巴斯夫丁二烯抽提技术

可靠性的价值

 

巴斯夫以NMP（N-甲基吡咯烷酮）为溶剂的丁二烯抽提技术是回收高纯丁二烯的先进技术。

巴斯夫丁二烯抽提技术提供：

 

  • 可靠性高
  • 稳定性
  • 灵活性
  • 投资成本低
  • 运营成本低
BASF Butadiene Extraction Technology based on NMP (N-methylpyrrolidone) as solvent defines the state-of-the-art technology for recovery of high purity butadiene.

 The Process - Features

  • 高度以创新作驱动
  • 无与伦比的运营
  • 无腐蚀的工艺

  • 减少排放

  • 定制的解决方案

     

无与伦比的运营
使用巴斯夫丁二烯抽提工艺的工厂连续4至8年的在线运行时间是同类工艺正常在线运行时间的两倍。
无腐蚀的工艺
巴斯夫基于NMP的丁二烯抽提工艺是无腐蚀性的。

为什么？

由于溶剂在抽提过程中不会与其他产品发生反应，因此巴斯夫丁二烯抽提过程造成的污染可以忽略不计。碳钢在整个过程中提供了足够的抗腐蚀能力。此外，NMP是所有丁二烯抽提过程中产生的微量聚合物的优良溶剂。这样可以保持设备清洁。



减少排放

与同类工艺相比，巴斯夫丁二烯抽提工艺产生的残渣和杂质要少得多。例如，焦油不会累积。处置成本相应降低。巴斯夫丁二烯抽提工艺产生的废水最少。

选择性加氢（如BASF SELOP®加氢）可被整合到工艺过程中，以便将废弃物C4转化为有价值的丁二烯、丁烯和/或丁烷。这提升了的丁二烯和抽余液的产量到100%或更多。

定制的解决方案
巴斯夫为各种操作条件和产品要求提供了丁二烯抽提工艺。它由单独的模块组成，提供最佳的定制解决方案

The Process - Yield and Purity

  • Unsurpassed reliability
  • Stability
  • Efficiency
10th furnace stack of the steam cracker at BASF TOTAL Petrochemicals LLC in Port Arthur, Texas. The site produces basic petrochemicals and operates one of the world’s largest flexible feed steam crackers and the world’s largest butadiene extraction facility.
The BASF Butadiene Extraction process exhibits remarkable flexibility:
Its low susceptibility to impurities makes the BASF Butadiene Extraction process capable of processing any industrial C4 feedstock mixture, including but not restricted to C4-cut from naphtha crackers. It operates economically, even with low butadiene content feedstocks.
A hallmark of the BASF Butadiene Extraction process is its efficiency:
Compared to competing technologies, solvent resistance to hydrolysis and thermal decomposition reduces solvent consumption by up to 90% or more.
High yield and high purity:

Simultaneously, the process provides a high yield (>98%) of particularly high purity (>99.7%) butadiene.

 

The butadiene specification can be customized for each application.

The Process - Services

Global network of expert service providers

Worldwide, approximately one-third of all plants operate on the basis of BASF Butadiene Extraction Technology. BASF maintains a global network of expert service providers for licensees of its Butadiene Extraction Technology.

BASF’s licensees benefit from the experience of its team of experts in operations, processing, materials and environmental issues. In addition, BASF cooperates with its partners, Air Liquide and Lummus, as well as other associated service providers and suppliers to the petrochemical industry.

Experts are always on hand in the event of an unexpected malfunction or operating problems.

After start-up service

As a reliable partner of its licensees, BASF provides ongoing support following start-up of the plant with:

·  Additional employee training on site

·  Regular visits to plants

·  Consultation on operational and technical aspects

·   Emergency service

BASF cooperates closely with licensees on ongoing process improvements.

Eco-efficiency Analysis 

Butadiene Extraction Technology

Eco-efficiency Analysis proves: 

BASF Butadiene Extraction Technology based on NMP is Efficient and Environmentally Friendly

A scientifically-based eco-efficiency analysis in cooperation with ETH Zurich (“Swiss Federal Institute of Technology Zurich”) testifies to the high efficiency of the BASF Butadiene Extraction Technology, its environmental compatibility and low cost.

The study adhered to a procedure certified by TUV, a German testing and certification service, which compared the BASF Technology to the ACN (acetonitrile) and DMF (dimethyl formamide) processes.
