end portion of the fluid flow passage, a first fluid outlet is in communication with a second end portion of the fluid flow passage, a second fluid inlet is in communication with the second end portion of the fluid flow passage and a second fluid outlet in communication with the first end portion of the fluid flow passage. The fluid flowing through the second inlet is subjected to a shearing action by the fin layers so that mass transfer to the fluid flowing through the first inlet occurs. The device may be used for both liquid-liquid processes, such as extraction, or gas-liquid processes, such as adsorption, absorption or desorption and reactions.
