Tubular reactors are also divided into many types. Each type has different characteristics and application fields, but they are applicable to liquid-phase reaction, gas-phase reaction and pressurized reaction. The following is a detailed introduction:

① The straight tube reactor is divided into horizontal reactor and vertical reactor. The characteristics of horizontal reactor are suitable for gas phase and liquid phase, which are easy to manufacture and maintain.

② The vertical reactor is suitable for liquid phase hydrogenation reaction, liquid phase oxidation reaction and other processes.

③ The coil type reactor is made of the tubular reactor into a coil type. The equipment is compact and space-saving, which is convenient for maintenance and cleaning. The coil type reactor is made of many water bottle coils which are overlapped and connected in series from top to bottom. Each coil is connected by many semicircular tubes with different radii to form a spiral form. Space is left in the middle of the spiral to facilitate installation and maintenance.

④ The multi tube reactor has a large heat transfer area, which can be applied to the process with large thermal effect, and also to the gas-solid and liquid-solid heterogeneous catalytic reaction process. The reaction tube of the multi tube reactor can also be filled with solid particles to improve the flow of liquid or promote the good contact of heterogeneous fluid, and can be used to store heat so that the reactor can better control the temperature.

⑤ Baffles or stirring devices are set in the tubes of the U-shaped tubular reactor to strengthen the process of heat and mass transfer. The large diameter of the U-shaped tube and the increase of the residence time of materials can be applied to the slow reaction of reaction objects.

When selecting a tubular reactor, you can select a suitable equipment after a thorough understanding of the above contents, which can not only save time, but also reduce costs.
