Covers for BioEnergy Storage

CST has the most comprehensive line of roof and cover options for BioEnergy applications.


Overview

Multiple Tank Cover Options

BioEnergy Storage Solutions include the industry's best cover options for digester applications. The gas zone of a digester is the most corrosive area and requires appropriate design.

Along with this corrosiveness, there are many other factors (environmental, mixer loads, pressure, vacuums, ancillary equipment loads, etc.) that need to be considered in cover selection. CST Storage can design and engineer the right solution from the multiple cover types in its portfolio.

Externally Supported Roof:

The most common roof design in the industry with a smooth internal roof surface and no rafters. Used when moderate to high pressure or vacuum design limits are anticipated. It is also preferred when there are heavy load conditions expected from mixers and/or other ancillary equipment is installed in the cover.

Aluminum Pressure Dome:

Geodesic dome design can be utilized in moderate pressure and vacuum designs and can accommodate light load conditions. All-aluminum design is lightweight, free-span and resists corrosion better than many other alloys.

GeoFrame Supported Membrane Cover:

Unique proprietary design incorporating a geodesic aluminum strut support frame that provides a clear-span, obstruction-free cover which removes the need for center post and strap designs to support the membrane. Can be used in single and dual membrane configurations for low-medium pressure applications. Photo courtesy of Revolution Energy Solutions.

Dual Membrane Covers:

Designed to operate in applications with low to moderate gas pressures where there is not a design requirement for a fixed steel or aluminum cover. Multiple layers and optional center support structures are utilized depending on design considerations.

Membrane Gas Holders

CST can provide membrane gas holder that are commonly used in conjunction with other storage vessels to store and regulate gas form the process and send it to the generating set or flare device.

Applications

Digesters

CST provides the widest range of cover options available that will meet pressure ranges from 2" of vacuum pressure to 24" of positive pressure and handle loads from prop mixers and other equipment.
