Agitators for Storage Tanks (Crude and Refined Oil)

The storage of crude oil is the beginning of the process in the petrochemical industry. During this storage, mixing tasks such as BS&W (Basic Sediment & Water), heat transfer and homogenization have to be performed. With our know-how in the field of side-entry agitators, supported by CFD analyses (Computational Fluid Dynamics), EKATO offers fixed and swiveling agitators, which enable efficient and highly effective recirculation.

…and EKATO is at the mix in terms of mobility, heat, petrochemicals, lubricants and bitumen.

In oil storage tanks, EKATO relies on proven technology and can build on more than 85 years of experience. On request, the design can also be confirmed by CFD (Computational Fluid Dynamics) numerical flow simulation.

For mixing tasks like effective mixing of crude oil considering and controlling the sand and water content, BS&W (bottom sludge and water / base sediment and water), mixing of different crude oils, a constant temperature distribution in the tank or for the mixing of refined oils, EKATO provides the appropriate solutions.

The swiveling EKATO side-entry agitator for crude oil storage tanks is a compact, state-of-the-art technology. It uses a single or double mechanical seal system according to API 682, modified for agitators. It represents a reliable solution for the oil and petrochemical industry. Manual adjustment on site or automatic positioning in the process control system (PCS) are available options to swivel the agitator.

Our operational experience in the field of side-entry agitators, together with computational fluid dynamics (CFD) simulations, allows us to determine the optimum number and orientation of agitators around the tank circumference. Reliable, easy-to-maintain, and economical operation are the main benefits based on our knowledge and know-how of side-entry agitators.

With our new test tank with a tank diameter of 3.2 m, a height of 1.74 m and a total volume of 14 m³, an improved scale-up to operating scale has been realized. Up to 10 side-entry agitators can be operated, and the behavior of crude oil can be investigated in depth. Optionally, the scale-up design can be confirmed with a CFD analysis.
