Energy Balance
Energy Balance is a fundamental concept in chemical production that refers to tracking and managing how energy flows through production processes. Think of it like a detailed energy budget that helps ensure factories run efficiently and safely. Chemical engineers use energy balances to figure out how much heating, cooling, or power is needed at each step of making products. This is similar to how an accountant tracks money coming in and going out, but instead of money, they're tracking energy. Understanding energy balance is crucial for designing and running chemical plants cost-effectively while meeting safety and environmental standards.
