Abstract
Reaction equipment for chemical processes, e.g., saponification processes having reaction times of about 2-8 minutes. The reactants are measured, and fed sequentially into a reactor. The reactants are sequentially mixed and reacted by recycling, and at the end of the reaction the recycling is terminated and the finished product is pumped to storage. A microprocessor controller may be provided to sequence the feed and amount of reactants and the reaction times.

Apparatus for carrying out mixing or chemical reactions in the liquid state comprising:
- (a) a reactor or mixing vessel having sidewalls and a cone-shaped bottom section;
- (b) a conduit extending vertically through said vessel, wherein said conduit is provided with a first set of openings and a second set of openings therein, said first set of openings being positioned near said bottom section of said vessel, and said second set of openings being positioned above said first set of openings, said first set of openings and said second set of openings having means positioned therebetween to direct a flow of liquid exiting said conduit toward said sidewalls of said vessel;
- (c) a recirculating system connected to said vessel, said recirculating system having outlet means and inlet means adapted to mix and recirculate the liquid contents of said vessel out of said vessel through a recirculating valve and back into said vessel;
- (d) supply means for introducing liquid materials into said vessel;
- and
- (e) means for diverting the liquid contents of said recirculating system out of said recirculating system.
A process for carrying out mixing or chemical reactions in the liquid state comprising the steps of
- A. sequentially introducing chemical components into a conduit that extends vertically through a reactor or mixing vessel having sidewalls and a cone-shaped bottom section, said conduit being provided with a first set of openings and a second set of openings therein, said first set of openings being positioned near said bottom section of said vessel, and said second set of openings being positioned above said first set of openings, said first set of openings and said second set of openings having means positioned therebetween to direct a flow of liquid exiting said conduit toward said sidewalls of said vessel;
- B. continuously recirculating the contents of said vessel through a recirculating system connected to said vessel, said recirculating system having outlet means and inlet means adapted to mix and recirculate the liquid contents of said vessel out of said vessel through a recirculating valve and back into said vessel;
- and
- C. following the completion of all chemical reactions in the process, diverting the liquid contents of said recirculating system out of said recirculating system.
