Applications Of Chemical Equilibrium In Industry

PPT Chemical Equilibrium 化學平衡 PowerPoint Presentation, free download


In the field of chemistry, chemical equilibrium plays a significant role in various industrial applications. Chemical equilibrium is the state where the rate of forward and backward reactions is equal, and the concentration of the reactants and products remains constant. This article will discuss the different applications of chemical equilibrium in the industry.

Industrial Applications of Chemical Equilibrium

1. Ammonia Production

Ammonia is an essential component in the production of fertilizers, plastics, and explosives. The Haber process, which involves the reaction between nitrogen and hydrogen gases, is used to produce ammonia. The reaction takes place at high pressure and temperature, and chemical equilibrium is utilized to maximize the yield of ammonia.

2. Petroleum Refining

Petroleum refining involves the separation of crude oil into different components such as gasoline, diesel, and lubricants. Chemical equilibrium is used in the process of catalytic cracking, where high temperatures and pressure are applied to break down the longer hydrocarbon chains into smaller ones, resulting in the desired products.

3. Water Treatment

Chemical equilibrium is also used in water treatment to remove impurities such as heavy metals and bacteria. In the process of coagulation, a chemical such as aluminum sulfate is added to the water, and it reacts with the impurities to form flocs. The flocs are then removed through sedimentation, resulting in clean water.

4. Food Production

Chemical equilibrium is utilized in the production of various food products such as cheese and yogurt. The fermentation process involves the conversion of lactose into lactic acid by bacteria. The reaction reaches chemical equilibrium, resulting in the desired product.

5. Pharmaceuticals

Chemical equilibrium is applied in the production of drugs such as aspirin. The chemical reaction between salicylic acid and acetic anhydride produces aspirin. The reaction reaches chemical equilibrium, and the product is isolated through filtration.


In conclusion, chemical equilibrium plays a crucial role in various industrial applications. It is utilized to optimize the yield of products, remove impurities, and produce desired products. Understanding the principles of chemical equilibrium is essential in the field of chemistry and industrial processes.
