Agitation fulfills different requirements in batch-wise or continuously operated reactors: optimum blending of liquid and solid components, mass transfer in multi phase systems and the transfer of the reaction heat.

Mixing in the downstream processing of chemical products in mostly thermal and mechanical operations influences their properties and quality. The control of particle sizes in EKATO crystallizers is facilitated by defined concentration and shear profiles in the slurry. Solid products are dried after crystallization or precipitation: EKATO vacuum dryers result in short process times without detrimental overheating of the product.

The formulation of chemicals to consumer goods often involves the handling of high viscous materials. The ingestion and dispersion of liquids or powders into the viscous bulk is preferably done by the EKATO PARAVISC impeller. This impeller can be combined with wall scrapers or high shear impellers on a separate shaft for flexibility of the operation and maximum homogeneity of the products.

EKATO provides a comprehensive know-how fort he scale up and design of such complex plants. These engineering services include pilot trials in EKATOs R&D lab as well as numerical flow simulations (CFD). The mechanical engineering for all components relies on modern tools as the Finite Element Analysis (FEA), which leads to low investment costs without compromises regarding plant safety and reliability.

EKATO mechanical shaft seals including the seal supply system ensure the reliable operation of the agitator at all pressure levels. With their long service intervals they are easy to maintain, and the automation level to monitor and control the supply can be adjusted to the operation and safety requirements.
