Bio-heavy oil tank sludge cleaning and conversion of sludge into high-calorific solid fuel technology |
Sludge buildup on the bottom of a biofuel tank is a common problem that can affect the quality of the stored fuel, reduce storage capacity, and potentially cause operational problems for the tank and associated piping systems. Regular inspection and maintenance is important to ensure tank performance, integrity, and compliance with environmental and safety regulations. Sludge Removal: Over time, bio-heavy oil can form sludge due to the settling of heavier organic compounds, water and other contaminants. This sludge must be removed regularly to maintain the quality of the oil and the effective storage capacity of the tank. Cleaning: Tanks must be cleaned to remove any residue that could corrode the tank or contaminate the stored oil. Cleaning is done by mechanical means, chemical cleaners, or a combination of the two, depending on the tank design and the type of sludge. Periodic Inspection: Tanks should be inspected periodically to assess structural integrity, detect corrosion or damage, and ensure that all components, such as vents, gauges, and seals, are functioning properly. Emptying the tank: A thorough inspection, especially an internal inspection, usually requires emptying the tank. This allows the inspector to enter the tank in accordance with appropriate safety protocols and perform a detailed inspection of the tank internal surfaces, welds, and structural components. Inspection Cycle: Tank age and condition: Older tanks or tanks showing signs of wear or corrosion, and the characteristics of the fuel, such as the rate of sludge formation, may require more frequent inspections. Typically, external inspections can be performed more frequently (e.g., annually or semi-annually), while a comprehensive internal inspection may be required every 5 to 10 years. |
Bio-fuel tank sludge (sludge of bio-fuel) Fluidization of sludge
< Tank Cleaning Step >
Preparation for cleaning: Drain as much bio-fuel as possible inside the tank. (Pump out as much of the heavy fuel oil as possible in the sump, excluding the sludge.)
1. Maintain and heat the tank bottom temperature with a heating coil (70~90℃)
2. Inject QuickClean-MK emulsified detergent (20% dilution)
3. Circulate the fluidized sludge with a diaphragm pump and create a water flow.
4. Inject steam injection into the unfluidized sludge under the Heating Coil and in the corners to release it.
5. Discharge the fluidized sludge with a vacuum car and rinse the small amount of residue with a high pressure washer to complete the cleaning process.
