A Novel Mathematical Method for the Simultaneous Optimization of Hydrogen Network and Reactor

Abstract

In refinery, the hydrogen-consuming reactors have a great effect on the hydrogen network integration, their optimization should be considered simultaneously. This paper propose a new mathematical programming model for the optimization of the hydrogen network. The objective is to target the hydrogen-consuming reactor and hydrogen network with the optimal economic performance. In this model, the match between hydrogen source and hydrogen sink, sulfur content of the feed oil, hydrogen consumption and the operating conditions of the reactor are considered simultaneously. The latter includes the residence time, pressure, temperature and hydrogen to oil ratio. Based on this model, the overall optimization of the hydrogen network can be achieved easily, as well as the optimal hydrogen distribution network and the optimal operating conditions of the reactor. The hydrogen network of a refinery is optimized by the proposed method.
