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.

Abstract: Processes for combining the stripping sections for two different reaction zones, such as a diesel hydrotreating zone and a naphtha hydrotreating zone. The stripping section includes an air cooler, a combined overhead receiver and two different separation sections. The two separation sections may be in the same column, but be fluidically separated. Alternatively the two sections may be in different columns. A stream from the second section may be used as a reflux from the first. While a stream from the combined overhead condenser may provide a reflux for the first section.

Abstract: An apparatus and process is disclosed for the cooling of a reactor effluent gas stream. The apparatus includes a two stage contact cooling system with a first stage wash zone and second stage wash zone. Each wash zone has a packed bed, or other type of mechanical system for contacting the gas stream with the cooling liquid. The liquid in the first stage will remove heavy components, allowing for a cleaner second stage that can be reduced in size.

Abstract: Methods and apparatuses for desulfurizing hydrocarbon streams are provided herein. In one embodiment, a method for desulfurizing a hydrocarbon stream includes separating the hydrocarbon stream into a heavier fraction and a lighter fraction. The heavier fraction includes a relatively higher amount of lower octane mono-unsaturates and the lighter fraction includes a relatively higher amount of higher octane mono-unsaturates. The method further includes hydrodesulfurizing the heavier fraction in a first hydrodesulfurization zone and hydrodesulfurizing the lighter fraction in a second hydrodesulfurization zone. Further, the method forms a hydrodesulfurized stream from the heavier fraction and the lighter fraction.
