Abstract
A process and apparatus cool and remove catalyst from a hot vaporous reactor effluent stream by feeding the hot vaporous reactor effluent stream comprising catalyst and a first quench liquid stream to a first quench chamber. The hot vaporous reactor effluent stream is directly contacted with the first quench liquid stream to cool the hot reactor effluent stream and wash catalyst therefrom into the first quench liquid stream. The first quench liquid stream and the vaporous reactor effluent stream are passed together through a bed while disengaging catalyst from the vaporous reactor effluent stream and transferring catalyst into the first quench liquid stream.
