Abstract

The invention discloses a production device for preparation of isooctane by isobutane and butene alkylation reaction. The device includes a raw material dehydrator D201, a heat exchanger, a light hydrocarbon removing tower C101, a butene feed heater E101, and a butene raw material buffer tank D101 that are communicated with an alkylation reactor feed end in order, and also includes a flash tank D203, a pickling tank D209, an alkali washing tank D210, a washing tank D211, a deisobutanizer and a deisobutanizer C201 that are communicated with an alkylation reactor discharge end in order. Specifically, the upper part of the deisobutanizer C201 is communicated with a deisobutanizer return tank D212, an isobutane raw material conveying pipe is communicated with the return tank D212, a deisobutanizer reflux pump P209A/B sends the isobutane raw material and circulating isobutene back to the alkylation reactor through a pipeline and is communicated with a butene raw material convey pipe through a tee joint.

Description

Technical field [0001] The invention relates to the field of petrochemical industry, in particular to a production device for preparing isooctane by reacting isobutane and butene. Background technique [0002] The alkylation reaction of isobutane and butene to prepare isooctane is a common method for preparing isooctane. The generally used process is that the isobutane-butene feed enters the reactor together with the device circulating isobutane and refrigerant. Under the catalysis of sulfuric acid, the isobutane and butene undergo an alkylation reaction to form alkyl groups. Petrol. [0003] The alkylation reaction of isobutane and butene is more complicated. The main reaction conforms to the cationic chain reaction mechanism. The addition of isobutane and butene to isooctane. The side reactions mainly include self-polymerization, cleavage, isomerization, and ester. Chemical reactions. The main reaction is as follows: [0004] 1. C 4 H 8 + H 2 SO 4 → (C 4 H 9 ) HSO 4 [0005] 2...
