Side-entry mixing systems that can be designed to ATEX and Ex-proof requirements, for sludge prevention, homogenization and blending in large-scale crude oil, fuel oil and biodiesel storage tanks. Field-referenced engineering.
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 at large-scale crude oil terminals: motors that can be designed to ATEX and Ex-proof requirements, seals that can be designed to API 682 requirements and long-shaft designs ensure reliable operation in tanks up to 100,000 m³.
We can design motors, gearboxes and electrical panels to ATEX requirements for Zone 1 or Zone 2; safe operation in hydrocarbon atmospheres.
Double cartridge mechanical seals that can be designed to API 682 requirements, 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; integrated motor that can be designed to ATEX requirements and double cartridge seal.
