Abstract: The present disclosure relates to a method and an apparatus for self-heat-extracting flash evaporation of a sulfuric acid alkylation reaction product. There is provided a method for self-heat-extracting flash evaporation of a sulfuric acid alkylation reaction product. One step is to coalesce and vaporize a preliminarily distributed sulfuric acid alkylation reaction product to cause preliminary vaporization of a hydrocarbon therein, thereby taking heat away and preliminarily separating the hydrocarbon from sulfuric acid. Another step is to subject the preliminarily separated alkylation reaction to reinforced separation, where the hydrocarbon is further vaporized to take heat away and further separate the hydrocarbon from the sulfuric acid. There is also provided an apparatus for self-heat-extracting flash evaporation of a sulfuric acid alkylation reaction product.

Abstract: A method and a device for synchronous high-speed photographing of microparticle rotation in a liquid cyclone field and for determining the rotation velocity of a microparticle in a liquid cyclone field by using a combination of a synchronous high-speed photographing system and a transparent microparticle containing two centrosymmetrically arranged inner cores having the same diameter. The method comprises: using a transparent microparticle comprising two inner cores having the same diameter and arranged centrosymmetrically as a rotation test particle; acquiring synchronously two groups of two dimensional image series of microparticle motion in a liquid cyclone field using two orthogonally arranged high-speed digital cameras; and reconstructing a three dimensional motion trajectory of the microparticle from the two groups of synchronous image series, and determining a rotation velocity of the microparticle in the cyclone field at the same time.

Abstract: 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.
