How to Size an LPG Storage Tank for Your Facility

Industrial facilities tend to consume large volumes of LPG. A tank, which is too small, will require frequent refills and can bring about vaporization issues, especially in cold temperatures. On the other hand, an oversized tank may tie up valuable capital and occupy more space than necessary. Additionally, underestimating your gas needs can result in non-compliance with regulatory requirements, leading to fines or safety violations. That is why any gas storage design should be based on data and not assumptions.

The correct LPG tank capacity ensures you always have enough fuel on-site to meet both baseline and peak demand, while keeping delivery intervals manageable. This improves energy planning, minimizes disruptions, and enhances safety.

Choosing the right LPG tank capacity is not simply about estimating how much gas you use on a typical day. It involves a careful analysis of several interrelated factors:

Daily and Peak Gas Consumption

Calculate both average daily usage and peak demands. If your operations fluctuate, your tank should be large enough to handle those high-consumption periods without risking supply interruptions.

Refill Frequency

How often can you realistically accept gas deliveries? Some industrial sites in remote locations may only have access to refills on a weekly or monthly basis. Your LPG bulk storage tank should be sized to hold enough gas between refills, with additional buffer for emergencies.

Climate Conditions

Cold temperatures slow down the vaporization rate of LPG. In regions with harsh winters, your tank might need to be larger or equipped with vaporizers to maintain consistent pressure and flow.

Available Space

Your site may have restrictions on the footprint available for the tank. Horizontal cylindrical tanks require more surface space, while vertical models need less ground but more height clearance.

Regulatory Compliance

Each country or region has specific regulations regarding LPG storage tank placement, size, and pressure limits. Sizing must conform to local codes to ensure safety and legal compliance.

Using an LPG tank size calculator can help bring precision to the sizing process. These calculators typically ask for data such as average daily gas consumption, desired storage autonomy, LPG density, and refill intervals. The result is an estimated minimum tank size based on your actual needs.

However, while calculators are a useful starting point, they should not be your only reference. Their accuracy depends entirely on the quality of the data entered. It is always best to have the results verified by an expert in industrial LPG tank systems before finalizing your choice.

Let us review some general LPG tank sizing guidelines for various industries. These ranges are approximate and should be confirmed with professional calculations. Each case is different. For instance, a facility running around the clock with peak loads will require larger storage than one operating only 8 hours a day.

Industrial LPG bulk storage tanks come in both above-ground and underground formats. Above-ground tanks are easier to install and maintain. They are also typically more cost-effective and offer easier access for inspections. However, in colder environments, they may require thermal shielding or external vaporizers to ensure gas pressure remains stable.

Underground tanks offer better protection from weather conditions and are often preferred in urban environments or sites with limited surface area. Though they involve more complex installation and higher upfront costs, they can offer long-term benefits in terms of safety, aesthetics, and temperature stability.

When choosing between these configurations, considerations such as space constraints, climate, and local regulations must guide the decision. Regardless of type, proper safety clearances, fire protection systems, and access for delivery and maintenance must be incorporated into the gas storage design.

A well-sized LPG storage tank brings numerous operational benefits. 

• Operational continuity. No interruptions from gas shortages.

• Lower delivery frequency. Reduces transport and administration costs.

• Enhanced safety. The right pressure range and vaporization support.

• Scalability. Allows for future growth and increased usage.

• Regulatory compliance. Complies with local codes and insurance policies.

First, it ensures a consistent and uninterrupted fuel supply, minimizing the risk of downtime. This is crucial for industries that rely on constant thermal energy or power output. Second, larger tanks reduce the frequency of deliveries, which can lower overall transportation outgoings and decrease carbon emissions from logistics.

Additionally, proper sizing improves overall safety. Operating a tank within its optimal pressure and fill levels minimizes risks associated with overpressure or low vaporization rates. A right-sized tank also supports business scalability by allowing for future production growth without immediate infrastructure upgrades.

From a compliance standpoint, correctly sized tanks reduce the possibility of regulatory violations. By meeting legal requirements for spacing, volume, and pressure management, companies can avoid fines and maintain safe working environments.

In order to size an industrial LPG tank accurately, certain data must be collected and analyzed. This includes your facility’s average and peak gas consumption, expected duration between refills, climate conditions at the site, available land for installation, and applicable regulatory requirements. Additionally, the specific LPG composition used, whether it is propane, butane, or a blend, can influence density and vaporization rates, which affect tank volume.

Collecting this information in advance helps avoid miscalculations and ensures that the chosen LPG tank capacity aligns with your operational, logistical, and compliance needs.

While tools like an LPG tank size calculator can get you started, it is essential to work with specialists in gas storage design. Industrial systems are complex, and a one-size-fits-all approach doesn’t apply. An expert will assess your operations, review site conditions, and design a safe, cost-effective solution that meets your specific needs.
