Large-scale production of chemicals through efficient processes.

Industrial chemistry produces chemicals on a very large scale, often in continuous processes that run for months between shutdowns. Plants use catalysts to speed reactions and raise selectivity, heat integration to recover energy, and recycle streams of unreacted feedstock to maximise yield. Key high-volume commodities include sulfuric acid, ammonia, ethylene, chlorine, sodium hydroxide and cement, and they supply almost every other sector. Economic efficiency depends on feedstock cost, energy use and waste treatment. Process design balances these constraints against profitability and safety.
Key ideas: Large-scale processes are chosen for yield, cost and safety. Key examples: Haber (ammonia), Contact (sulfuric acid), Ostwald (nitric acid), chlor-alkali, Solvay (sodium carbonate). Principles: Le Chatelier optimization of temperature, pressure and catalyst, recycling unreacted feed, heat integration, continuous operation and economies of scale. Sulfuric acid output is a measure of national industry.
Common mistakes and connections: Mistake: maximizing yield alone, when rate, equipment cost and energy dictate conditions (a compromise temperature). Batch versus continuous mode affects economics. Waste byproducts need handling. Links to equilibrium, catalysts and green chemistry.
Approximate annual world production of leading industrial chemicals, in million tonnes, which feed fertilisers, plastics, and almost every other chemical sector. The interactive lesson shows this as a live animation or chart.
Sulfuric acid is among the highest-tonnage chemicals made, with world production exceeding 200 million tonnes per year.
