A single large-scale refinery simulation with a thermo package like Peng-Robinson can easily consume 18-22GB of RAM. Adding a dynamic pressure relief scenario pushes that to 30GB+. Part 4: High-Performance Computing (HPC) & Optimization If you run rate-based distillation , column hydraulics , or parallel batch simulation , you need enterprise hardware.
