摘要/Abstract

摘要： 采用氢气夹点分析方法，得到炼油厂氢气流股基本分配方案，然后与计划优化模型联合进行优化，确定优化的氢气管网方案，并对方案的经济技术指标进行分析，评价方案的有效性。以国内某炼油厂为例，采用上述方案对氢气系统进行优化，结果表明：采用夹点分析技术可以使氢气纯度满足炼油厂加工工艺要求，结合计划优化模型可以有效地根据炼油厂生产状况优化氢气网络结构，达到节氢及优化炼油厂原油加工方案的目的；氢气系统优化后可节约氢气16.6%，并可加工劣质原油、降低原油采购成本，提高炼油厂经济效益。

Abstract: In this paper, the refinery hydrogen system was reallocated by means of a combination method of hydrogen pinch analysis technology and refinery operation planning optimization model to obtain optimization scheme of hydrogen system. Taking a domestic refinery as an example, the hydrogen reallocated scheme were calculated and analyzed by the pinch theory to meet the hydrogen purity required and to optimize the hydrogen network effectively by the combination method. It is shown by the results that this method can not only save the hydrogen 16.6% but also reduce the crude oil cost, while improves the ability of the refinery for processing lower quality freedstock.

Key words: hydrogen system, pinch technology, plan optimization model, linear programming
