Natural Gas Processing and Liquefaction Simulation in Aspen HYSYS

Designing and optimizing natural gas facilities requires a solid grasp of thermodynamic principles and process simulation tools. This text-based course guides you through the fundamentals of modeling gas processing and liquefaction systems using Aspen HYSYS. You will transition from understanding basic chemical engineering concepts to confidently setting up, running, and analyzing complex gas plant simulations. By the end of this guide, you will gain the skills to evaluate process performance, select appropriate fluid packages, and design efficient liquefaction cycles. What you'll learn: - Understand foundational thermodynamic models and select the correct fluid packages for natural gas systems - Model core gas processing unit operations including separators, compressors, expanders, and heat exchangers - Simulate natural gas dehydration and sweetening processes to meet pipeline specifications - Design and analyze refrigeration loops and multi-stage liquefied natural gas (LNG) liquefaction cycles - Apply modern energy-efficiency and carbon-emission reduction concepts to process design - Troubleshoot common simulation convergence errors and interpret key performance metrics The course begins with essential terminology, property package selection, and basic flowsheeting interface navigation. You will then progress through step-by-step written tutorials covering dehydration, acid gas removal, NGL recovery, and LNG liquefaction modeling. This course is designed for beginner process engineers, chemical engineering students, and professionals new to Aspen HYSYS. No prior simulation experience is required, though a basic understanding of fluid mechanics and thermodynamics is helpful. Start reading today to build your practical process simulation skills.
