ABSTRACT:
Vapor and liquid contact structure for distillation, fractionation, rectification, absorption, and the refining, in a column, of various liquid materials such as petroleum, chemical, and alcohol solutions. Provision is made for the inclusion of vertically-spaced bubble plate chambers, having respective liquid/vapor contact devices, to accommodate contact of counter-current flows of reflux liquid and vapors. Downcomer means including slanted ramps, disposed outside of the vapor conduit-defining interior, define elongate downcomer structure for liquid flow and thereby, i.e., by such slanted construction, reduce froth or foam passing to a next lower contact device, eliminating unwanted counter-current gas entrainment between contact devices. Liquid flow rates over exit weirs beyond 30 gpm/inch are obtained. Downcomer reflux reservoir depth can be adjusted by an adjustable gate proximate the slot opening to a given contact device. Descending reflux liquid flow is kept outside of primary vapor flow, secondary vapor evolving from descending reflux being conducted circuitously back into the primary vapor flow for ascent to the next-above contact device. Plate efficiency is enhanced through maximum plate-area effective use and unidirectional liquid-flow over such plates; inter-plate vapor flow is unobstructed. Column sections are constructed in essentially identical modules which can be stacked and secured together to reduce fabrication and engineering costs.
