Engineered for High-Stakes Applications

Combatting Dissolved Oxygen Pitting in High-Pressure Pipelines

In oilfield waterflooding and enhanced oil recovery (EOR), seawater and produced water are injected deep into geological formations to maintain reservoir pressure. Untreated water contains up to 8-10 ppm of dissolved oxygen, which aggressively attacks carbon steel tubulars and causes catastrophic pitting.

Our high-concentration Ammonium Bisulphite 70% and Oxygen Scavenger formulations react rapidly with dissolved O2:

For cold subsea environments (such as offshore North Sea or deep marine waterflooding), our Nickel Catalyzed and Cobalt Catalyzed formulations lower activation energy, accelerating reaction kinetics by up to 10-fold even in low-temperature waters.

Rapid Dechlorination & Membrane Protection

Residual free chlorine is lethal to aquatic life if discharged into water bodies, and it irreversibly degrades polyamide thin-film composite reverse osmosis (RO) membranes.

Our Ammonium Bisulphite solutions provide safe, complete, and instantaneous dechlorination:

Unlike sodium metabisulphite powders which require dusty manual bag dumping and dissolution equipment, our ready-to-dose liquid ABS solutions flow directly through automated chemical metering pumps with no clogging or dust exposure.

Reagent for Ammonia Caramel Colorings & Preservation

Ammonia Caramel (Class III, E150c) and Sulfite Ammonia Caramel (Class IV, E150d) are the most widely consumed food colorings in the world—found in soft drinks, beer, soy sauces, confectionery, and baked goods.

Uma Dye Chem produces Food Grade Ammonium Bisulphite under sanitary conditions with heavy metal levels strictly below international food safety limits (Arsenic < 1 ppm, Lead < 2 ppm). It also serves as an antioxidant and anti-browning agent during sugar refining and fruit/vegetable processing.

Bleach Neutralization & Chemical Synthesis

Following chlorine and hypochlorite bleaching of cotton and cellulosic textiles, residual chlorine must be completely eradicated before dyeing to prevent shade distortion and tensile strength loss. Ammonium Bisulphite acts as a dependable, non-damaging antichlor.

Additionally, in dyestuff and intermediate synthesis plants in Gujarat and Maharashtra, ABS is utilized as a mild reducing agent for reduction of nitro groups and sulfonation reactions.

Residual Chlorine Removal & Pulp Brightness Control

Chlorine-based bleaching stages in kraft and sulfite pulp mills leave residual oxidants in the pulp slurry and effluent that must be neutralized before further processing or discharge, as they otherwise degrade cellulose fiber strength and brightness stability.

Our Ammonium Bisulphite solutions act as a fast, reliable dechlorinating and anti-chlor agent in washing and bleach-plant effluent treatment, while also serving as a sulfonating reagent in certain sulfite pulping liquor preparations.

Reducing Agent for Dyeing & Chrome-Free Processing

Leather tanneries use mild sulfite-based reducing agents during dyeing, fat-liquoring, and chrome-reduction stages to stabilize color uptake and manage the oxidation state of process liquors.

Our Ammonium Bisulphite and Ammonium Sulphite Solution grades are supplied to tanning clusters for de-chroming baths and as a buffering reducing agent, helping mills maintain consistent leather tone and reduce effluent treatment load.

Corrosion Control in High-Pressure Steam Systems

Dissolved oxygen in boiler feed water accelerates pitting corrosion in economizers, boiler tubes, and condensate return lines, leading to costly unplanned shutdowns at thermal power plants and captive co-generation units.

Our catalyzed Oxygen Scavenger Formulation reacts rapidly with residual O2 even at low feed-water temperatures, protecting high-pressure steam-generating equipment and extending asset life with minimal chemical dosing.

Latex Stabilization & Anti-Coagulant Applications

Natural and synthetic latex processors require precise sulfite dosing to control premature coagulation, manage odor from residual preservatives, and stabilize latex compounds during storage and transport.

Our Ammonium Bisulphite solutions are used as a latex preservative additive and reducing agent during compounding, supporting consistent viscosity and shelf stability in rubber and latex manufacturing plants.
