Chemical Engineering Process Calculations: Material and Energy Balances

Every chemical plant, from petrochemical refineries to pharmaceutical labs, relies on precise process calculations to run safely and efficiently. If you want to design, analyze, or optimize chemical processes, mastering material and energy balances is your essential first step. This course guides you through the fundamental principles of chemical engineering calculations. You will learn how to set up and solve steady-state and transient balance equations, handle recycle and bypass streams, and analyze combustion processes using systematic, step-by-step methodologies. What you'll learn: - Understand the core terminology of chemical process systems, including system boundaries, state variables, and units of measurement. - Formulate and solve material balances for systems with and without chemical reactions, including recycle, bypass, and purge streams. - Apply energy balance principles to open and closed systems, accounting for sensible heat, latent heat, and reaction enthalpies. - Perform combustion calculations, analyzing flue gas composition, theoretical air requirements, and excess air. - Develop systematic problem-solving strategies to break down complex, multi-unit chemical processes into solvable mathematical models. - Explore modern process simulation concepts and how manual calculations form the foundation of computerized process design. You will start with foundational definitions and unit conversions before moving on to single-unit material balances. From there, you will progress to multi-unit systems, reactive processes, energy balances, and real-world combustion scenarios through detailed written explanations and guided practice problems. This course is designed for aspiring chemical engineers, students preparing for academic coursework, and professionals seeking a clear refresher on core process calculations. No advanced chemical engineering background is required, though a basic understanding of chemistry and algebra is helpful.
