Salt-Mist Resistant Defoamer for Oilfield Reinjection

Foam in oilfield reinjection water carries salts and corrosive substances, reducing injection efficiency by 30% and causing millions in annual pipeline losses. One oilfield reported 12 yearly repairs and 70% injection efficiency due to foam.

Chemi Tech's silicone-nano TiO2 composite defoamer features:

Salt-Mist Resistance: Nano TiO2 forms a passivation layer, passing 480-hour salt-mist tests (industry standard: 96 hours);

Thermal Stability: Active from -20°C to 120°C, suitable for downhole conditions;

Targeted Adsorption: Modified particles preferentially adsorb at foam interfaces, effective at 0.05% dosage.

Case Study: Offshore Oilfield Reinjection System

A Iraq platform (reinjection water: 12% salinity, 80°C) using Chemi Tech's defoamer (0.1% concentration) achieved:

72-Hour Foam Control: Manual interventions reduced by 60%;

Corrosion Suppression: Pipeline rusting rate decreased 60%, lifespan extended to 8 years;

Efficiency Boost: Injection pump efficiency restored to 95%, saving ￥3M/year.

This solution also resolves foam carryover in shale gas fracturing flowback fluid, reducing separator clogging risk by 50%.
