An apparatus for distributing liquid over the cross section of a liquid-vapor contacting column comprising a distributor plate having orifices for downward liquid flow and risers for upward vapor flow. Above the distributor plate is a trough for receiving liquid to be distributed. The vapor risers directly below the trough extend through the trough. The trough floor has annular openings around the penetrating vapor risers to discharge liquid onto the distributor plate below.

Liquid distributor for a vapor-liquid contacting column

A sampling system for cryogenic liquid sampling which passes vaporized cryogenic fluid to an analyzer through a conduit having a defined restriction such as an orifice at or downstream of the input and which prevents choke flow in the conduit by simultaneously reducing the pressure which promotes choke flow and improving the ratio of the fluid pressure at and downstream of the restriction in the direction which resists choke flow.

Cryogenic liquid sampling system

Structured metal column packing with corrugations and textured surfaces having a defined construction of the corrugation corners which enables significantly improved performance especially under turndown conditions.
