Description
1. Product Overview
Caustic Soda Flakes 99% is a high-purity sodium hydroxide (NaOH) solid alkali widely used in petroleum refining, chemical manufacturing, and industrial processing operations. Produced through advanced chlor-alkali electrolysis processes, it delivers consistent alkalinity for neutralization, purification, and chemical synthesis applications.
Its primary roles in alkali refining and gas sweetening make it essential for removing acidic contaminants such as hydrogen sulfide (H₂S), carbon dioxide (CO₂), and organic acids from hydrocarbon streams. With its strong reactivity, high purity, and efficient solubility, Caustic Soda Flakes 99% remains a strategic raw material for refineries and chemical plants seeking reliable process performance and cost-effective contaminant removal.
