Arcanum Infrastructure, LLC and Axens NA Inc. today announce the successful ongoing operations and production of 1-Butene at Raven 1-Butene, LLC, which is an asset based on Axens AlphaButol® technology.

We are excited to announce the successful operation of the first asset under the Arcanum platform. We are very happy with the support and partnership of Axens as a licensor for the Raven Butene-1 project.

President Arcanum Infrastructure, LLC and Raven Butene-1, LLC
We initiated the startup activities late last year and reached full performance around mid-year. Starting a new process during normal times is challenging but COVID-19 made it even more complicated. The whole Raven team including Axens really pulled together well to insure a safe, efficient operation.
Nicholas Stewart
Raven Butene-1’s General Manager

The successful startup and operation of Raven Butene-1 represents yet another example of Axens AlphaButol® flexibility, and ability to produce best in-class sustainable petrochemical co-monomers. AlphaButol® is the highest reliable and cost-effective process for on purpose high purity 1-Butene production used as co-monomers in the production of various types of polyethylene plastic.

Today marks not only another achievement to the successful track record of AlphaButol®, but also its first startup on American soil. We congratulate the Raven Butene-1 team and Arcanum Infrastructure on this significant milestone and are pleased to renew Axens commitment throughout Raven project life cycle.

Axens’ AlphaButol® is the world leading technology for the production of on-purpose high purity 1-Butene through ethylene dimerization. It belongs to a family of technologies based on homogenous catalysis for which extensive research and development has been performed since the mid-60’s. Since the process operates in the liquid phase using a soluble catalyst system which avoids isomerization of 1-Butene into 2-Butene, there is no need for super-fractionation of the product stream.

There are now 40 AlphaButol® licensed units worldwide using homogeneous catalysis.

About Arcanum Infrastructure, LLC (Arcanum) and Raven Butene-1, LLC (Raven)

Arcanum develops, owns, and operates production and support infrastructure assets designed to provide long-term, reliable, and flexible solutions to downstream and petrochemical customers.

Arcanum is based in Houston, Texas and focuses primarily on opportunities in North America.

Through its subsidiary, Raven, Arcanum operates the 1-Butene production facility located in Baytown, Texas.

1-Butene is a linear alpha olefin (LAO) used in the manufacture of a variety of base chemical products, including as a co-monomer for production of polyethylene (LLDPE and HDPE). Most LAO products are produced by processes that result in a range of products, including 1-Butene. However, the Raven facility is designed for dedicated on-purpose 1-Butene production from the processing of ethylene (an available derivative of natural gas) to meet anticipated growth in the polyethylene and associated markets.
