Superposition oil hydrogenation device and method capable of producing isooctane

Abstract

The invention discloses a superposition oil hydrogenation device and method capable of producing isooctane, and belongs to the technical field of petrochemical engineering. The device comprises a catalytic distillation hydrogenation column, a condenser, a reflux tank, a reboiler, a first compressor and a hydrogenation reactor; the top of the catalytic distillation hydrogenation column is connectedwith the condenser, the condenser is connected with one inlet of the reflux tank, one outlet of the reflux tank is connected with the first compressor, and the other outlet of the reflux tank is connected with the catalytic distillation hydrogenation column; the reboiler is arranged at the bottom of the catalytic distillation column; and the bottom of the hydrogenation reactor is connected with the catalytic distillation hydrogenation column. According to the superposition oil hydrogenation device and method capable of producing the isooctane, olefin in superimposed oil can be saturated, requirements of the superposition oil as a vehicle gasoline blending component are met and the isooctane is produced as needed, a hydrogenation reaction is separately carried out on different components in the superimposed oil through the catalytic distillation column and the hydrogenation reactor, the equipment and operation costs can be reduced, and the purpose of energy saving and flexible operation is achieved.

Description

technical field

[0001] The present application relates to the technical field of petrochemical industry, in particular to a superimposed oil hydrogenation device and method capable of producing isooctane. Background technique

[0002] On September 7, 2017, the State Administration of Quality Supervision and the Standardization Management Committee issued and simultaneously implemented two standards, GB18351 "Ethanol Gasoline for Vehicles (E10)" and GB 22030 "Ethanol Gasoline Blending Components for Vehicles". It is stipulated that in addition to ethanol, the content (mass fraction) of other organic oxygenates in vehicle ethanol gasoline (E10) (VIB) shall not exceed 0.5% and shall not be artificially added; on September 13, 2017, 15 ministries and commissions including the National Development and Reform Commission jointly issued the The Notice on the Implementation Plan for Expanding the Production of Biofuel Ethanol and Promoting the Use of Ethanol Gasoline for Vehicles” de...
