chemicalprocess

A chemical process refers to a sequence of operations that converts raw materials into useful chemical products. It encompasses chemical reactions, phase changes, separations and purifications, as well as energy and material flows within a production system.

Processes typically begin with feed preparation and reaction or transformation in a reactor, followed by separation

Design involves understanding kinetics, thermodynamics, mass and energy balances, and the selection of equipment such as

Examples include synthesis of ammonia via the Haber process, polymerization of ethylene to polyethylene, fermentation-based production

Safety and environmental considerations include hazard assessment, emissions control, waste treatment, and adherence to regulatory frameworks

Documentation and optimization rely on process diagrams and data, with process flow diagrams (PFDs) and piping
