Henry's Law
Chemical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Henry's law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. It is essential for describing gas-liquid equilibrium at low concentrations.
Example in context
“We used Henry's law constant to predict the solubility of oxygen in water at 25°C for the bioreactor design.”
“Biyoreaktör tasarımı için 25°C'de sudaki oksijen çözünürlüğünü tahmin etmek için Henry sabitini kullandık.”
Where engineers use it
Henry's law is critical for gas absorption and stripping operations. Engineers use it to determine equilibrium solubility in wastewater treatment, carbonation, and bioreactor aeration.
Practice: can you use “Henry's Law” at work?
In a gas stripping operation, you need to find the minimum air flow rate to remove ammonia from water. Using Henry's law, calculate the equilibrium concentration of ammonia in air.
