Quench assembly design

Abstract From the Canadian patent

According to this invention, a quench, assembly having improved mixing efficiency comprises a series of mixing zones: quench fluid inlet zane: quench box mixing zone; a jet stirred mixing zone: and a distributor zone. In the quench fluid inlet zone quench fluid is introduced to fluid from the catalytic bed above. The quench fluid is introduced through holes in a quench pipe, creating a jets of quench fluid which entrain and mix the reactant fluid typically partially reacted, from the bed above. This mixing zone is separated from the quench mixing zone by means of a horizontally disposed plate having a central opening therein. The reaction fluid and quench fluid enter the quench mixing zone …
