Bolted steel tank

As biogas projects become larger and more sophisticated, storage tanks have become an important part of project planning. However, transporting and installing large tanks can be challenging, especially when a project is located in a remote agricultural area or an industrial site with limited transportation access.

This is where bolted tanks and on-site assembled tanks can provide an effective solution.

What Is a Bolted Tank?

A bolted tank is a modular tank system manufactured using individual panels and structural components. Instead of transporting a complete large tank to the project location, the components can be transported separately and assembled on site.

This design can provide greater flexibility for large-capacity projects.

For biogas plants, assembled tanks may be considered for different storage and processing applications depending on the project design.

Why Choose On-Site Tank Assembly?

Transportation is often an underestimated factor in large industrial projects.

A large prefabricated structure may require special transportation arrangements, suitable roads and additional handling equipment. In comparison, modular tank panels can be packed and transported more efficiently.

Once the components arrive at the project site, trained workers can assemble the tank according to the engineering drawings.

This approach is particularly useful for:

• Remote agricultural projects

• Large biogas plants

• Wastewater treatment facilities

• Industrial organic waste projects

• Projects requiring large storage capacity

  
  

The On-Site Installation Process

Professional installation is an important part of a bolted tank project.

The typical installation process includes site preparation, panel positioning, structural assembly, sealing, installation of accessories and final inspection.

The quality of sealing is particularly important. Proper sealing helps prevent leakage and ensures stable long-term operation.

Depending on the tank design, accessories may include inlet and outlet connections, manholes, valves, level indicators and other customized components.

Bolted Tanks and Biogas Plant Projects

A modern biogas plant may include anaerobic digesters, biogas storage, desulfurization equipment, gas flares, gas engines and other treatment equipment.

The storage capacity should be coordinated with the overall gas production and utilization system.

For example, a project with relatively high daily biogas production may require a larger storage solution to balance gas production and consumption.

Therefore, tank selection should not be considered separately from the overall biogas plant design.

How to Select a Suitable Tank?

Before contacting a biogas equipment manufacturer, project owners should prepare several basic parameters.

These may include required tank capacity, tank diameter and height, operating conditions, installation location, stored medium and local environmental conditions.

For international projects, transportation conditions and installation access should also be considered.

A professional supplier can then develop a suitable tank configuration according to the project requirements.

Combining Tanks With Biogas Desulfurization

Storage is only one part of a complete biogas solution.

In many projects, raw biogas must first pass through a biogas desulfurization system to reduce hydrogen sulfide before entering downstream gas utilization equipment.

The combination of biogas purification, storage and utilization equipment can create a more complete and reliable biogas treatment system.

Conclusion

Bolted tanks provide a flexible approach for large-capacity projects where transportation and installation are important considerations. On-site assembly allows modular components to be transported efficiently and installed according to the actual project conditions.

For developers planning a new biogas plant or upgrading an existing facility, early coordination between tank design, biogas treatment and overall plant layout can help reduce installation difficulties and improve project efficiency.
