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.
Claims18
An ionic liquid catalyst reactor unit comprising:
- a first reaction zone having an inlet for ionic liquid, an inlet for a hydrocarbon stream, and an outlet for an effluent stream;
- a separation zone configured to receive the effluent stream and separate the effluent stream into a hydrocarbon phase and an ionic liquid phase;
- and,
- a first heat exchange zone configured to receive at least a portion of the effluent stream from the first reaction zone and comprising:
- an outlet for a cooled effluent stream, and an outlet for ionic liquid wherein the first heat exchange zone comprises a heat exchanger with a shell and wherein the separation zone is disposed within the shell.
A process for controlling the temperature of a reaction performed in the presence of an ionic liquid catalyst, the process comprising:
- performing a reaction in the presence of an ionic liquid catalyst to form an effluent, wherein the reaction is performed in a reaction zone;
- removing heat from at least a portion of the effluent from the reaction zone in a heat exchange zone with a cooling fluid to provide a cooled effluent;
- separating the effluent in a separation zone into a hydrocarbon phase and an ionic liquid phase and;
- separating ionic liquid from the effluent from the reaction zone within the heat exchange zone.
