Selection of reactor

I know there are two types of reaction vessels, those made of glass and those made of enamel. Here are the differences between them; either type should work fine, as the chemicals involved aren’t very corrosive. Both types of reaction vessels are designed to be corrosion-resistant. Enameled steel involves pre-sintering a layer of glass inside a metal tank, while enamel involves sintering a layer of ceramic to provide resistance to chemical corrosion. The manufacturing processes and material costs for glass-lined steel and enamel are different, which results in some price differences. Enameled steel reactors cannot be used with alkaline materials, as the glass will be dissolved by alkalis and corroded; whereas enameled reactors can be used with both acids and alkalis. Introduction to reaction vessels Reaction vessels are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to carry out processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, including reactors, reaction kettles, decomposition pots, and polymerization tanks ； The materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys, and other composite materials ； Classification of reaction vessels Based on their construction, reaction vessels can be divided into three main categories: open flat-top reaction vessels, open butt-welded flange reaction vessels, and closed reaction vessels. Each type has its own range of applications as well as advantages and disadvantages. 　　Depending on the sealing type of the reactor, they can be classified into packing seal, mechanical seal, and magnetic seal. 　　The reaction kettle consists of a kettle body, a kettle cover, a jacket, an agitator, a transmission device, a shaft sealing device, supports, etc. The types of agitators generally include anchor type, paddle type, turbine type, propeller type, or frame type. When the height-to-diameter ratio of the agitator is large, multiple layers of agitator blades can be used, or options can be selected according to the user’s requirements. A jacket can be installed outside the kettle wall, or heat exchange surfaces can be provided inside the vessel; heat exchange can also be achieved through external circulation. Heating methods include electric heating, hot water heating, heat transfer oil circulation heating, far-infrared heating, and external (internal) coil heating, while cooling methods are jacket cooling and coil cooling inside the tank; the type of stirring blades is also a factor to consider. Support seats include supported types or lug types, etc. A gear reducer is recommended when the rotation speed exceeds 160 revolutions per minute. The number of openings, their specifications, or other requirements can be designed and manufactured according to the user’s needs

And now, if one is to choose the type of reactor based on an epoxidation reaction, what criteria or basis should be used for that choice? Thank you! ! !
