CST has the most comprehensive line of roof and cover options for BioEnergy applications.
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 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.
An option for smaller diameter storage tanks, a knuckle roof is best suited for lighter pressure and vacuum applications with no load bearing requirements. Fabricated from stainless steel to provide excellent gas zone longevity.
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.
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.

Styles come and go, and sometimes reappear. Take hats, for example. What’s fashionable in the 60s went out in the 70s but may come back a few decades later. However, when it comes to municipal water facilities, yesterday’s model is gone for good, replaced by a more contemporary, sustainable design.
Even when the lead actor gets sick, the show must go on. Not only is that true in show business, but it’s also true with big entertainment venues. Keeping the lights on and the seats filled during an extended period of repairs is a testament to collaboration and intelligent design, and that’s the spirit behind […]
