Vapor-liquid contacting apparatus

摘要

A vapor-liquid contacting apparatus suitable for use as a fractionation tray is disclosed. The horizontal liquid support area of the apparatus has a flat vapor-liquid contacting area formed by closely spaced parallel members. The parallel members are shaped such that the elongated openings between adjacent members have a tapered shape which is smallest at the top. The apparatus may be used as a fractionation tray which has a low pressure drop and a low tendency for liquid to fall through the contacting area.
