In oilfield water treatment, BHMTPMPA is usually used as corrosion inhibitor and scale inhibitor. Its working principle mainly includes the following aspects:
Corrosion inhibition: BHMTPMPA can be adsorbed on the metal surface to form a layer of protective film, which can isolate the metal from direct contact with corrosive media, thus playing the role of corrosion inhibition and prolonging the service life of equipment and pipelines.
Complexation: BHMTPMPA has good complexation properties, can form stable complexes with metal ions, reduce the concentration of metal ions in the water, reduce the corrosion of metal ions on pipes and equipment.
Scale inhibition: BHMTPMPA can react with hard water ions (such as calcium, magnesium, etc.) to form insoluble complexes or precipitates, thus preventing the generation of scale and reducing the clogging of pipes and equipment.
Dispersing effect: BHMTPMPA also has a certain dispersing effect, which can help to disperse and suspend the impurities in water, preventing them from being deposited on the surface of pipes and equipment, and keeping the system clean.
Overall, BHMTPMPA in oilfield water treatment through corrosion inhibition, complexation, scale inhibition and dispersion of a variety of roles, can effectively protect metal equipment and pipelines, reduce the impact of corrosion and scale, so as to maintain the good operating conditions of the water treatment system.
