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。

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.

The butadiene condenser structure in the olefins complex in Port Arthur, Texas. The complex is a world-scale single train butadiene extraction facility and indirect alkylation unit. Butadiene is used in the production of rubber and plastic products. End products include tires, house paints, adhesives, masonry and carpet underlay.

Many years of experience

BASF Butadiene Extraction process is operational since 1968, in the meanwhile it has logged around 1000 operational years. Since 1990s BASF has licensed its Butadiene Extraction Technology to more customers than any other licensor. In total, 70 licenses have been granted.

Reliable partner network

Since 1990, BASF partners in butadiene extraction. Lummus Technology and Air Liquide have been providing their extensive engineering services, plant construction expertise and process technology.

Their services include initial studies, basic engineering and turnkey plants.

Eco-efficiency Analysis

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.
