🧪 Ammonium Sulphate (NH₄)₂SO₄ – Source, Uses & Industry Applications
🌋 What is Ammonium Sulphate?
Ammonium Sulphate is a white crystalline salt, primarily used as a nitrogen-based fertilizer, but it also finds roles in industrial, pharmaceutical, and food processing sectors.
It contains 21% nitrogen and 24% sulfur, making it an excellent source of essential plant nutrients.
🌍 Sources of Ammonium Sulphate
🔹 1. By-Product from Industries
Caprolactam production (used in nylon manufacturing)
Coke oven gas cleaning in steel plants
Flue gas desulfurization (FGD) in power plants
India sources large quantities from petrochemical and steel industries in Gujarat, Maharashtra, and Chhattisgarh.
🔹 2. Synthetic Manufacturing
Reacting ammonia gas (NH₃) with sulfuric acid (H₂SO₄):
2NH₃ + H₂SO₄ → (NH₄)₂SO₄
Also produced using gypsum and ammonium carbonate or ammonium hydroxide.
🏭 Where It Is Used – Industry-wise Applications
Industry Use How It Is Used
🌾 Agriculture Nitrogen-Sulfur fertilizer (21-0-0 +24S) Applied directly to soil, blended with NPK
🧪 Chemicals Intermediate for other ammonium salts Raw material for chemical synthesis
🧼 Textile & Dyeing Dye fixative, pH control agent Added to dye baths for improving color bonding
🧬 Pharmaceuticals Protein purification (salting-out agent) Precipitates proteins in lab-scale processes
🧯 Flame Retardants Additive for reducing flammability Added to resins and coatings
🧁 Food Processing Acidity regulator, yeast nutrient (E517) Regulated use in baking and fermentation processes
⚗️ Water Treatment Coagulant and microbial support Improves floc formation and promotes bacteria growth in bio-systems
🐄 Animal Feed Nitrogen supplement Limited use in ruminant feed to enhance protein supply
📦 Grades of Ammonium Sulphate
Grade Application
Fertilizer Grade Field crops, horticulture
Technical Grade Industrial and chemical uses
Food/Pharma Grade Controlled, limited applications
Forms:
Crystalline
Granular (preferred for agriculture – less dust, easy to spread)
Liquid solution (for spraying or blending)
🚛 Packaging & Supply
25 kg / 50 kg HDPE bags with liners
Jumbo bags (1 MT) for bulk supply
Custom packaging & private labeling available
⚠️ Handling & Storage
Non-combustible, but decomposes at high temperatures to release ammonia gas
Store in dry, covered, ventilated areas
Avoid mixing with alkaline substances or strong oxidizers
