创新焦化技术的可持续发展途径
的挑战
As the world pivots toward a net-zero future, the industry is faced with global challenges. Refiners are struggling to improve margins while transitioning to cleaner energy and adapting to a changing energy landscape.
One area where there is a clear transition is the demand for electric vehicles (EVs). 随着电动汽车的普及, 传统运输燃料将继续下降, while the requirement for synthetic graphite used in battery manufacturing is expected to grow.
另外, with more than 260 million tons of plastic waste is produced globally every year and only around 16% being recycled, 多余的要么焚烧, contributing to greenhouse gases or ends up in landfills and oceans.
为更可持续的炼油厂提供改造解决方案
伍德选择性收率延迟焦化技术(SYDEC)SM) is the leading method for residue upgrading for zero-fuel oil production. It provides refiners with the flexibility to utilise a variety of residues in their cokers to reduce waste and support energy transition objectives.
解决方案包括:
Due to the pandemic and the decrease in demand for transportation fuels, delayed coking units (DCU) are not operating at their design capacities. 为了应对这一挑战，Wood正在应用我们现有的SYDECSM technology to help clients repurpose existing cokers for a more sustainable future.
SYDECSM 循环(员工驱动创新)
Processing plastic waste supports future-proofing existing assets, enabling smooth transition of traditional refineries to support closing the loop on 塑料.
- Generation of high-value products while reducing the impact of 塑料 waste on the environment
- Robust economics – monetise low value waste, maximise asset utilisation and optimise tax benefits
- 提高产品质量(高辛烷值，石脑油等).)
- 增加年产量
