US Patent:

53605349, Nov 1, 1994

Filed:

May 24, 1993

Appl. No.:

8/065209

Inventors:

Lynn H. Rice - Palatine IL
James G. Hagen - Rolling Meadows IL
Brian H. Johnson - Long Grove IL

Assignee:

UOP - Des Plaines IL

International Classification:

C10G 35085
C07C 522

US Classification:

208139

Abstract:

The benzene content in a gasoline pool is reduced by an isomerization process that splits a benzene-containing C. sub. 4 -C. sub. 6 feedstream between at least two reaction zones and combines the feed fractions with effluent streams. The splitting of the feed stream distributes the heat of reaction over two reactors and lowers the relative exotherm. The lower exotherm for benzene saturation permits higher benzene feeds to be processed without reducing product quality.

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.

C07C 2/62

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.
