Filtration: Removing solids from liquids using a mesh (e.g., brewing coffee). Evaporation: Removing a solvent to concentrate a solution. Heat Exchangers: Cooling down a hot chemical stream

In the field of chemical and process engineering, the physical and chemical changes occurring in a manufacturing plant are broken down into fundamental steps known as . This concept, first introduced by Arthur D. Little in 1915, revolutionized engineering education and practice. It posits that regardless of the specific product being manufactured—whether it is sulfuric acid, gasoline, soap, or penicillin—the individual physical steps involved are essentially the same.

While there are hundreds of specific operations, they generally fall into five functional categories:
