Abstract
An intensified means of multicomponent fluid multistage vapor-liquid contact is disclosed. The contactor achieves the thermodynamic advantages of global countercurrency, the tray efficiency advantages of tray crosscurrency, and the point efficiency advantages of local cocurrency with liquid recirculation. Referring to FIG. 6, each tray has multiple compartments formed by compartment dividers 62, 63, and 64, and each compartment has a channel divider 69, 66, 67 which forms separate locally cocurrent riser channels and liquid downcomer channels.
