An oxygen gas jet generated from said oxygen nozzle and a fuel gas jet generated from said fuel gas nozzle have the same elevation in the regenerator. In a regenerator, an oxygen gas distributor and a fuel gas distributor may be located in a mixing chamber. A fuel outlet of a fuel nozzle of the fuel gas distributor may be within a fifth of the height of the mixing chamber from an oxygen outlet of an oxygen nozzle of the oxygen gas distributor.

Abstract: An apparatus for separating solid particles from a stream of a mixture of gaseous fluids and solid particles has a separation vessel. A mixture conduit extends vertically into a central section of the separation vessel and defines a discharge opening located within the vessel and tangentially oriented for discharging the stream into an open interior of the vessel and imparting a tangential velocity to the stream. A gas recovery conduit within the separation vessel has an inlet for withdrawing gaseous fluids from within the open interior of the separation vessel at a location below the discharge opening and radially offset from the mixture conduit. An intermediate portion of the gas recovery conduit is located above the inlet within the separation vessel and has a diameter greater than a diameter of the inlet.

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.
