Internal and External Floating Roof Tank
KDT INDUSTRY specializes in the design, manufacturing, and installation of internal floating roof tanks and external floating roof tanks, essential storage solutions for petroleum products such as crude oil, condensate, and volatile liquids. These atmospheric storage tanks feature floating roofs that rest directly on the liquid surface, significantly reducing evaporation losses and limiting harmful vapor emissions.
What Are Floating Roof Tanks?
Floating roof tanks are cylindrical steel shell tanks equipped with a floating roof that moves vertically with the liquid level. They are widely used in the oil & gas, chemical, and petrochemical industries for the efficient and environmentally friendly storage of large volumes of liquid hydrocarbons.
Internal Floating Roof Tanks
Internal floating roof tanks combine a fixed dome roof on the outside with a floating deck inside the tank. The internal floating roof floats on the liquid surface, drastically minimizing vapor space and reducing evaporation losses by up to 85-90%. Typically constructed with lightweight, corrosion-resistant materials like aluminum and stainless steel, these tanks offer excellent environmental protection and operational economy.
- Significant reduction in product evaporation and VOC emissions
- Separation of stored liquid and air reduces fire and explosion risk
- Prolongs the service life of the tank by reducing corrosion
- Ideal for storing high-value fuels such as gasoline, jet fuel, and toxic chemicals
- Enhanced environmental safety and compliance with regulations
External Floating Roof Tanks
External floating roof tanks feature a floating cover directly exposed to the atmosphere, rising and falling with the liquid level. These tanks are commonly used for storing volatile petroleum products like crude oil, fuel oil, and kerosene. They are available in various configurations including single deck, double deck, steel tray, floating cabin, and aluminum alloy sandwich structures.
- Cost-effective single deck design widely used in industry
- Flexible floating roof support legs suspended in liquid
- Central drain systems prevent water accumulation on the roof
- Rim seal systems effectively reduce rim evaporation
- Designed to prevent tank shell “chucking” during operation
- Best suited for large crude oil storage applications
Environmental and Operational Advantages
Both internal and external floating roof tanks help control vapor emissions of volatile organic compounds (VOCs), minimizing environmental impact and enhancing safety. Internal floating roofs provide additional gas venting control to safely release explosive gases, ensuring regulatory compliance and workplace safety.
