Tank Blanketing (Blanket Gas Regulator Valve)
Tank Blanketing In a nutshell
A tank blanket gas regulator (BGR) controls the flow of a gas, typically nitrogen, into a vessel or line. The role of the valve is to maintain the pressure of the blanket by opening when blanket pressure drops below a set point and closing when it reaches the desired level.
Why?
Because by blanketing a product with an inert gas like nitrogen, you protect it from contamination with air. This is important with fine chemicals and in marine environments where ingress of air could also mean ingress of salt and moisture. Blanketing with an inert gas is also safer than having a vapour space filled with a volatile vapour. Additionally, when a tank with a blanket vents to atmosphere, it is venting that blanket, not the valuable/dangerous/odorous/volatile/noxious gas below the blanket.
Where?
Fine Chemical Manufacturers, Sewage Works, Fuel Storage Sites and anywhere where the product will be affected by ingress of atmospheric air or where the product cannot be vent to atmosphere.
