Industrial Stirred Reactor for Chemical Synthesis and Polymerization

An industrial stirred reactor is a process vessel equipped with a mechanical stirring system, used to promote chemical reactions, mixing and heat transfer on a large scale. It serves to precisely control the conditions of reactions such as synthesis, polymerization, hydrolysis and neutralization, ensuring the homogeneity of the reagents and the efficiency of the process.

In a stirred reactor, it is possible to carry out a wide range of chemical reactions, including organic and inorganic synthesis reactions, polymerization (radical, condensation, etc.), neutralization of acids and bases, hydrogenation, oxidation and fermentation. The versatility of the equipment allows it to adapt to different kinetics and operating conditions.

Agimix guarantees the homogeneity of reagents through the appropriate selection and sizing of the agitation system, which may include vertical agitators, lateral or Dual Motion, combined with impelidores specific for each application. The vessel design and baffle position are also optimized to maximize mixing and avoid dead zones.

Thermal exchange control is crucial in a stirred reactor to maintain the reaction temperature within the ideal range, preventing runaway reactions, degrading products or forming unwanted by-products. Jacket, half-pipe or internal coil systems allow heating or cooling the reactor contents with precision, guaranteeing the safety and quality of the process.

Agimix's stirred reactors are manufactured with high-quality, corrosion-resistant materials, such as AISI 304, 316L, Duplex, Super Duplex stainless steel and special alloys such as Hastelloy. The choice of material depends on the nature of the chemicals to be processed and the operating conditions, ensuring the integrity of the equipment and the purity of the product.

Yes, Agimix designs and manufactures stirred reactors for both batch processes (where the reaction occurs in discrete batches) and continuous processes (where reactants are fed and products are removed continuously). The reactor configuration, including the agitation system and inlet/outlet points, is adapted to optimize each type of operation.

Yes, it is completely possible to integrate an Agimix stirred reactor into a complete process skid. This offers a modular, pre-assembled solution, which includes not only the reactor, but also pumps, heat exchangers, instrumentation and control systems, facilitating installation and optimizing space in the industrial plant.

The most common impeller types for stirred reactors in the chemical industry include propellers (for low viscosity), Rushton turbines (for high shear rate and dispersion), anchors (for high viscosity and wall scraping), paddles and Cowles discs (for dispersing and mixing solids). The choice depends on the viscosity of the fluid, the need for shear and the purpose of mixing.

Choosing the ideal stirred reactor involves considering factors such as batch volume, reactant properties (viscosity, density, corrosivity), operating conditions (temperature, pressure), type of reaction and heat exchange requirements.
