Abstract

In a process for mixing reactant streams ( 1, 2; 5 ) to produce a product stream ( 10 ) using a mixing configuration ( 15, 16 ) having a number of reactant feed points, an excess component stream of one reactant is divided into two reactant substreams ( 1, 2 ) and fed into the suction region ( 3, 4 ) of a mixing space ( 12 ) at right angles to a deficient component ( 5 ) entering the mixing space ( 12 ).
