The new high-efficiency and energy-saving multi-functional mixing reaction equipment is a tubular reactor with a large aspect ratio and a continuous operation with a static mixer as a unit. It is very suitable for various fast and slow reactions, polymerization, condensation. , sulfonation, nitration, chlorination, nitridation and other reactions. It has been widely used in petroleum, chemical, pharmaceutical, pesticide, fuel, environmental protection, and polymer chemical production. It is very convenient to control energy changes, pressure, and medium flow during the reaction process, especially under high temperature, high pressure, and high viscosity conditions. , The control of flammable, explosive and toxic media is safe and reliable, and has the advantages of high efficiency, low energy consumption, stable reaction without dead angle, easy operation, safety and no leakage.
The high-efficiency and energy-saving new hybrid reaction equipment developed and produced by our company has been well applied in the following fields and projects.
1. 2000 tons/year oil phase and water phase reaction pipeline of a pharmaceutical chemical intermediate project in Nanjing
The medium of this reactor is A, B, C three kinds of medium. First, A and B are premixed evenly; secondly, the AB mixture is mixed with C evenly; thirdly, the ABC mixture is heated (the temperature rises to the temperature required by the process); fourth, it enters the reaction section (to ensure the reaction The body is in the required temperature and pressure range); fifth, the cooling section.
2. Mixed reactor (chlorination reactor) of ethylene direct chlorination project of a company in CNOOC Shandong
The medium of this reactor is ethylene dichloride (A), chlorine gas (B) and ethylene (C). First, use the ejector as a distributor to absorb B by A, and then enter the mixer to mix evenly; second, use the ejector as a distributor to absorb C from A, and then enter the mixer to mix evenly (this process is synchronized with the first); Third, the AB and AC mixtures enter the mixed reaction section for mixed reaction; fourth, after entering the reaction section, the reaction is completed after a certain period of time, and the expected conversion rate is achieved (to ensure that the reactant is in the required temperature and pressure range); fifth, Enter the next process.
3. 120,000 tons/year TMP mixed reaction unit of a company in Deyang, Shandong
The material properties are as follows:
4. 800,000 tons/year liquid alkylation process unit reactor in a research institute of the Chinese Academy of Sciences
Brief description of the reaction process: The circulating acid and circulating hydrocarbons are fully mixed by the pump to form an emulsion and then enter the reactor. The mixed olefin and the emulsion are fully mixed and reacted at the inlet of the reactor. The reaction is carried out at a lower temperature (about 5ºC), Most of the reacted mixture is recycled back to the inlet of the reactor, and a small part is recovered as a product.
The reaction process is a liquid-liquid immiscible reaction between two phases. Due to the large density difference between the acid phase and the hydrocarbon phase (acid/hydrocarbon is about 3.0), and the solubility of the hydrocarbon phase in the acid phase is very small, the surface tension of the acid phase is large. , the acid and hydrocarbon are easily separated after mixing (the acid-hydrocarbon emulsion starts to appear obvious layering within 1min), so this reaction requires strong mixing.
5. Mixed reactor (sulfonation reactor) of a sulfonation unit of a chemical company in Zhejiang
The medium of this reactor is sulfonate (A) and chlorine gas (B). First, A and B are pre-mixed through a special distributor; second, the AB mixture enters the reaction section for reaction (two reactors are a group of reaction sections); third, the upper group of reactants and B are pre-mixed through a special distributor ; Fourth, the reactant mixture enters the reaction section for reaction; fifth, the reaction process of the third and fourth parts is repeated.
