利用焦油气化技术将石油炼制过程中副产的液体残渣(苯酚焦油、双酚焦油、乙烯焦油等)在高温高压下生成以CO、H₂为有效成分的粗合成气,作为制氢的原料气或燃料。该技术一方面将这部分原设计需焚烧处理的残渣用于生产工艺气体,大大提升了其中碳含量的利用效率;另一方面利用煤气化技术内含的酸脱技术有效脱除了残渣中的硫元素(硫也转化为H₂S,进而变成产品硫磺),大幅降低了脱硫成本,具有一定的环保意义。该应用可实现石油炼制高硫液体残渣的高效清洁利用,进一步提高原油的综合利用效能,可为同类型的炼化一体化工厂生产流程优化和降本提效提供方向性参考。

The liquid residues (including phenol tar,bisphenol tar,ethylene tar,etc.) by-products in the petroleum refining process are processed via tar gasification technology at high temperature and high pressure to generate crude syngas with CO and H₂ as active ingredients,which is used as raw gas or fuel for hydrogen production.On the one hand,part of the residues that were originally designed to be incinerated are used to produce process gas,which greatly improves the utilization efficiency of carbon content.On the other hand,the acid removal technology contained in the tar gasification technology effectively removes sulfur in the residues,which greatly reduces the cost of desulfurization and presents certain environmental protection significance.Sulfur is also converted into H₂S,and then becomes sulfur product.This technology can realize the efficient and clean utilization of high-sulfur liquid residues in petroleum refining,further improve the comprehensive utilization efficiency of crude oil,and provide a directional reference for the optimization of production process,cost reduction and efficiency improvement of similar refining and chemical integrated plants.
