Industrial acids are essential raw materials for water treatment, metal processing, textiles, chemicals, laboratories, cleaning products, electroplating, pharmaceuticals, and many manufacturing lines. Chennai is a practical sourcing hub for acids because it supports drum, carboy, and tanker movement to industrial corridors across Tamil Nadu and South India.
Supreme Petro Chemicals supplies multiple industrial acids from Chennai. This guide focuses on sulphuric acid, nitric acid, and hydrochloric acid, three of the most commonly requested bulk acids.
Sulphuric Acid
Sulphuric acid has CAS number 7664-93-9. It is used in chemical synthesis, pH adjustment, metal treatment, battery-related applications, textile processing, fertiliser-related processes, and wastewater treatment. Buyers should specify concentration, grade, quantity, and packaging.
Nitric Acid
Nitric acid has CAS number 7697-37-2. It is a strong oxidising acid used in metal pickling, nitration chemistry, laboratory use, surface treatment, and chemical manufacturing. Because it is oxidising and corrosive, storage compatibility and handling controls are especially important.
Hydrochloric Acid
Hydrochloric acid, often called HCl, has CAS number 7647-01-0. It is used for pH correction, steel pickling, water treatment, cleaning, chemical synthesis, and regeneration of ion exchange systems. Commercial concentration and packaging must be specified clearly.
Applications by Industry
- Water treatment: pH adjustment, neutralisation, and process control.
- Metal processing: Pickling, surface cleaning, scale removal, and preparation before plating or coating.
- Textiles: pH control and processing support in selected dyeing and finishing operations.
- Pharmaceuticals and chemicals: Reaction chemistry, salt formation, and intermediate manufacturing.
- Laboratories: Reagent use where the correct grade and concentration are required.
Packaging and Supply Options
Acids may be supplied in carboys, drums, IBC tanks, or tanker loads depending on the product, concentration, quantity, and compatibility requirements. Packaging should match the acid type and concentration. Buyers should confirm whether their receiving site has safe unloading, spill containment, PPE, and compatible storage.
Documentation to Request
Ask for MSDS/SDS and, when needed, a Certificate of Analysis. The documentation should match the exact acid, concentration, and batch or lot supplied. For regulated or audited manufacturing, keep documentation linked to goods-receipt records.
Safety and Storage
All three acids are corrosive. Nitric acid is also a strong oxidiser. Store acids away from alkalis, incompatible metals, oxidisable materials, and product-specific incompatibilities listed in the SDS. Use acid-resistant PPE, face protection, ventilation, and compatible transfer equipment. Always follow site safety procedures for dilution and spill response.
FAQ
Can one supplier provide multiple acids?
Yes. A full-line chemical distributor can coordinate multiple acid requirements, but each acid must still be specified separately by concentration, grade, and packing.
Are acid tanker loads available?
Tanker supply depends on product, concentration, quantity, destination, and unloading facilities. Share your monthly requirement for confirmation.
How do I request a quote?
Send acid name, concentration, quantity, packaging, and delivery location. Contact SPC for sulphuric, nitric, hydrochloric, and other acid enquiries.
