据烃加工2021年6月9日报道，美国陶氏化学公司计划在其位于德克萨斯州自由港的世界规模生产基地建造一个综合二苯基甲烷二异氰酸酯（MDI）蒸馏和预聚物设施。这项投资支持了下游聚氨酯系统产品不断增长的需求，并提高了陶氏化学公司在建筑、消费和工业市场中具有吸引力的应用领域的领先地位，这些领域的增长将超过国内生产总值（GDP）。
新建的自由港MDI工厂将取代陶氏化学公司目前在德克萨斯州La Porte的北美产能，也将能够为陶氏化学业公司客户提供额外30%的产品。随着MDI新工厂的启动，陶氏化学公司将在2023年关闭其在La Porte的聚氨酯资产。
陶氏化学公司工业中间体和基础设施运营部门总裁Jane Palmieri表示：“此次MDI投资优化了我们现有的资产基础设施，增强了我们在全球聚氨酯领域的领导地位，进一步使我们能够支持下游系统客户的增长。”“在自由港基地的背面集成创造了一个具有成本竞争力的上游聚氨酯原材料供应，确保了一个可靠的供应位置，以支持我们在下游高价值聚氨酯市场的增长，并提供了一个更可持续的生产过程。”
位于自由港的新MDI工厂将减少陶氏化学公司的碳足迹和水的使用量：
• 通过利用自由港基地现有的热能，消除对火力发电的需求，
• 通过提高生产效率减少取水量和废水的排放，
• 取消运输原材料的需要。
陶氏化学公司广泛的聚氨酯系统特许经营升级关键聚氨酯组件，以生产刚性、半刚性和柔性泡沫，以及涂料、粘合剂、密封剂、弹性体和复合材料，应用范围从工业和基础设施解决方案，到消费者舒适的地板、家具、床上用品和鞋，汽车内饰解决方案，节能隔热材料。

Dow to build MDI distillation and prepolymers facility
Dow plans to build an integrated MDI distillation and prepolymers facility at its world-scale manufacturing site in Freeport, Texas. This investment supports increasing demand for downstream polyurethane systems products and advances Dow’s leading positions in attractive applications in construction, consumer, and industrial markets that are growing above GDP.
The new Freeport MDI facility will replace Dow’s current North America capacity in La Porte, Texas, and will also be capable of supplying an additional 30% of product to Dow’s customers. In coordination with the start-up of the new MDI facility, expected in 2023, Dow will shut down its polyurethane assets at the La Porte site.
“This MDI investment optimizes our existing asset infrastructure and enhances our global polyurethanes leadership position, further enabling us to support downstream systems customers’ growth,” said Jane Palmieri, president of Dow’s Industrial Intermediates & Infrastructure operating segment. “The back integration at the Freeport site creates a cost competitive supply of key upstream polyurethane raw materials, ensures a reliable supply position to support our growth in downstream high-value polyurethane markets and delivers a more sustainable production process.”
The new facility in Freeport will reduce Dow’s carbon footprint and water usage by:
•eliminating the need for the generation of thermal power by utilizing existing thermal energy from the Freeport site,
•reducing water intake and wastewater discharge (through production efficiencies), and
•eliminating the need for transport of raw materials.
Dow’s extensive Polyurethane Systems franchise upgrades key polyurethane components in order to produce rigid, semi-rigid and flexible foams, and coatings, adhesives, sealants, elastomers and composites for applications that range from industrial and infrastructure solutions, to consumer comfort solutions in flooring, furniture, bedding and footwear, to automotive solutions for vehicle interior, and energy-efficient insulation materials.
