Explosion Proof Solvent Storage Tank Equipment for Edible Oil Extraction Plant

Every solvent extraction plant must store a working inventory of hexane or food grade extraction solvent, and this storage step is one of the most safety sensitive parts of the whole line. The Explosion Proof Solvent Storage Tank is designed to hold that inventory in a sealed, grounded and pressure protected vessel so that solvent vapour cannot escape or accumulate to a hazardous concentration.

Our storage tank is fabricated from rolled steel plate with dished ends, internal anti corrosion coating and a full set of safety fittings. A breather valve maintains the internal pressure within safe limits as the tank fills and empties, a magnetic level gauge shows the exact inventory, and grounding bosses bond the shell to the plant earthing system. Optional nitrogen blanketing keeps oxygen away from the vapour space for additional security.

Because the tank is a buffer between the solvent receiving system and the extraction workshop, its size can be matched to daily solvent turnover, from compact five cubic metre day tanks up to one hundred cubic metre central storage vessels. All welds are full penetration and pressure tested, and every unit is delivered with material certificates and a hydro test report.

• Sealed And Grounded: Full penetration welded shell with dedicated grounding bosses keeps both liquid and static charge safely contained.
• Pressure Protection: A calibrated breather valve and emergency vent release any overpressure while preventing air from entering during normal breathing.
• Accurate Inventory: A magnetic level gauge and optional radar transmitter give continuous, reliable reading of the stored solvent volume.
• Corrosion Resistant: An internal protective coating and optional stainless steel construction resist the mildly aggressive grade of commercial extraction solvent.
• Nitrogen Blanketing Ready: Nozzles for nitrogen injection allow the vapour space to be inerted, reducing fire and explosion risk to a minimum.
• Flexible Volume: Standard capacities from 5 to 100 cubic metres meet the daily solvent turnover of both small batch and large continuous plants.

The Explosion Proof Solvent Storage Tank is essential in edible oil solvent extraction plants, chemical and pharmaceutical plants handling flammable solvents, and any facility that receives, stores and dispenses hexane or similar extraction agents. It serves as the main solvent reservoir, as a day tank feeding the extractor and as a receiving vessel for recovered solvent returning from the recovery section.

The tank is shipped with all nozzles and flanged faces capped, the internal surface cleaned and the outside coated with anti rust primer. Manways and fittings are crated separately for container transport. Material certificates, a hydro test report and installation drawings are provided, and the vessel carries a twelve month warranty against manufacturing defects.
