工艺许可与催化剂

更高效的化工生产工艺技术

陶氏提供纯化环氧乙烷,环氧乙烷(EO)、乙二醇(EG)、氧代醇及纯对苯二甲酸(PTA)的生产工艺技术。一经许可的客户可享受我们的各类工程服务,包括工艺优化、工厂产能研究、工厂升级,以及由陶氏代表为您提供远程和现场技术支持。

环氧乙烷/乙二醇生产

陶氏的 METEOR™ 环氧乙烷/乙二醇技术旨在用于单独或组合生产纯环氧乙醇和乙二醇。METEOR™ 是最高效的环氧乙醇反应技术,该设计结合了工艺的简单性、安全性和出色的催化剂技术,改变了行业竞争格局。这有助于极大减少资本需求以及运营和固定成本,从而实现:

  • 主设备数量最多减少 20%
  • 占地面积最多减少 40%
  • 控制阀最多减少 50%
  • 流量元件最多减少 40%,安全阀最多减少 30%

陶氏的环氧乙醇工艺“METEOR™ HEXTEO 工艺”用于生产环氧乙醇衍生物,有助于客户将其反应器内99% 以上的 环氧乙醇产物回收为优质环氧乙醇。

氧代醇生产

陶氏的低压 LP OxoSM 技术是世界领先的通过烯烃生产醇的工艺。该工艺有助于实现更高的产出率,减少资本性支出、能耗和环境影响。LP Oxo SM 技术可与各种原料相容,以根据行业变化灵活生产多种产品。

截至目前,已有15个国家的55个项目采用了此项成熟技术,其代表了过去40多年的主流氧代醇生产工艺。LP OxoSM技术获得了 Kirkpatrick Chemical Engineering Award 奖项,氧代醇生产工艺中使用的 NORMAX™ 催化剂获得了R&D 100 Award 奖项。陶氏与 Johnson Matthey Davy Technologies Limited 正不断创新此项高度灵活的 LP OxoSM 技术。

LP OxoSM 技术生产的常见产品:

  • 用于涂料和增塑剂应用的 2-乙基己醇 (2EH) 产品
  • 用于涂料、胶粘剂、溶剂应用和衍生物生产的丁醇
  • 用于燃料的混合丁醇
  • 嵌段共聚物的辛醇(C8)
  • 含氧醛(C7-C9)
  • 较高分子量的增塑剂醇,如用于异壬醇 (INA) 的碳9,以及用于2-丙基庚醇(2-PH)的碳10
  • 洗涤剂用醇类(C11-C14)

陶氏还可提供生产碳7至碳9含氧酸的技术。

纯对苯二甲酸 (PTA) 生产

COMPRESS™ 纯对苯二甲酸 (PTA) 技术由陶氏和 Johnson Matthey Davy Technologies Limited 联合认证,是使用常规化学方法的简化工艺,在PTA生产中突破性地结合了压滤、溶剂回收和集成水循环工艺。该方法通常用作聚酯树脂的原料,有助于:

  • 投资成本减幅多达15%,工艺足迹减幅多达25%
  • 由于能耗和用水量减少,因此运营成本的降幅多达20%
  • 由于减少了大气和水流的排放,可最大程度减少环境影响。

该技术也可用于工厂改造。
