What is a tubular reactor?

The Tubular Reactor is a new, highly efficient, energy-saving, and multi-functional mixing reactor suitable for rapid reactions, polymerization reactions, exothermic reactions, and those involving flammability or explosiveness, especially under high temperature, high pressure, and high viscosity conditions. The advantages of the tubular reactor lie in its utilization of the static mixer's benefits. It offers more stable reactions, uniform heat release, excellent pressure and high-temperature resistance, and is much more cost-effective compared to batch reactors. With years of engineering experience and continuous improvements, the tubular reactor can be designed with removable components for easy cleaning in systems prone to scaling and crystallization. Additionally, it can be modularly combined to adapt to different process requirements and reaction times.

The Tubular Reactor is a continuous operation reactor with a tubular shape and a high length-to-diameter ratio, utilizing static mixers as its units. It is highly suitable for a variety of fast and slow reactions, polymerization, condensation, sulfonation, nitration, chlorination, and nitriding. The tubular reactor has found extensive applications in the petrochemical, pharmaceutical, pesticide, fuel, environmental protection, and high polymer chemical industries. It offers great convenience in controlling energy changes, pressure, and medium flow during the reaction process, especially under high temperature, high pressure, and high viscosity conditions. It is safe and reliable in controlling flammable, explosive, and toxic media, featuring low energy consumption, stable reactions without dead spots, ease of operation, and safety with no leakage.

The tubular reactor's mixing section can accommodate two types of mixing units, the K-type and X-type mixing units. These mixing units increase the contact area of the fluid, thereby enhancing the heat transfer coefficient (the heat transfer coefficient for gases can be improved by 5-8 times; for heating viscous liquids, it can be increased by 3-5 times; for gas condensation with a large amount of non-condensable gases, it can be improved by 8.5 times; for heat exchange of high polymer melting bodies, it can reduce the temperature and viscosity gradients across the tube cross-section). They also force the fluid within the forced boundary layer to flow towards the center of the tube, which on one hand thins the boundary layer thickness and on the other hand accelerates the fluid within the boundary layer, ensuring thorough and uniform mixing of immiscible liquid phases.
