Aspen Hysys: User Certification Exam Questions
This is the second major milestone. It assesses one's ability to handle complex applications, with a focus on the midstream sector (e.g., acid gas processing, gas dehydration, sulfur recovery) and upstream sectors (e.g., flow assurance with Pipe Segments and Aspen Hydraulics). It also tests knowledge of the Safety Analysis environment for designing pressure-relief devices.
