Abstract
The device of the present invention delivers reactants to a reaction zone in a plug flow reactor. The feedblock encircles the reaction zone. Reactants enter the feedblock through an inlet port leading to a manifold for the delivery of reactants into a plurality of feed ports that are in connection with the reaction zone of a plug flow reactor. The invention additionally encompasses plug flow reactors including one or more feedblocks and the method of utilizing the feedblock for the reduction of radial variation in concentration upon entry of a reactant into the reaction zone.
Claims15
A method for minimizing radial variation in concentration upon entry of a reactant into a reaction zone of a plug flow reactor, the method comprising:
- positioning a feedblock having a plurality of circumferentially disposed feed ports in fluid communication with the reaction zone;
- and
- conveying the reactant through a manifold disposed within the feedblock such that reactant is fed into the reaction zone through the circumferentially disposed feed ports thereby minimizing radial variation of the reactant within the reaction zone.
A method for minimizing the polydispersity of polymerization reaction, the method comprising:
- delivering at least one fluid into a reaction zone of a plug flow reactor monomer through a plurality of circumferentially equidistant feed ports surrounding the reaction zone;
- and
- laterally mixing the monomer in the reaction zone for polymerization of the monomer while traveling in an essentially plug flow manner through the plug flow reactor.
