Abstract
A process for distributing quench fluid to a stream of product comprising contacting a feed stream with a stream of catalyst to convert the feed stream to product. The quench fluid is sprayed into the stream of product from a first distributor through at least one first opening centered at a first radial position and from a second distributor through at least one second opening centered at a second radial position different from the first radial position. Catalyst is preferably separated from the product stream prior to quenching. The process may include a first set of first distributors and a second set of second distributors.

A process for distributing a quench fluid to a stream of product comprising:
- contacting a feed stream with a stream of catalyst in a reaction chamber of a reactor to convert the feed stream to the stream of product, wherein the stream of product moves upwardly in the reactor;
- and
- quenching the stream of product in a quenching chamber of the reactor by spraying the quench fluid into the stream of product from a plurality of first distributors and a plurality of second distributors,
- wherein each of the first and second distributors has at least one opening and a center of the at least one opening,
- wherein the centers of the first distributors are located at first radial positions that define a first imaginary circle, and the centers of the second distributors are located at second radial positions that define a second imaginary circle, and
- wherein the second imaginary circle is different from the first imaginary circle.
A process for distributing a quench fluid to a stream of product comprising:
- contacting a feed stream with a stream of catalyst in a reaction chamber of a reactor to convert the feed stream to the stream product, wherein the stream of product moves upwardly in the reactor;
- mixing a gas with the quench liquid in a plurality of first distributors and a plurality of second distributors to atomize the quench liquid;
- and
- quenching the stream of product in a quenching chamber of the reactor by spraying the quench fluid into the stream of product from the plurality of first distributors the plurality of second distributors,
- wherein each of the first and second distributors has at least one opening and a center of the at least one opening,
- wherein the centers of the first distributors are located at first radial positions that define a first imaginary circle, and the centers of the second distributors are located at second radial positions that define a second imaginary circle, and
- wherein the second imaginary circle is different from the first imaginary circle.
