Abstract
The utility model discloses a methyl tert butyl ether nonconforming product freshening system, including methyl tert butyl ether storage jar and etherification reaction ware, the exit end of methyl tert butyl ether storage jar passes through centrifugal pump and freshening pipeline connection, get into the hybrid tube line behind the exit end of etherification reaction ware and the freshening pipeline connection, it is connected with the catalysis rectifying column to mix the exit end of pipeline. The utility model discloses it is rational in infrastructure, can carry out recycle to unqualified MTBE and refine again, can improve MTBE purity, improve product quality, safe and reliable.
Description
Technical field
This utility model relates to the freshening system on a kind of dehydrogenation of isobutane device, is specifically related to a kind of methyl tertiary butyl ether(MTBE) substandard product freshening system.
Background technology
MTBE is the english abbreviation of methyl tertiary butyl ether(MTBE), at present, owing to dehydrogenation of isobutane device products of dehydrogenation reactions change of component during shutting down is bigger, the particularly content of isobutene., the MTBE unit fluctuation ratio that this situation can directly contribute downstream is bigger, thus there will be a large amount of defective MTBE, in defective MTBE, C4 and methanol are on the high side.Most oil refining enterprise all can be directly used in blended gasoline, but this technology can cause octane number on the low side, and the performance of enterprises also can be under some influence.
Summary of the invention
The purpose of this utility model is aiming at the defect that prior art exists, there is provided a kind of rational in infrastructure, defective MTBE can be recycled and refine again, MTBE purity can be improved, improve product quality, safe and reliable a kind of methyl tertiary butyl ether(MTBE) substandard product freshening system.
Its technical scheme is: a kind of methyl tertiary butyl ether(MTBE) substandard product freshening system, including methyl tertiary butyl ether(MTBE) storage tank and methyltertiarvbutyl ether reactor, the port of export of described methyl tertiary butyl ether(MTBE) storage tank is connected with freshening pipeline by centrifugal pump, the port of export of described methyltertiarvbutyl ether reactor enters mixing line after being connected with freshening pipeline, and the port of export of described mixing line is connected with catalytic rectifying tower.
The porch of described methyltertiarvbutyl ether reactor is provided with feed preheater.
It is provided with pressure controller between the port of export and the mixing line of described methyltertiarvbutyl ether reactor.
This utility model compared with prior art, has the advantage that rational in infrastructure, can recycle defective MTBE and refine, can improve MTBE purity, improves product quality, safe and reliable.
Accompanying drawing explanation
It is presented herein below and in conjunction with the accompanying drawings and embodiments this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
In figure: 1. methyl tertiary butyl ether(MTBE) storage tank；2. methyltertiarvbutyl ether reactor；3. centrifugal pump；4. freshening pipeline；5. mixing line；6. catalytic rectifying tower；7. feed preheater；8. pressure controller.
Detailed description of the invention
With reference to Fig. 1, a kind of methyl tertiary butyl ether(MTBE) substandard product freshening system, including methyl tertiary butyl ether(MTBE) storage tank 1 and methyltertiarvbutyl ether reactor 2, the port of export of described methyl tertiary butyl ether(MTBE) storage tank 1 is connected with freshening pipeline 4 by centrifugal pump 3, the port of export of described methyltertiarvbutyl ether reactor 2 enters mixing line 5 after being connected with freshening pipeline 4, and the port of export of described mixing line 5 is connected with catalytic rectifying tower 6.
The porch of described methyltertiarvbutyl ether reactor 2 is provided with feed preheater 7.Reaction mass enters in methyltertiarvbutyl ether reactor 2 after being preheated by feed preheater 7, can be preheated reaction mass by feed preheater 7, it is ensured that reaction temperature.
It is provided with pressure controller 8 between the port of export and the mixing line 5 of described methyltertiarvbutyl ether reactor 2.Pressure can be controlled by pressure controller 8, control vapourizing temperature, thus control material rate of gasification, and control flow velocity, ensure that gaseous phase materials, also with liquid phase material upper entering and lower leaving, uses partial material gasification to control reaction temperature simultaneously, the most energy-conservation but also avoid catalyst blockage to cause pressure drop to raise.
During production, the defective MTBE of MTBE cellular manufacture enters methyl tertiary butyl ether(MTBE) storage tank 1 and stores, then install from tank field centrifugal pump 3(centrifugal pump maximum stream flow 15 side/hour, lift 177 meters, power of motor 15KW), the entrance of centrifugal pump 3 is connected with methyl tertiary butyl ether(MTBE) storage tank 1, the outlet of centrifugal pump 3 is linked on the outlet line of methyltertiarvbutyl ether reactor 2, by centrifugal pump 3, defective MTBE is transported in freshening pipeline 4, after product preheating in methyltertiarvbutyl ether reactor 2, the defective MTBE of freshening enters mixing line 5 after mixing with methyltertiarvbutyl ether reactor 2 product, eventually enter into catalytic rectifying tower 6 and carry out weight Component seperation.The composition of sample analysis mixture is wanted after mixing, the particularly mole fraction of methanol must assure that≤0.049%(catalytic distillation pressure tower 0.5PMa), if methanol is too much, residue C4 and methanol do not become azeotropic mixture, and the MTBE that part methanol is likely to result at the bottom of catalytic rectifying tower tower is defective.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art are possessed, it is also possible to make a variety of changes on the premise of without departing from this utility model objective, and the content after change still falls within protection domain of the present utility model.
Claims (3)
1. a methyl tertiary butyl ether(MTBE) substandard product freshening system, it is characterized in that: include methyl tertiary butyl ether(MTBE) storage tank and methyltertiarvbutyl ether reactor, the port of export of described methyl tertiary butyl ether(MTBE) storage tank is connected with freshening pipeline by centrifugal pump, the port of export of described methyltertiarvbutyl ether reactor enters mixing line after being connected with freshening pipeline, and the port of export of described mixing line is connected with catalytic rectifying tower.
