GDT Lining Systems have recently completed the construction of a Molasses Bladder

Molasses generates CO2 and H2S when stored. Molasses often enters the storage hot and cools of, emitting gas as it loses heat. If the gas is not removed from under the cover it will interfere with the roof drainage which may cause the gas flow under the cover to be blocked and large bubbles in the cover system to form. The solution is to provide:

• A large central float with a gas collection pipe system on either side and provide positive extraction of the gas by way or an in line industrial fan. Application of a small negative pressure under the cover has a big effect, pulling the cover down against the stored molasses and allowing water that is collected on top of the cover, from precipitation, to find its way to the perimeter drainage sump.
• Provide perimeter rather than central weights to the system. This allows the cover pumps to be located near the edge of the storage for accessibility.

What we Do

Mission Statement

GDT Lining has a mission to improve the industrial landscape by containing any harmful waste. We accept that waste is a biproduct of our industrial society. We aim to mitigate the downside to a level which is acceptable, by limiting the spread and effect of waste materials on everyday life.

“Molasses is a difficult substance to store and transport – hands on experience is an advantage.

Other applications involving the production of gas by stored liquids

Anaerobic Digestors produce gas. Covered storages are often used to collect the gas. Gas is piped from the storage to flares and boilers.

Aerated water storage. Air is often blown through stored water to condition or mix it. The air may be blown through a pipework system in the bottom of the storage and must be vented through the geosynthetic cover to atmosphere.
