Every vessel is part of a bigger process.

Equipment, utilities and material flows set the limits of production. Start with the system you want to understand.

Independent stock footage; the locations shown are not Acatian customer projects. The overlay and 3D model use a synthetic evaporation example, not measurements from these facilities. Basis: 1,000 kg feed, 10% solids, 25 → 80°C, single-effect evaporation. Inspect the calculation basis. Footage: 8K and Miguel Guerra / Pexels.

Vessel study
Illustrative production-scale stirred bioreactors Three stainless steel vessels share an elevated service platform and pipe headers. The central vessel has an optional section showing a shaft, three impellers, baffles and an air sparger. Vessel size is 200 cubic metres; agitation is medium and aeration is low. These are illustration settings, not process predictions. BR-103 BR-101 BR-102
Illustrative vessels. Controls change the visual; no process performance is predicted.
Drive and impellers

A single drive turns the shaft and its impellers. Impeller configuration, power and mixing time need a process-specific design basis.

Try a mass + energy balance

Try a calculation

Concentrate a food process stream.

Change the solids target and calculate how much concentrate, evaporated water and heating duty the process requires.

Calculation basis and limits

One aqueous stream with fully retained, nonvolatile solids. Feed 25°C; boiling temperature 80°C; heat capacity 4.18 kJ/(kg·K); water latent heat 2,300 kJ/kg; steam economy 1; thermal efficiency 100%. Sensible heating and evaporation are calculated separately. This screening example excludes boiling-point elevation, fouling, product degradation and equipment sizing.

The application uses the same evaporation calculation. The separate CHO reference case provides a complete set of downloadable inputs and numerical checks.

Reference model and scope

The 2,000 L fed-batch example includes model inputs, time profiles, sensitivity results and calculation checks. AC-REF-MAB-FB-001 is a synthetic screening example, not a customer-validated process.
