HEMPA is an organophophoric acid, which exhibits excellent chelation, scale inhibition and corrosion inhibition. It is mainly used in oilfield, detergent / soap and metal treatment etc, especially useful in the water sytems with high level of dissolved iron and calcium. It is also compatible with methanol/water solution. When built together with other water treatment chemicals, it shows good synergistic effects.
HEMPA is usually used together with other organophosphoric acid, polycarboxylic acid and salt in different areas.
