The present invention provides a fouling prevention method and a method for olefin oligomerization, wherein in the method for olefin oligomerization, a predetermined anti-fouling agent is added, thereby minimizing the production of sticking byproducts generated during the reaction and fundamentally preventing the fouling of the byproducts, generated during the reaction, on an inner wall of a reactor.

The disclosure provides a short-process separation system for separating ionic liquid from alkylation reaction effluent, comprising an alkylation reactor, an ionic liquid storage tank, a primary coalescence separator, a secondary coalescence separator, a flash tank, a low-temperature fine coalescence separator and a fractionating tower that are linked in order. The inlet of the ionic liquid storage tank communicates with the bottom flow ports of the primary coalescence separator, the secondary coalescence separator and the low-temperature fine coalescence separator through delivery lines, and the outlet of the ionic liquid storage tank communicates with the return port of the alkylation reactor through a delivery pump. The alkylated oil collected from this system has a high degree of cleanliness, and can be used directly as a component for formulating clean gasoline. The ionic liquid catalyst collected therefrom may be directly returned to the alkylation reactor for cycle use.

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.
