BST-L50C liquid
BOILER STEAM TREATMENT – LIQUID CONCENTRATE
BST-L50-C is a specialized alkaline food approved amine blend for use in steam generating systems to neutralize carbon dioxide and complex oxygen in the steam and condensate. It is available in a liquid and in a solid form BST-S100-C.

Appearance: Clear Water White Liquid
Odour: Highly Ammoniacal
pH neat soln. at 25°C: 12.0 – 13.5
Specific Gravity at 25°C: 0.95 – 1.05
BST-L50-C is nominally dosed using the calculation 15/Total Alkalinity in the untreated condensate water. E.g. If untreated condensate has a total alkalinity of 7mg/l as CaCO3 the 15/7 = 2.14mg/l BST-L50-C dosage to feed water.
There is a specific test method for the determination of the residual BST-L50-C. This is a spectrophotometric method and is immediately available.
The specific active should be controlled at 0.2 – 0.5mg/l in the condensate water and so that
the pH of the condensate is >7.5 in most instances.
BST-L50-C can be stored for up to 24 months from the date of manufacture, in its original, sealed packaging, at room temperature in a dry area. This product can be safely stored in plastic type holding tanks designed to manage the specific gravity listed. BST-L50-C must be protected from heat, freezing and excessive aeration. Protective clothing such as gloves and goggles should be worn when handling BST-L50-C.
