ACURO's Nitric Acid inhibitor opens up a wide range of possibilities for the use of acids in chemical cleaning, pickling and oil field use.
Nitric acid has long been avoided as a chemical cleaning acid because of its severe corrosivity and the inability to inhibit that corrosion. Nitric is the acid of choice in cleaning stainless steel, aluminium and titanium.
ACURO's Nitric Acid Inhibitor is required so that a completely stainless steel pumping and delivery system be used, and that no alloys of steel other than stainless could be present in the system to be cleaned.
CURO's Nitric Acid inhibito now makes it possible to remove acid soluble deposits from stainless and mixed alloy systems without the use of an expensive stainless steel pump unit. Nitric acid can be used to remove deposits previously requiring difficult water blasting or multiple stage cleaning procedures.
Examples of this are the removal of iron sulphides and iron polysulphides from refinery and pulp and paper systems, or the cleaning of heat exchangers in amine contactors and refineries.
Nitric acid has never been popular in oilfield acidizing. Its extreme corrosiveness and the inability to add a corrosion inhibition eliminated nitric acid from consideration. With the availability of ACURO's Inhibitor, Nitric acid can now be used as an efficient alternative for applications using strong oxidizing agents such as chlorine dioxide, sodium hypochlorite (bleach) and hydrogen peroxide.
Dilute nitric solutions can be used to clean up water injection wells which have become plugged with iron sulphide and iron polysulphides. Nitric acid solutions can be used to remove polymer blocks and plugging within subterranean geological formations. As with all acid corrosion inhibitors, pre-application testing is required to ensure the acid inhibitor is not adsorbed on the formation rock, which if it did occur would result in fluid returns with unspent and uninhibited acid.
