的挑战

随着世界转向净零排放的未来，该行业面临着全球性挑战. 炼油商正在努力提高利润率，同时向清洁能源转型，并适应不断变化的能源格局.

一个明显转变的领域是对电动汽车(ev)的需求。. With increasing EV adoption, conventional transportation fuel will continue to decline, 而用于电池制造的合成石墨的需求预计将会增长.

另外, 全球每年产生的塑料垃圾超过2.6亿吨，其中只有16%被回收利用, the excess is either incinerated, 产生温室气体或最终进入垃圾填埋场和海洋.

Retrofitting solutions for more sustainable refineries

Wood’s selective-yield delayed coking technology (SYDECSM)是零燃料油生产中领先的渣油升级方法. 它为炼油厂提供了灵活性，以利用焦化炉中的各种残留物来减少浪费并支持能源转型目标.

解决方案 include:

  • High return on investment and low CAPEX revamps
  • 延迟焦化中再生塑料/橡胶和再生热解油的处理
  • 废润滑油再精炼生产符合IMO标准的低硫燃料油(LSFO)
  • SDA revamps for heavy lube stocks production
  • 数字解决方案和技术，以优化单元操作和发现容易实现的收入改善

    • 由于大流行和运输燃料需求的减少, 延迟焦化装置(DCU)没有以其设计能力运行. To address this challenge, Wood is applying our existing SYDECSM 技术，以帮助客户重新利用现有的焦化炉更可持续的未来.

    SYDECSM 循环(employee driven innovation)

    Processing plastic waste supports future-proofing existing assets, 实现传统炼油厂的平稳过渡，以支持塑料的闭环.

    • 产生高价值的产品，同时减少塑料废物对环境的影响
    • 强劲的经济效益——将低价值浪费货币化，最大限度地利用资产，并优化税收优惠
    • Increased product quality (higher octane, naphtha, etc.)
    • Increased annual production
      • Extended length of coking cycle
      • Reduced tube fouling and improved heater run length
      • Reduced foaming in coke drums

    SYDECSM 伏特

    利用燃料级延迟焦化装置生产高价值电池级针状焦炭

    • Premium grade coke produced by delayed coking of aromatic tars
    • 合成石墨是制造电动汽车(EV)锂离子电池的关键部件。
    • High-value premium grade of needle coke production
    • Enabling fossil fuel redirection to support sustainable economy

    Fully integrated DCU + SDA
