Engineered for harsh industrial water chemistry, copper hydrometallurgy facilities, high-salinity reverse osmosis plants, and modern sanitization facilities throughout Chile.
Chile stands as a global powerhouse in mining, copper extraction, lithium brine concentration, and premium agricultural exports. In these intensive production environments, mineral scale, calcium encrustation, metal oxidation, and biofilm build-up present significant risks to thermal efficiency, pipe integrity, and production yield.
Sulfamic Acid (Amidosulfonic Acid, CAS No. 5329-14-6) is an odorless, non-volatile, stable crystalline dry acid that has become the preferred descaling and acid-cleaning compound in Chile. Unlike harsh liquid acids such as Hydrochloric (HCl) or Sulfuric Acid (H₂SO₄), Sulfamic Acid eliminates volatile hazardous fumes, lowers pitting corrosion rates on stainless steel and copper alloys by up to 80%, and offers safer dry handling across the steep transport routes from the Port of San Antonio and Port of Valparaíso to high-altitude Andean mining operations.
As a leading Chinese chemical manufacturer, Hebei Liuhe Chemicals Co., Ltd. delivers direct factory supply to Santiago, Antofagasta, Calama, Concepción, and Puerto Montt, providing tailored particle sizes, technical-grade formulations, and custom packaging designed to satisfy stringent Chilean environmental safety regulations.
From hyper-arid copper operations in the Atacama Desert to wine production facilities in the Central Valley, Sulfamic Acid delivers versatile, non-fuming chemical efficiency.
Used across Antofagasta and Atacama for clearing carbonate and sulfate scaling in solvent extraction (SX-EW) heat exchangers, slurry transport pipelines, cooling towers, and electrowinning cells without damaging delicate copper/titanium cathode plates.
Chile's booming coastal reverse osmosis plants rely on buffered Sulfamic Acid to clean mineral encrustations, iron fouling, and calcium salts from multi-stage flash distillers and polyamide membranes, preserving high throughput and water purity.
In the Maipo, Colchagua, and Maule valleys, Sulfamic Acid is standard in Clean-In-Place (CIP) systems to eliminate milkstone, beerstone, and wine calcium tartrate crystals from stainless steel fermentation vessels and pasteurization coils.
Pulp producers in Biobío and Arauco employ Sulfamic Acid as a chlorine dioxide bleaching stabilizer and superheated digester descaler, suppressing fiber degradation while neutralizing excessive calcium oxalate scale.
Reviewing physical-chemical benefits of Sulfamic Acid versus traditional liquid mineral acids in corrosive industrial environments.
| Evaluation Parameter | Sulfamic Acid (H₃NSO₃) | Hydrochloric Acid (HCl) | Sulfuric Acid (H₂SO₄) |
|---|---|---|---|
| Physical State & Handling | Solid dry crystal, safe bulk storage | Fuming volatile liquid, hazardous | Viscous liquid, high heat of dilution |
| Corrosion on Stainless Steel | Extremely Low (No pitting/chloride attack) | Severe stress-corrosion cracking risk | High corrosion at medium concentration |
| Descaling Calcium Carbonate | Fast reaction, forms water-soluble calcium sulfamate | Rapid, but produces corrosive fumes | Precipitates insoluble CaSO₄ scale |
| Transport Safety to Mining Heights | Class 8 Solid (UN 2967) - No liquid leak risk | High risk of liquid spills / vapor leaks | Extremely dangerous in transit accidents |
| Environmental & Effluent Footprint | Slowly biodegrades to ammonium bisulfate | Elevates harmful chloride ion levels | Causes heavy sulfate effluent spikes |
