Description
Technical field
The present invention relates to chemical industry, in petrochemical complex, need the reactor of two-phase good contact, particularly relate to a kind of device for alkylate oil synthesis.
Background technology
The stop bracket gasoline harmonic component that C4 alkene and Trimethylmethane through the technical octane that alkylated reaction generates are is main component with various trimethylpentane, the advantages such as the vapour pressure that technical octane has high-octane rating, the noxious products that burns is few and lower.Alkylated reaction can be divided into alkyl sodium sulfate metallization processes and hydrofluoric acid alkylation technique according to used catalyst difference, hydrofluoric acid is volatile hypertoxic pharmaceutical chemicals, serious harm will be caused to environment and production once reveal, and alkyl sodium sulfate metallization processes main drawback to be the quantity discharged of spent acid larger.China's many employings alkyl sodium sulfate metallization processes, it is generally acknowledged that the rate-determining steps determining sulfuric acid alkylation technological reaction speed is the mass transfer of alkane to acid, therefore in alkyl sodium sulfate metallization processes, the contact situation of sour hydrocarbon is extremely important operational variable.The main alkyl sodium sulfate metallization processes of order first two is the effluent refrigeration-type sulfuric acid alkylation reaction process of Stratco company of the U.S. and the cascade reactor alkyl sodium sulfate metallization processes of Kellogg company of the U.S., these two kinds of techniques all fail to reach desirable sour hydrocarbon exposure level, greatly limit speed of reaction, add reactor size.In addition alkyl sodium sulfate metallization processes or a strong exothermal reaction, temperature of reaction rising can make by product increase, and affects alkylate oil quality.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of device for alkylate oil synthesis that can solve sour hydrocarbon contact problems and exothermic heat of reaction problem in alkyl sodium sulfate metallization processes is provided.
Technical scheme of the present invention is summarized as follows:
A kind of device for alkylate oil synthesis, comprise reactor body 1, the bottom of reactor body is provided with reaction-ure feeding mouth 9, the bottom of reactor body is provided with vitriol oil opening for feed 8, the middle part of reactor body is provided with sulfuric acid discharge port 3, the middle and upper part of reactor body is provided with liquid phase discharge port 7, the top of reactor body is provided with gas phase discharge port 6, the middle and lower part of reactor body inside is provided with packing layer 2, make the upper surface of packing layer between sulfuric acid discharge port 3 and liquid phase discharge port 7, make the lower surface of packing layer between vitriol oil opening for feed 8 and reaction-ure feeding mouth 9, liquid distributor 11 is provided with below packing layer, reaction-ure feeding mouth 9 is connected with liquid distributor 11 by pipeline, between liquid phase discharge port 7 and gas phase discharge port 6, mist eliminator 4 is provided with in reactor body inside.
The preferred Pall ring filler of filler or ring intalox filler.
The preferred tubular liquid sparger of liquid distributor, disc type liquid distributor or shower nozzle type liquid distributor, also can select other conventional liquid distributor.
Advantage of the present invention is: a kind of device for alkylate oil synthesis has better sour hydrocarbon contact effect, accelerate speed of reaction and reduce alkane alkene ratio simultaneously, and strictly can control temperature of reaction, reduce the generation of byproduct of reaction, thus improve the quantity and quality of alkylation synthetic oil, and the energy consumption needed for Trimethylmethane circulation can be reduced.
Accompanying drawing illustrates:
Fig. 1 is the device schematic diagram for alkylate oil synthesis.
