伴随着经济社会的发展,全球范围的原油重质化以及劣质化的进程在不断加速,各国开始增加了对轻质油产品的需要量。作为转化以及加工重质渣油的重要途径之一,延迟焦化日益显出来了自身的重要地位。在炼油企业中,延迟焦化装置是重质油加工系统中最为重要的装置之一。从最近若干年的发展来看,伴随着不断加重的原油重质化以及劣质化,延迟焦化的发展极其迅猛。文章讨论了眼下延迟焦化工艺的自身发展现状,评述了延迟焦化的最新技术进展状态,分析了在延迟焦化生产所存在的相关问题。在此基础上,文章提出了焦化装置在未来的发展趋向方面的相关建议。
Along with the economic and social development, the process of globalizing crude oil quality and inferior quality is accelerating. All countries have started to increase the demand for light-oil products. As one of the important ways to transform and process heavy residual oil, delayed coking becomes more and more important in its own right. Among refineries, delayed coking units are one of the most important units in heavy oil processing systems. Judging from recent developments in recent years, the development of delayed coking has been extremely rapid with the worsening of heavy crude oil and the deterioration of crude oil. This article discusses the current status of delayed coking technology itself, reviews the state of the art of delayed coking technology, and analyzes the related problems in delayed coking production. On this basis, the article puts forward some suggestions on the development trend of coking plant in the future.
