An approach to model the hydrodesulfurization (HDS) and hydrodemetallization (HDNi and HDV) of a heavy crude oil (21°API and 3.51wt% sulfur) was developed. By using data obtained from an experimental bench-scale reactor at different reaction conditions of LHSV (0.33–1.5h −1 ), temperature (380–420°C) and pressure (6.9MPa) keeping constant the hydrogen-to-oil ratio at 5000stdft 3 /bbl...
The present paper focuses on the study of process alternatives for heat integration of a heavy crude oil hydrotreatment plant. Experimental information obtained from a pilot scale, kinetics and reactor modeling tools, and a commercial process simulator were employed to develop mass and energy balances. Four study cases, which employ a combination of quenching and heat exchangers, were identified and...
