Purity Decomposition to the Refinery Hydrogen Integration

This paper presents the application of problem decomposition to the retrofit of refinery hydrogen networks. In this regard, problem decomposition principles are developed to the hydrogen integration. In addition, a new algorithm is proposed. The algorithm is based upon problem decomposition principles originally introduced by Amidpour and Polley in 1997. The procedure proposed can maximize the amount ofhydrogen recovered across the site. This study is illustrated with an industrial case study. The stages of the work such as targeting, simulation etc. are performed in REFOPT1 software environment. The results show that this methodology can modify hydrogen networks more effective than the previous approaches.
