چکیده

Hydrogen network management has economic appeal due to its importance in oil refineries. It become genuinely relevant the restrictions of sulfur content fuels, which need hydrogen be removed. Mathematical programming can used as a tool for optimizing networks, and efficient within refineries achieved through material balance units that make up network. In this work, an optimization model Mixed-Integer Linear Programming (MILP) Nonlinear (MINLP) networks was applied minimize operating costs. The developed GAMS, it validated using literature case study real from Brazilian Refinery. operation cost reduced by 10% 19.6% with MILP 9.7% 31.5% MINLP, example 1 2, respectively. Comparing results, both achieve significant savings model, is easier solve, proved networks. However, via although not guaranteeing optimal solution, resulted lower capital design optimized also detailed, other extra were imposed on problem.
