Abstract: A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of offset contacting modules in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Half modules comprise downcomers against the shell of the vessel for transporting liquid to the subjacent stage.

Abstract: The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading and reactor pressure drop. More particularly, a scale collection device is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.

Abstract: A combined heat exchanger and reactor for use with an ionic liquid catalyst reaction. The reactor includes an outer shell configured to receive a cooling fluid which may remove heat from reactions occurring within hollow members disposed inside of the outer shell. The hollow members preferably include one or more static mixers for mixing fluids and dispersing ionic liquid into droplets. A separation zone may be disposed beneath the hollow members which will separate the effluent and provide a hydrocarbon stream and an ionic liquid stream. Multiple combined heat exchanger and reactor may be arranged in series.

Abstract: An ionic liquid reactor and a process for controlling heat generation from an ionic liquid reactor unit. The ionic liquid reactor includes an internal heat exchanger. Impellers break the ionic liquid into small droplets to ensure reactions and mix the fluids to ensure reactions and enhance heat exchanger. Baffles may be used to direct the flow of the fluids within the reactor.

Abstract: A method for recovering entrained ionic liquid from an immiscible phase containing droplets of ionic liquid is described. The method includes contacting the immiscible phase containing the droplets of ionic liquid with a scrubbing ionic liquid phase in a scrubbing zone. The immiscible phase containing the droplets of ionic liquid has a first level of droplets of ionic liquid. At least a portion of the droplets of ionic liquid are transferred to the scrubbing ionic liquid phase to form a recovered ionic liquid phase comprising the scrubbing ionic liquid and the transferred portion of the droplets of ionic liquid and a second immiscible phase having a second level of droplets of ionic liquid lower than the first level. The second immiscible phase is separated from the recovered ionic liquid phase.
