延迟焦化工艺在重质/劣质原油加工过程中的地位和发展

Important role of delayed coking process in processing heavy low-quality crudes

指出21世纪中国炼油工业的重要发展方向之一就是要大力开展高硫重质(超重质)原油和劣质原油的加工,它不仅可以提高我国炼油工业的经济效益也是规避石油资源风险的一个重要战略措施。对于加工重质、劣质原油比例较高的国家(地区)如美国、加拿大、拉美国家和中国等,在炼油加工能力中焦化仍将占有较大的比例。分析了我国延迟焦化工艺发展中遇到的一些新情况、新问题,指出为了使焦化工艺能实现可持续发展,必需进一步提高焦化工艺的技术水平和竞争能力,在"大型化、高效化和清洁化"三个方向上继续努力。

One of the developments in China petroleum refining industry is to develop the processes for processing high-sulfur extra-heavy crudes.This will not only improve the economic benefits of petroleum refining industry but also is a strategic measure for minimizing the energy resource risks.In US,Canada,Latin America countries and China where the heavy and low-quality crudes are processed,delayed coking process is mostly employed.The new problems in the development of delayed coking process has been studied.It ...
