Hydrogen is a vital substance for refineries in order to respond to increasing demand for clean and standard transportation fuels. Intensifying environmental regularities has reduced demand for heavy fuel in the world and it is necessary to convert such heavy fuels to cleaner and lighter fuels. To do this, a huge amount of hydrogen is needed, also hydroprocessing of refining products is known valuable and economical for increasing the quality and quantity of products makes Hydrogen Management in all refineries a matter of importance. The goal of this study is optimization of Imam Khomeini refinery hydrogen network. In this research at first, we have a review on previous record of hydrogen management in the refineries of the world. Then we proceed to the modeling and optimization of hydrogen Networks of Shazand refinery. Hydrogen network is presented in this research has high accuracy than other previous modeling because of new parameter definition in new model. After model execution, with change operation parameters at hydrogen network, one of the best result is no need for production hydrogen unit at phase one of Shazand refinery. Therefore based on economical estimation, cost and energy saving will be more than 2000 billion Rials at every year. Undoubted run this research at last year is one of the greatest achievement in oil refinery industry of Iran.
