Description

TECHNICAL FIELD

[0001] The utility model relates to methyl tertiary butyl ether recycling technical field, especially in a kind of methyl tertiary butyl ether recycling treatment device. BACKGROUND

[0002] MTBE is the English abbreviation of methyl tertiary butyl ether, at present, due to the large change of dehydrogenation reaction product components during the start and stop of isobutane dehydrogenation device, especially the content of isobutene, which will directly cause the fluctuation of downstream MTBE unit to be larger, so that a large number of unqualified MTBE will appear, and C4 and methanol in unqualified MTBE are more, most of the oil refining enterprises will be directly used for blending gasoline, but this technology will cause the octane number of gasoline to be low, and the benefit of enterprise will also be affected.

[0003] In the patent with publication number CN205590589U, a methyl tertiary butyl ether unqualified product recycling system is provided, which includes a methyl tertiary butyl ether storage tank, an etherification reactor, a centrifugal pump, a recycling pipeline, a mixing pipeline, a catalytic rectification tower, a feed preheater and a pressure controller. A pressure controller 8 is arranged between the outlet end of the etherification reactor 2 and the mixing pipeline 5. The pressure can be controlled by the pressure controller 8 to control the vaporization temperature, so as to control the material gasification rate and the flow rate, so as to ensure that the gas phase material also enters with the liquid phase material and exits, and at the same time, the reaction temperature is controlled by using partial material gasification, which not only saves energy but also avoids catalyst blockage to cause pressure drop to rise. During production, the unqualified MTBE produced by the MTBE unit is stored in the methyl tertiary butyl ether storage tank 1, and then a centrifugal pump 3 (with a maximum flow of 15 cubic meters per hour, a head of 177 meters and a motor power of 15 KW) is installed in the tank area. The inlet of the centrifugal pump 3 is connected to the methyl tertiary butyl ether storage tank 1, and the outlet of the centrifugal pump 3 is connected to the outlet pipeline of the etherification reactor 2. The unqualified MTBE is transported into the recycling pipeline 4 by the centrifugal pump 3. The reaction products in the etherification reactor 2 are preheated, and then the recycled unqualified MTBE is mixed with the reaction products of the etherification reactor 2 and enters the mixing pipeline 5, and finally enters the catalytic rectification tower 6 for separation of light and heavy components. After mixing, the composition of the mixture, especially the molar fraction of methanol, must be ≤0.049% (the pressure of the catalytic rectification tower is 0.5 PMa). If there is too much methanol, the remaining C4 and methanol cannot form azeotrope, and part of the methanol may cause the MTBE at the bottom of the catalytic rectification tower to be unqualified. However, the following problems still exist in the patent:

[0004] The existing recycling treatment of unqualified methyl tertiary butyl ether does not have the work of stirring and filtering, and part of the impurities in the methyl tertiary butyl ether will not be filtered, which will cause the recycled methyl tertiary butyl ether to be impure and need to be recycled again.
