ATEX-certified side-entry mixing systems for sludge prevention, homogenization and blending in large-scale crude oil, fuel oil and biodiesel storage tanks. Engineering referenced by JANAF Plc.
In large petroleum storage tanks, long-term holding of crude oil generates bottom sludge (BS&W — Bottom Sediment and Water); paraffin, asphaltene and water phases settle and can plug pipelines. Side-entry mixers — mounted near the tank floor with low-speed axial-flow impellers — prevent this settling and homogenize the product. Mechanimix delivers end-to-end engineering with references such as the JANAF Plc Omišalj terminal: ATEX-certified motors, API 682 seals and long-shaft designs ensure reliable operation in tanks up to 100,000 m³.
Motors, gearboxes and electrical panels certified for Zone 1 or Zone 2; safe operation in hydrocarbon atmospheres.
Double cartridge mechanical seals with Plan 52/53A/53B barrier fluid loops targeting zero emissions.
HM axial-flow impellers at 200–400 rpm create a sweep current across the tank floor that prevents settling.
2–4 mixers arranged angularly on floating- and fixed-roof tanks; CFD dead-zone analysis.
Component ratios monitored online with a blend analyzer; blend recipes managed through SCADA.
Vibration, bearing temperature and seal pressure streamed over IoT for continuous monitoring; predictive maintenance reporting.
This system consists of integrated components selected from MechaniMix's product portfolio.
Low-speed primary mixer mounted on the tank side wall; ATEX motor and API 682 seal integrated.
