This Process Design Engineering course by PAYO’S Academy offers a complete roadmap for chemical engineers to understand and apply the principles of process design. The course begins with an introduction to chemical engineering concepts and career opportunities, followed by a detailed explanation of process design stages from conceptual design to startup. Key elements include process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and process basis documents, essential for efficient project execution. Students learn equipment sizing, including pumps, tanks, vessels, and heat exchangers, along with line sizing calculations and two-phase flow considerations. The course also covers control systems, including control valve selection and sizing, pressure safety valves (PSVs), and process utilities like steam, cooling water, and instrument air. Advanced topics include distillation column design, material and energy balances, and flow measurement techniques using differential pressure, ultrasonic, and magnetic meters. Throughout the course, real-world case studies and examples illustrate practical application of concepts. By the end, learners gain the skills to design, simulate, and optimize chemical processes, making them prepared for roles in EPC projects, process engineering, and chemical plant design.
