Evaporation loss from Fixed Roof Tanks
Hydrocarbon/organic emissions from fixed roof storage tanks waste valuable product and pollute the environment, while posing a health hazard/ risk to people.
A typical uncovered tank
A typical uncovered tank of diameter 120 ft (36.6 m) results in the loss of around $300,000 of product annually. This equates to 1.7 million pounds (770 ton or 6400 barrels) of hydrocarbon released into the atmosphere as pollution.
EVAPOSTOP discs – the most effective solution
EVAPOSTOP discs can be installed in your tanks with minimal effort thus saving you money and downtime, and reducing the pollution to the environment. The EVAPOSTOP discs can have a short payback period and will continue to return profits for many years after their installation. EVAPOSTOP disc are completaly maintenance free and can be reused in other tanks (by adding or reducing the number of disc) when the marketing requires a change in tank service.
The Choice
EVAPOSTOP discs cover up to 99.6% of the liquid surface and reduce tank emissions by 90% or more. The discs have a wide range of benelits over conventional solutions:- they are extremely easy to install, have minimal downtime, and are non-corrosive, non-static and flexible in use. Additionally, the discs do not cause incendive sparks, which are commonly associated with aluminium internal floating roofs and may lead to internal explosions. They also greatly reduce the fire case in tanks.
