The new type of high-efficiency, energy-saving and multi-functional mixing reactor is a continuous tubular reactor with large aspect ratio and static mixer unit. It is very suitable for all kinds of fast and slow reactions, polymerization, condensation, sulfonation, nitration, chlorination, nitridation and other reactions. It has been widely used in petroleum, chemical industry, medicine, pesticide, fuel, environmental protection and polymer chemical production. It is very convenient to control the energy change, pressure and medium flow in 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, with high efficiency, low energy consumption, stable reaction without dead angle and easy operation. It is safe and leak-free.

Our company has developed and produced a new type of high-efficiency and energy-saving hybrid reaction equipment which has been well applied in the following fields and projects.

 

1. Oil 2000 t/a phase-to-water reaction pipeline for a pharmaceutical and chemical intermediate project in Nanjing

The medium of the reactor is A, B and C. First, pre-mixing of A and B is uniform; secondly, mixing of AB and C is uniform; thirdly, heating of ABC mixing homogeneous body (temperature rise to the required temperature); fourthly, entering the reaction section (to ensure that the reactor is in the required temperature and pressure range); fifth, cooling section.

 

2. Mixed reactor (chlorination reactor) for ethylene direct chlorination project of CNOOC Shandong Company

The medium of the reactor is dichloroethane (A), chlorine (B), ethylene (C). First, the ejector is used as distributor to absorb B from A and then enter the mixer to mix evenly; secondly, the ejector is used as distributor to absorb C from A and then enter the mixer to mix evenly (this process is the first step); thirdly, the mixture of AB and AC enters the mixing reaction section; fourthly, after entering the reaction section, the reaction is completed in a certain time to achieve the desired conversion rate.( Ensure that the reactor is in the required temperature and pressure range; Fifth, enter the next process.

4. 800,000 tons/year liquid alkylation reactor in a Research Institute of the Chinese Academy of Stone Sciences

Brief description of the reaction process: After the pump circulating acid and circulating hydrocarbon are fully mixed to form an emulsified liquid, it enters the reactor. At the inlet of the reactor, the mixed olefin and the emulsified liquid are fully mixed. The reaction is carried out at a lower temperature (about 5 C). Most of the reacted mixture is recycled back to the reactor entrance, and a small part is extracted as a product.

The reaction process is the reaction between two phases of liquid-liquid interaction. Because the density difference between acid phase and hydrocarbon phase is large (acid / hydrocarbon is about 3), and the solubility of hydrocarbon phase in acid phase is very small, the surface tension of acid phase is larger. After the mixed acid hydrocarbon is mixed, it is easy to separate (the obvious stratification phenomenon appears in the static acid hydrocarbon emulsion 1min), so this reaction needs strong mixing.

 

5. Mixed Reactor of Sulfonation Unit (Sulfonation Reactor) of a Chemical Company in Zhejiang Province

The medium of the reactor is sulfonate (A) and chlorine (B). First, A and B are pre-mixed by a special distributor; secondly, AB mixtures enter the reaction section (two reactors are a group of reaction sections); thirdly, the reactants of the upper group and B are pre-mixed by a special distributor; fourthly, reactant mixtures enter the reaction section; fifthly, the reaction process of the third and fourth parts is repeated.
