The residence time of the hydrogen consuming reactor affects its hydrogen consumption and the hydrogen network integration. Based on the integration of the hydrogen network, the quantitative relationship between the hydrogen consumption and the residence time is derived. The hydrogen utility adjustment versus residence time diagram is constructed to identify the variation trend line. Based on this, the minimum hydrogen utility adjustment and the location of pinch can be easily identified for any given residence time, and the sulfur content of the feed oil can be analyzed and optimized simultaneously. The hydrogen network of a refinery is analyzed, and the optimal residence time of the vacuum gas oil reactor is identified to be 0.813 h.
