Abstract

The invention discloses an isooctane production line. The isooctane production line comprises a coolant pump (10), a raw material buffer tank (11), a depropanization tower (12), a return tank (13), a dehydrater (20), a reactor (21), a flash tank (22), a pickling settling chamber (23), an alkali wash settling chamber (24), a deisobutanizer (25) and an n-butane removal tower (26), wherein the raw material buffer tank (11) comprises a tank shell (15) and a group of separators (16). The isooctane production line disclosed by the invention has the advantages that due to the group of separators in the buffer tank, the gas flow time in the buffer tank is increased, and the liquefaction efficiency is improved; the tank body is separated into an upper part and a lower part by a spherical separator, so that the contact area between mixed gases and condensing agents is enlarged by the spherical separator, and the cooling effect is improved; the flash effect is improved by changing the contact area and time between liquid in the flash tank and air; and the whole production line is reasonable in structure and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of petroleum gas deep processing, in particular to an isooctane production line. Background technique [0002] At present, through refining and a series of reactions, petroleum gas can obtain isooctane, which is the main blending substance used to blend base gasoline. The combustion and antiknock properties of gasoline with isooctane can be greatly improved. During the reaction in the propane tower, the mixed gas generated by the reaction needs to be cooled into a liquid state through the reflux tank and recycled to the depropanizer for secondary separation. The cooling efficiency of the existing reflux tank is not high, and the discharge of the reflux tank cannot be well controlled. It is easy to discharge the mixed gas in the tank directly to the depropanizer, resulting in waste of energy. The existing raw material buffer tank and flash tank have low working efficiency, which makes the working efficiency o...
