Abstract

Abstract A gas-gas phase contactor/process, especially adopted for high temperature reactions, e.g., for the production of hydrochloric acid, comprises means for separately establishing at least two disparate gaseous feedstreams, means for disintegrating each such feedstream into a registered plurality of substreams thereof, one of each such substream being complementary to at least one eother, and means for establishing homogeneous unit volumes of gaseous reaction mixture which comprise said complementary fractions of each such disintegrated feedstream.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 192 words
A process for intimately contacting and reacting at least two disparate gaseous phases, comprising the steps of: A. separately establishing at least two disparate gaseous feedstreams of said at least two gaseous phases, respectively, B. separating each of said feedstreams into a plurality of substreams such that all of one of said gaseous phases is divided into a plurality of first substreams and all of another of said gaseous phases is divided into a plurality of second substreams, the number of said first substreams equaling the number of said second substreams, C. directing each of said first substreams toward a respective one of said second substreams within a chamber to combine each of said first substreams with a respective one of the second substreams at a respective separate mixing zone before said second substreams are combined with one another and before said first substreams are combined with one another, in order to establish a plurality of homogeneous blended mixtures of said first and second gaseous phases, D. thereafter combining together said blended mixtures to form a final mixture, and E. thereafter reacting said first and second gaseous phases of said final mixture.
Claim 2
Dependent Claim 192 words
A process for intimately contacting and reacting at least two disparate gaseous phases, comprising the steps of: A. separately establishing at least two disparate gaseous feedstreams of said at least two gaseous phases, respectively, B. separating each of said feedstreams into a plurality of substreams such that all of one of said gaseous phases is divided into a plurality of first substreams and all of another of said gaseous phases is divided into a plurality of second substreams, the number of said first substreams equaling the number of said second substreams, C. directing each of said first substreams toward a respective one of said second substreams within a chamber to combine each of said first substreams with a respective one of the second substreams at a respective separate mixing zone before said second substreams are combined with one another and before said first substreams are combined with one another, in order to establish a plurality of homogeneous blended mixtures of said first and second gaseous phases, D. thereafter combining together said blended mixtures to form a final mixture, and E. thereafter reacting said first and second gaseous phases of said final mixture.
Claim 3
Dependent Claim 37 words
