In 2002, Yuanzheng Company designed and built * sets of self-priming liquid-phase catalytic hydrogenation units for customers to produce benzocaine, EDB, and EHA, with a history of 15 years. So far, we have designed and manufactured over 350 sets of self-priming gas-liquid reaction devices or core reactors for liquid-phase catalytic hydrogenation, oxidation, carbonylation, alkylation, etc. We have accumulated a wealth of technology and experience and can provide customers with key equipment or complete production facilities for gas-liquid reactions.

These operating devices or key equipment are mainly used in the chemical and pharmaceutical industries, with a core reactor volume of up to 38m ³, a maximum reaction pressure of 20.0MPa, and a maximum reaction temperature of 300 ℃. According to the different requirements of investment scale, production capacity, process and equipment, more than 90% of gas-liquid reactors and devices are produced intermittently, while the remaining less than 10% are produced continuously. In recent years, with the continuous improvement of technology, the proportion of continuous production equipment is gradually increasing.

The advantages of the original gas-liquid reaction device technology are mainly reflected in: 1. Equipped with a self-priming stirred gas-liquid reactor; 2. High speed magnetic seal with a rotational speed of 450-1450rpm; 3. Built in hollow heat exchange plate; 4. Catalyst sedimentation separation, membrane separation, and magnetic separation systems; 5. Optimized process flow and supporting automation control system. With these technical guarantees, the device has the characteristics of fast reaction speed, no amplification effect, strong heat transfer capacity, high production capacity, convenient catalyst application, low consumption of raw materials and catalysts, low operating energy consumption, low solvent usage, leak free sealing, safety and reliability, easy cleaning, and convenient maintenance.
