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.
While Aspen Technology offers numerous courses, is widely recognized in training catalogs as an intermediate-to-advanced course focusing on: EHY2102 Aspen HYSYS Petroleum Refining...Unit O...
HYSYS default reactors often predict excessive coke formation. Unit O teaches how to disable coke kinetics unless you have a full kinetic package. For CDU/VDU: set the bottom product flow rate
Unit operations are the building blocks of any petroleum refinery. These operations involve the separation, conversion, and treatment of various petroleum fractions to produce a range of products, including fuels, lubricants, and petrochemicals. Common unit operations in petroleum refining include: Unit O teaches how to disable coke kinetics
A mid-continent refinery experiences high pressure drop in its diesel HDS reactor. The current HYSYS model shows sulfur at 50 ppm, but lab data indicates 150 ppm.
