Unveiling the Value Chain of Ascend Products

At the Chocolate Bayou production facility, we convert ammonia and propylene into acrylonitrile. Most of this acrylonitrile is transported to the Decatur production facility for further processing, while the remainder is sold to the market, including general-grade and high-purity acrylonitrile. This year, our brand-new purification equipment was installed and commissioned, commencing the production of high-purity acrylonitrile.

Most of our acrylonitrile is used for producing hexamethylenediamine and polyamides, and it is also a key raw material for customers manufacturing other engineering materials, such as ABS (acrylonitrile-butadiene-styrene copolymer), SAN (styrene-acrylonitrile copolymer), as well as acrylic fibers and textiles. High-purity acrylonitrile can be applied in aerospace-grade fibers, nitrile gloves, water treatment, and other fields.

In the production process of acrylonitrile, the by-product hydrogen cyanide (HCN) is also collected and used in subsequent processes to produce specialty chemicals.

It is worth mentioning that the Chocolate Bayou production site has reached 1.5 million safe working hours. This reflects Ausden's commitment to a "zero-accident promise."

Acrylonitrile is transported from the Chocolate Bayou production site to the Decatur production site. At this world's largest electrochemical synthesis production site, we use the electrolysis dimerization process (EHD) to produce adiponitrile. Most of this adiponitrile is transported to the Pensacola production site, while the remaining portion continues to the next processing step at the Decatur production site.

Adiponitrile is a key raw material for the production of hexamethylenediamine.

Hexamethylenediamine is a transparent or light yellow liquid that is highly sensitive to temperature, water, and air. It is highly corrosive and toxic, requiring stringent conditions for storage and transportation.

Recently, we have commissioned newly constructed onshore storage tanks in Europe, enabling us to heat, load, and transport larger volumes of cargo and provide local customers with more flexible delivery options.

Hexamethylenediamine is a key raw material for the production of polyamide 66 (Nylon 66). From fashionable clothing, high-quality carpets, smart electronic consumer products, finely structured automotive parts to life-critical airbags, Nylon 66 resins and engineering materials quietly illuminate everyone's life.
