Revolutionizing Oil and Gas Storage: The Innovation of External Floating Roof Tanks

The oil and gas industry, a cornerstone of global energy supply, faces the ongoing challenge of safe, efficient, and environmentally responsible storage of liquid hydrocarbons. External Floating Roof Tanks (EFRTs) have emerged as a pivotal innovation, significantly enhancing storage capabilities and mitigating environmental risks. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a leader in advanced storage solutions, recognizes the transformative impact of EFRTs and their vital role in modern oil and gas operations.

The Evolution of Liquid Hydrocarbon Storage

Historically, liquid hydrocarbons were stored in fixed-roof tanks, which presented several challenges. Evaporation losses, product contamination, and the risk of fire hazards were significant concerns. EFRTs were developed to address these issues, providing a more efficient and safer storage solution.

What are External Floating Roof Tanks (EFRTs)?

EFRTs are large, cylindrical storage tanks equipped with a floating roof that rises and falls with the liquid level inside. The roof floats on the surface of the stored liquid, minimizing the vapor space above it. This design effectively reduces evaporation losses and the associated environmental and economic impacts.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

Key Features and Benefits of EFRTs:

Reduced Evaporation Losses:

The floating roof minimizes the vapor space, significantly reducing the evaporation of volatile organic compounds (VOCs). This leads to substantial product savings and reduces air pollution.

This is especially important for storing high-volatility products such as gasoline and crude oil.

Enhanced Fire Safety:

By minimizing the vapor space, EFRTs reduce the risk of fire and explosion. The absence of a large vapor space limits the potential for flammable vapor accumulation.

This improves safety for both personnel and the surrounding environment.

Minimized Product Contamination:

The floating roof provides a barrier against rainwater, dust, and other contaminants, ensuring product quality and purity.

This is crucial for maintaining the integrity of stored products.

Environmental Compliance:

EFRTs help oil and gas companies comply with stringent environmental regulations by reducing VOC emissions.

This contributes to a more sustainable and responsible industry.

Operational Efficiency:

EFRTs allow for easier inspection and maintenance compared to fixed-roof tanks.

The floating roof provides access to the tank interior without the need for extensive emptying and cleaning.

Cost-Effectiveness:

While the initial investment in EFRTs may be higher than fixed-roof tanks, the long-term cost savings from reduced product losses and maintenance make them a cost-effective solution.

Reduced enviromental fines also add to the long term cost savings.

Design and Construction of EFRTs:

Center Enamel, with its expertise in advanced storage solutions, understands the critical importance of proper design and construction of EFRTs. Key design considerations include:

Roof Design: The floating roof must be designed to withstand the weight of personnel, equipment, and potential snow or rain loads.

Seal Systems: Effective seal systems are essential to minimize vapor losses between the roof and the tank shell.

Drainage Systems: Proper drainage systems are necessary to prevent rainwater accumulation on the roof.

Stability and Buoyancy: The roof must maintain stability and buoyancy under all operating conditions.

Material Selection: Corrosion-resistant materials are crucial for long-term durability.

Types of External Floating Roofs:

Pontoon Roofs: These roofs consist of a center deck and an annular pontoon around the perimeter.

Double-Deck Roofs: These roofs feature two decks separated by structural members, providing increased strength and stability.

Full Contact Roofs: These roofs are in full contact with the stored product.

Applications of EFRTs in the Oil and Gas Industry:

Crude Oil Storage: EFRTs are widely used for storing crude oil at refineries and terminals.

Gasoline and Other Refined Products: They are essential for storing volatile refined products.

Petrochemical Storage: EFRTs are used for storing various petrochemicals and solvents.

Biofuel Storage: With the rise of biofuels, EFRTs are becoming increasingly important for storing these products.
