DEFINITION

Classification: 208/433

Simultaneous treatment with gaseous additive and liquid solvent:

(under subclass 428) Subject matter wherein a normally liquid solvent and a normally gaseous additive come into direct contact with the feed or intermediate material in a single zone.

(1) Note. "Normal" conditions are usually based upon normal operating conditions of the process involved. When such process conditions are not stipulated (i.e., temperature, pressure) normal conditions are taken to be at standard conditions (i.e., 25 deg. C, 1 atom pressure).

(2) Note. The gas may be hydrogen-containing gas.

SEE OR SEARCH THIS CLASS, SUBCLASS:

418, for a process wherein a feed-stock is contacted with hydrogen and a solvent produced in the process and recycled from a late stage, in the same zone or different zones.
