CAUSTIC TANK OIL BLANKET
VANSEAL NG is hydrocarbon-based oil used to minimize evaporation of water or fumes at elevated temperatures. VANSEAL NG is used to decrease flash-off of volatile chemicals that would be expensive to replenish. Vanchem recommends using our VANSEAL NG on top of a CATALYST NG-Caustic stripping tank. Four to six inches is best practice.
