Currently, many companies carry out hydrogenation reactions on a batch basis; this approach proves troublesome when high production volumes are required, and it is also not possible to ensure that the quality of each batch is completely consistent. If we can accelerate the reaction and mass transfer of the materials while ensuring quality, continuous operation can definitely be achieved. A loop reactor is a type of jet membrane reactor used for the continuous catalytic hydrogenation to produce aromatic amines. Jet membrane reactors feature good self-mixing properties, efficient mass transfer, a compact structure, low energy consumption. The catalyst is added once and then reused automatically; only small amounts need to be replenished as required, with corresponding small amounts being discharged. The advantage of this hydrogenation reduction technology is its ability to achieve continuous production with high efficiency. In addition, it features a high degree of automation and strong adaptability, making it suitable for flexible production; it can be configured with two or three reactors in series as needed. It can be used not only in hydrogenation reactions but also in most gas-liquid and liquid-liquid mixing reactions such as alkylation, oxidation, amination, and chlorination. The advantages of this technology are low investment costs, energy efficiency, and reliability. The main equipment for this technology used to rely on imports; by building on advanced foreign technologies, we have fully mastered the technical approach for continuous hydrogenation using loop reactors. At present, we are able to design and manufacture on our own; our strategic partner suppliers produce according to the designs we provide. As a result, the total investment is only two-thirds of that of the original imported units, and it is even lower for some of these units.
