Mass Transfer
Mass Transfer is a fundamental process in chemical engineering where materials move from one place to another within systems, like how perfume spreads through a room or how sugar dissolves in coffee. Chemical engineers use this concept when designing equipment and processes that separate or combine different materials. It's essential for many industrial processes, such as water treatment, oil refining, or producing everyday products like medicines and foods. When you see this term in a resume, it indicates that the candidate understands how to control and optimize these movement processes in industrial settings.
