خلاصه مقاله:
One of the most critical issues in production of clean fuels is to manage the impact of the new environmental requirements on the hydrogen consumption in the refineries. Market requirements and environmental laws increase the dependency on hydrogen in oil refineries. Hydrogenmanagement is based maximizes the amount of hydrogen recovered across a site. The hydrogenrecovery from refinery off-gases reduces the requirement of hydrogen production. Differentmodels for purifiers units have been developed based on process parameters. In this paper, target for the minimum flow rate of fresh hydrogen required by the refinery using the models presented for the membrane and using off-gases. Equations obtained from Superstructure method are solved with nonlinear programming (NLP) of the General Algebraic modeling system (GAMS). Theresults of optimization showed the 30% reduction of operating cost in refinery hydrogen network.
