A predominantly liquid filled, vapor-liquid chemical reactor having an improved distributor plate assembly is disclosed. At least one of the plates in the assembly is formed with an active area having a plurality of apertures formed through the plate, an opening, and a downwardly depending lip proximate the opening. As vapor ascends through the reactor, the plate and the lip cooperate to trap the vapor upwardly against the bottom of the plate, forming a vapor region. This vapor region facilitates vapor liquid interaction and the flow pattern of liquid through the reactor.

Predominantly liquid filled vapor-liquid chemical reactor

Wet refinery sludges are disposed of by feeding them into a delayed coking process. The sludge is fed to the blowdown drum of the delayed coking process and mixed with oil condensed from the coke drum overhead, and the resulting sludge-oil mixture is fed to the coke drum where it is converted into coke. In order to remove the water from the sludge, a portion of the sludge-oil mixture is heated and recirculated to the blowdown drum where it provides the heat for drying and heating the sludge. The recirculating sludge-oil mixture is heated by a low level heat source, such as one of the fluid streams taken off from the fractionator.
