Patent ID: 7074371

Claim:
A mixing system for distributing vapor and liquid across a reactor, comprising: a reactor vessel defined by a reactor wall; a collection tray for receiving vapor and liquid; at least one quench injector for introducing quench fluid into said mixing system at least one injection location above said collection tray; and at least one conduit extending through said collection tray into a mixing chamber for permitting the flow of fluid from above said collection tray and into said mixing chamber; wherein quench fluid is introduced into said mixing system by said at least one quench injector at the at least one injection location wherein the kinetic energy of the quench fluid at said at least one injection location is greater than the kinetic energy of the transverse process fluid flow at said at least one injection location, wherein said at least one injection location is selected such that the kinetic energy square root ratio of the quench flow and transverse process fluid flow, (KE Q /KE X ) 1/2 , is in the range of 3 to 150.
