An improved vapor-liquid contact grid apparatus which maximizes the generation of small drops and which is inexpensive to manufacture and easy to construct is disclosed. The grid apparatus consists of multiple layered grids, each grid being formed of upright grid members and connectors. The grid members carry vanes, formed from the member itself by a process of slitting and bending, which vanes extend out into the region between the upright grid members, thus restricting vapor passage, providing drip points and increasing the effective surface area for gas-liquid exchange. The grid members and connectors are arranged in an 'egg carton'-like fashion to provide a simple, yet sturdy, grid.

Vapor-liquid contact grid

A reverse-jet scrubber apparatus and method for removing gaseous contaminants, such as sulfur dioxide, and particulate matter from a combustion gas stream, employing low energy and reduced amounts of scrubbing liquid, which apparatus comprises: an elongated conduit; and a plurality of jet-spray nozzles centrally disposed and spaced apart from each other in the conduit and adapted to spray under high pressure a caustic scrubbing liquid countercurrently into a high-velocity, combustion gas stream, to form separate spray scrubbing zones covering the cross-sectional area of the conduit, whereby a combustion gas stream is scrubbed and a clear gas stream is recovered downstream of the scrubbing zones.
