3-Reactort Continuous Stirred-Tank Reactor

3. A two‑reactor continuous CSTR (Continuous Stirred Tank Reactor) is a reaction system composed of two continuously stirred tank reactors connected in series, commonly used in chemical reaction processes in fields such as chemical engineering. It is widely applied in petrochemicals, fine chemicals, and other related industries. For example, in the synthesis of ethyl acetate, a two‑reactor continuous CSTR can be employed: acetic acid and ethanol undergo an initial reaction in the first reactor under sulfuric acid catalysis, followed by a subsequent step in the second reactor to further increase the conversion rate. In polymerization reactions, it can also be used to produce high‑molecular‑weight materials such as polyvinyl chloride, where different reaction conditions in the two reactors are utilized to control the molecular weight and structure of the polymer.

The system boasts a compact structure and convenient operation.

Dynamic Tubular Reactor

The Dynamic Tubular Reactor is a piece of equipment used for chemical reactions, featuring a unique structure and operational characteristics. It is particularly suited for continuous-flow reactions where solid precipitates are formed during the reaction process.  Reactants enter the tubular reactor at a constant flow rate from one end; as they flow through the pipe, chemical reactions take place, and the reaction products exit from the other end. Unlike conventional tubular reactors, the dynamic tubular reactor may induce dynamic changes in the reaction system through various means—such as adjusting flow rate, temperature, or pressure—or by employing special designs that generate periodic disturbances or oscillations within the fluid inside the tube, thereby enhancing the reaction process.

Plate-type Flow Photoreactor

The plate‑type flow photochemical reactor is a novel reaction device that integrates the structural design of plate reactors with continuous flow technology, while leveraging the principles of photochemistry. The following will explore its structure, operating principles, advantages, and applications. In a plate‑type flow photochemical reactor, light of a specific wavelength emitted by the light source is focused or uniformly distributed throughout the plate‑shaped microchannels via an optical system. Driven by a micro‑pump, the reactants enter the microchannels at a constant flow rate, forming a thin‑layer flow that significantly increases the contact area between the reactants, the photocatalyst, and the light. Reactant molecules excited by light come into contact with the catalyst within the channels, generating active intermediates such as free radicals and holes, which in turn trigger photochemical reactions including oxidation, reduction, or substitution.
