Abstract: A reboiler in fluid communication with a fractionator column in an offshore low temperature process removing carbon dioxide from natural gas has a vessel volume. A carbon steel tubing bundle is disposed within the vessel volume. Each tube in the bundle has an outer surface with a porous granular metal layer deposited thereon. The granular metal layer comprises a pore size distribution which promotes bubble nucleation during vaporization of a nearly pure liquid carbon dioxide stream.

Abstract: The present invention relates to an apparatus for gas-liquid distribution. More specifically, the present invention relates to a gas-liquid distribution device that may be used in an ionic liquid co-current gas and liquid up-flow reactor designed to distribute gas uniformly across the reactor cross section through restriction orifices on distributors located across the distribution tray.

Abstract: Processes for controlling the rate and temperature of cooling fluid through a heat exchange zone in, for example, an alkylation reactor using an ionic liquid catalyst. A cooling fluid system may be used to provide the cooling fluid which includes a chiller and a reservoir. The cooling fluid may pass from the reservoir through the heat exchange zone. A bypass line may be used to pass a portion of the cooling fluid around the heat exchange zone. The amount of cooling fluid may be adjusted, with a valve, based upon the temperature of the cooled process fluid flowing out of the heat exchange zone. Some of the cooling fluid from the chiller may be circulated back to the chiller in a chiller loop.

Abstract: An ionic liquid reactor unit and a process for controlling heat generation from an ionic liquid reactor unit. The ionic liquid reactor unit may include an external heat exchanger. The effluent from the reactor is separated in a separation zone allowing the hydrocarbon phase to transfer heat to a cooling fluid. The heat exchanger may be a tube-in-shell, a spiral plate heat exchanger, a hair pin heat exchanger. The heat exchanger accommodates the separation of the ionic liquid from the hydrocarbon phase, and may allow for the ion liquid to be drained.

Abstract: A method of controlling a hydrocarbon conversion process is described. The method involves introducing a reactant into a reaction zone containing an ionic liquid catalyst. The reaction zone has at least two zones. The mass transfer resistance in the second zone is greater than the mass transfer resistance in the first zone.
