Problems solved by technology

[0002] At present, the refining of crude oil will produce petroleum gas as a subsidiary product. After refining and a series of reactions, petroleum gas can be used to obtain isooctane, the main blending substance used to blend base gasoline. Gasoline added with isooctane has both combustion and antiknock properties. A large amount of concentrated sulfuric acid is needed as a catalyst in the production process of isooctane, and these catalysts will generate a large amount of acid gas to be discharged. Therefore, it is necessary to design an energy-saving and efficient non-polluting isooctane Recycling production line

Abstract

Disclosed is a pollution-free isooctane regeneration production line. The pollution-free isooctane regeneration production line is characterized by comprising a coolant pump (2), a raw material buffer tank (3), a depropanizer (4), a depropanizer reflux drum (5), a dehydrater (6), a reactor (7), a sulfuric acid settler (8), an acid pickling settling chamber (9), an alkali cleaning settling chamber (10), a deisobutanizer (11), an n-butane removal tower (12) and a sulfuric acid regeneration production line. The pollution-free isooctane regeneration production line has the advantages that the isooctane regeneration production line with a tail gas regeneration device is rational in process layout, efficient and environment friendly, and raw materials can be developed and utilized to the uttermost degree by recycling of tail gas.

Description

technical field [0001] The invention relates to the technical field of petroleum gas deep processing, in particular to a pollution-free isooctane regeneration production line. Background technique [0002] At present, the refining of crude oil will produce petroleum gas as a subsidiary product. After refining and a series of reactions, petroleum gas can be used to obtain isooctane, the main blending substance used to blend base gasoline. Gasoline added with isooctane has both combustion and antiknock properties. A large amount of concentrated sulfuric acid is needed as a catalyst in the production process of isooctane, and these catalysts will generate a large amount of acid gas to be discharged. Therefore, it is necessary to design an energy-saving and efficient non-polluting isooctane Recycling production line. Contents of the invention [0003] The present invention is mainly aimed at the present, the refinement of crude oil will generate auxiliary product petroleum ga...
