Mesa's vapor and gas collection bladders are used to produce a predictable gas flow to either a combustion or recovery unit. First primarily used in gasoline distribution terminals, these holders are instrumental in providing a reliable, consistent flow of gas vapors to burners/recovery units. Vapor holders allow terminals to use a smaller burner/recovery unit by providing the capacity to store gasses during peak operating times. Vapor bladders and gas collection systems are commonly used in waste water treatment facilities to collect Methane vapors. These vapors are used to power an engine that assists in producing energy for the plant.

Mesa's vapor and gas collection bladders are suitable for 100% aromatic hydrocarbon, bio-gas, nitrogen and many other gases. They are generally manufactured using Mesa 6036.045FCAS. Other materials are available for specific corrosive chemical and high temperature applications.

The Bladder moves in a predicable pattern and does not rub against the tank walls or roof. A stabilizing weight is included to ensure the Bladder remains in a predictable position. The Bladder’s innovative urethane material containing closely woven nylon base fabric and vapor barrier ensure the reliable collection and storage of vapor emissions until processed by the Vapor Recovery system.
