A reputable competitor with comprehensive simulation features. 3. Training and Certification Programs
Aspen HYSYS V7.3, released over a decade ago by Aspen Technology, was a significant upgrade at the time. Introduced as part of the aspenONE® V7.3 Engineering Software suite, this version included features that are still foundational today. A standout addition was the built-in Aspen Fired Heater model, which allowed refiners to study operating constraints, predict revamp benefits, and analyze crude selection for maximum profit. Another major innovation was the integration of the , enabling engineers to check a process's energy efficiency and report equivalent CO2 emissions directly from within HYSYS—a critical feature for modern sustainability goals.
