Description
Technical field
The present invention is a kind of aromatisation device of carbon four, and in particular to carbon four and naphtha are the aromatisation of raw material after a kind of ether
The device of clean gasoline processed.
Background technology
Naphtha and the non-hydrogen of carbon four the modification production light aromatic hydrocarbons technology of Research Institute of Petro-Chemical Engineering, modified ZSM-5 are urged
Agent, with naphtha and carbon four as raw material, using two fixed bed reactors in parallel, catalyst one way cycle 20d or so can be with
Repeated regeneration, property retention is preferable.The technological improvement of new generation coking resistivity of catalyst, coke content is compared with first generation catalyst
Half is reduced, to more than one month, aromatics yield increased one way cycle stretch-out in product.
Research Institute of Petro-Chemical Engineering's naphtha and the non-hydrogen of carbon four modification production light aromatic hydrocarbons technology use refinery part mistake
Surplus light naphthar and mixing carbon four produce relatively low alkene, the clean gasoline moderate compared with low sulfur content, aromatic hydrocarbons and adjust to process raw material
And component, liquefied gas of the by-product based on alkane.The popularization and application of the technology can be the appreciation profit of naphtha and C-4-fraction
With and increasing gasoline yield open up a new way so that for enterprise brings good economic benefit.
The content of the invention
The purpose of this utility model is the device for disclosing carbon four and naphtha aromtization clean gasoline after a kind of use ether.
The device of carbon four and naphtha aromtization clean gasoline after a kind of ether, including feeding line a and feeding line b,
Heating furnace, reactor, weight knockout drum, reaction solution knockout drum, reaction gas compressor, absorption and desorption tower, absorption column bottoms pump, stabilization
Tower passes sequentially through pipeline connection, also including de- heavy aromatics tower, two cold feed pipelines, the de- weight is additionally provided with the reactor
Aromatic hydrocarbons tower is connected with weight knockout drum and stabilizer.
The reactor is one.
The heating furnace is one.
Two cold feed pipelines never enter separated on the feeding line a and feeding line b of heating furnace respectively, and with it is anti-
Device is answered to connect.
In a reactor, the aromatization of carbon four is carried out simultaneously after the isomerization reaction and ether of naphtha.One is
The endothermic reaction, one is exothermic reaction, in order to control reactor batch temperature, using carbon after ether four or naphtha as it is cold enter
Material, can effective controlling reaction temperature, it is ensured that the generation of product.
De- heavy aromatics tower is set, when reactor product arene content is high, by the de- heavy aromatics tower of product feeding, is pressed in and steamed
Vapour is used as de- heavy aromatics tower reboiler thermal source.When reactor product arene content is low, product can not enter de- heavy aromatics tower, warp
Stabilizer is sent directly into after heat exchange, technological process is saved.
