ATMP (Amino Trimethylene Phosphonic Acid)

ATMP or aminotris (methylenephosphonic acid) is a phosphonic acid/phosphonate. It is an excellent antiscalant and chelating agent to most metal ions like Ca, Ba, Mg, Fe and Pb, especially Calcium Carbonate (CaCO3). In the water system, it is difficult to hydrolyze and can distort the lattice. In a higher concentrated system, ATMP is also a good corrosion inhibitor. ATMP acid is used in industrial circulating cool water system of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit the corrosion of metal equipment and pipeline. ATMP acid can be used as a chelating agent in woven and dyeing industries and as a metal surface treatment agent.

DADMAC (Diallyldimethylammonium Chloride)

DADMAC (Diallyldimethylammonium Chloride) is often used as additive in daily chemicals to improve and modify product performances. As to petroleum chemicals, DADMAC can be used as flocculant and blocking agent.

HEDP (1 – Hydroxyethlyidene 1, 1 – Diphosphonic Acid)

HEDP (Hydroxyethylidene diphosphonic acid) is an organic phosphonic acid (phosphonate). The solid state of HEDP is crystal powder. It is also available as a colorless solution with varying concentrations according to requirements. HEDP forms stable chelating compounds with Cu, Fe, and Zn ions in water and shows excellent corrosion and scale inhibition capabilities in high-pH and temperature (? 482 °F) conditions. It is commonly used as an organic scale and corrosion inhibitor in various upstream, midstream, and downstream oil & gas applications.
