这篇文章说得是啥?
In recent years,as the increasing of high sulfur crude oil and the lowering of quality of crude oil,our coking processing ability has promptly improved,and delayed coking technology is becoming gradually popular.Enterprises invest to construct large scale delayed coking projects.Native refinery experts expect that,our delayed coking technology will boost in the future five years.
Delayed coking is a crude oil deep processing technology that transforms residual oil into gas and light & medium distillate oil and coke through drastic thermal cracking.It is also a key approach that enterprises in and abroad promote yield coefficient of light oil and product refinery coke.It features in simple flow,high adaptive raw material,mature and reliable technology,low expense in investment and operation and etc.Delayed coking has become main method for residual oil transformation in oil refinery industry throughout the world.According to national statistical agency,in the recent 10 years,newly developed coking capacity is more than 22% of newly developed residual processing capacity in our country.Largest processing scale of single set of coking equipment in the world has reached 6,730,000 ton/year,and the largest processing scale of that in our country has reached 1,600,000 ton/year.Delayed coking technology has become the main method of processing high sulfur crude oil.
From the development history of world oil refinery industry,it is seen that,as the decreasing of consumption in heavy fuel oil and increasing of demand in light oil,crude oil deep processing is still the development trend in oil refinery industry.Delayed coking as one of the main methods for crude oil deep processing will definitely develop swiftly.Since late 1990s,residual catalytic cracking and hydrotreatment capacity have both developed swiftly; and meanwhile,processing capacity increasing of delayed coking equipment is always closely behind.

近年来,随着高硫原油增加和原油性质变差,我国焦化加工能力得到快速提升,延迟焦化技术日益流行,企业纷纷投资建设大型延迟焦化项目.国内炼油技术专家预测:未来5年,我国延迟焦化技术将迎来繁盛时期.
延迟焦化是一种将渣油经深度热裂化转化为气体和轻、中质馏分油及焦炭的原油深加工工艺,也是国内外众多炼化企业提高轻质油收率和生产石油焦的重要手段之一.该工艺具有流程简单、原料适应性强、技术成熟可靠、投资和操作费用较低等特点.延迟焦化已成各国炼油业渣油转化的重要手段.据国家统计局统计,近10年来我国新增的焦化能力占到新增渣油加工能力的22%以上,世界单套焦化装置最大加工规模发展到673万吨/年,我国最大加工规模也已经达到160吨/年,延迟焦化技术已成为各炼厂加工高硫原油的重要手段之一.
从世界炼油业的发展历程看,随着重质燃料油消费的减少,轻质油品需求的增加,原油深度加工仍是炼油业的发展方向,延迟焦化作为重油深度加工的主要手段之一无疑将获得迅速发展.虽然自上世纪90年代后期以来,渣油催化裂化和加氢处理能力增长迅速,但延迟焦化装置的处理能力增长一直紧随其后.
