Description
Technical field
The invention belongs to petrochemical industry, in particular to a kind of MTBE process units.
Background technique
MTBE is the trade name of methyl tertiary butyl ether(MTBE), is the production that isobutene and methanol react under strongly acidic catalyst effect
Object, it is mainly used for substitution lead tetraethide as dopes for gasoline.
MTBE device is raw material using the mixing C-4-fraction and outsourcing methanol of depropanization device production, with QRE-1, D-
006 large aperture storng-acid cation exchange resin be catalyst, under the action of resin catalyst with mix isobutyl in C4 alkene
Alkene carries out etherification reaction, and reaction generates product MTBE and by-product residue C4.
The MTBE device design of the prior art is to mix in four raw material of carbon isobutene content 18-20% as design basis point.Carbon
Isobutene and industrial methanol in four fractions is taken the photograph using large aperture storng-acid cation exchange resin as catalyst in temperature 40-70
Under family name's degree, pressure 0.7-0.9Mpa operating condition, in mixed phase synthesizing methyl tertbutyl ether (MTBE), which is that reversible heat release is anti-
It answers, at 25 degrees Celsius, two liquid phase reactor heat are -37KJ/mol.By the law of thermodynamics, temperature raising is conducive to accelerate reaction speed
Rate, but be unfavorable for generating MTBE, reaction temperature is lower, and selectivity is better, but reaction speed slows down.To guarantee higher conversion
Rate, but do not make reaction temperature excessively high, General reactions temperature is controlled at 40-70 degrees Celsius.Isobutene content in C-4-fraction
Will cause catalyst reaction cycle time if it is greater than design basis point, reaction temperature and operating pressure increase, and side reaction increases,
Energy consumption increases.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of MTBE process units for being equipped with C4 circular route, Neng Gouyan
Long MTBE device catalyst lifetime reduces the side reaction of MTBE device, reduces production energy consumption.
In order to solve the above technical problems, the MTBE process units of outfit C4 circular route of the invention, including water scrubber, also wrap
Return tank is included, is provided on the unicom pipeline between the water scrubber and the return tank and controls to adjust valve I, the control and regulation
Supplied materials pipeline is also connected on valve I, the return tank is connected with discharge nozzle through reflux pump, and the discharge nozzle is through controlling flow valve group
III connect with the tank field MTBE, and cut is provided with C4 circular route on the discharge nozzle between the reflux pump and control flow valve group III,
The C4 circular route is successively connected through control flow valve group II, check-valves IV, static mixer and head tank；The check-valves
IV, the C4 circular route between static mixer is connect by mother tube with raw material tank field；Control stream is provided on the mother tube
Measure valve group V.
After adopting the above technical scheme, the present apparatus, which goes out cut on device pipeline in by-product residue C4, newly increases a pipeline
It goes in three valve group of material carbon, when mixing that isobutene content is greater than 20% in carbon four, C4 circular route is to raw material valve group after opening ether
Process reduces the high isobutene content of raw material, not only improves conversion ratio, but also plays the role of reducing loss.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the MTBE process units of outfit C4 circular route of the invention.
Specific embodiment
As shown in Figure 1, the MTBE process units of outfit C4 circular route of the invention, including water scrubber 1, further include reflux
Tank 2 is provided on the unicom pipeline between the water scrubber 1 and the return tank 2 and controls to adjust valve I 11, the control and regulation
It is also connected with supplied materials pipeline 20 on valve I 11, the return tank 2 is connected with discharge nozzle 21 through reflux pump 3, and the discharge nozzle 21 is through controlling
Flow valve group III 13 processed is connect with the tank field MTBE, is broken on the discharge nozzle 21 between the reflux pump 3 and control flow valve group III 13
Mouth is provided with C4 circular route 22, and the C4 circular route 22 is successively through controlling flow valve group II 12, check-valves IV 14, static mixer
4 connect with head tank 5；C4 circular route 22 between the check-valves IV 14, static mixer 4 passes through mother tube 23 and head tank
Area's connection；Control flow valve group V 15 is provided on the mother tube 23.
It can be greatly reduced after the present apparatus, in the entire production cycle and be caused due to isobutene content is excessively high in raw material
Catalyst reaction cycle time, reaction temperature and operating pressure increase, and side reaction increases, and energy consumption increases.Rear catalyst is transformed
Service life extended, to improve conversion ratio, reduce by-product, further function as energy-saving, reduce its life
Produce cost.
