Study of various petroleum refining processes such as distillation, cracking (e.g., FCC, hydrocracking), reforming, and hydrotreating.
EHY2102 is an intermediate-level course focused on (formerly known as RefSYS). While standard HYSYS is excellent for gas processing and simple chemical plants, EHY2102 dives into the specific "Refining" extension, which allows engineers to handle complex crude oil assays, track hundreds of petroleum properties, and simulate rigorous reactor units like FCCs and Hydrocrackers.

In the modern petroleum refinery, the Hydrocracking Unit (HCU) stands as one of the most versatile and complex conversion processes. For students in EHY2102 – Aspen HYSYS Petroleum Refining, mastering the simulation of the hydrocracker reactor is critical. Unlike fluid catalytic cracking (FCC), which uses heat and catalyst without hydrogen, hydrocracking uses hydrogen under high pressure to convert heavy vacuum gas oil (VGO) or de-asphalted oil into lighter, high-quality products such as jet fuel, diesel, and naphtha.

For CDU/VDU: set the bottom product flow rate slightly lower than the actual feed rate minus all side draws. This creates a small liquid holdup (overflash) that stabilizes the bottom temperature. Core Course Modules & Unit Operations In the
