The Abu Dhabi Polymers Co. Ltd (Borouge), a joint venture between Abu Dhabi National Oil Co. (ADNOC) and Borealis, has awarded the Axens a licensing contract to supply a methyl tert-butyl ether (MTBE) unit coupled with 1-Butene production unit and 1-Hexene unit for the Borouge 4 project in Ruwais-Abu Dhabi, UAE.

For over a decade, Axens has built a strong relationship with Borouge, involved in technologies, catalysts and services supply. It has supported Borouge through different projects, notably its on-purpose 1-Butene production units which were installed in Borouge-1 and Borouge-3 plants using the AlphaButolTM technology.

As part of the new Borouge 4 project, Axens will provide the following technologies:

  • A 124 000 tpy MTBE and a 50 000 tpy 1-Butene unit.
  • A 75 000 tpy unit for the production of high purity 1-Hexene through ethylene trimerisation (AlphaHexolTM).
  • Downstream of the new steam cracker, a methyl acetylene and propadiene (MAPD) hydrogenation unit, a C4 hydrogenation unit and a Pygas 2-stages hydrogenation unit.

The scope of Axens’ work includes the supply of process books, catalysts and adsorbents, as well as proprietary equipment, training and technical services.

Axens’ Process Licensing Global Business Unit Executive Vice-President Patrick Sarrazin said: “Today marks a significant step towards the expansion of Borouge’s facilities. We are delighted to be the partner of choice for this project and grateful for the trust put into Axens technology, in particular in AlphaHexolTM which will allow Borouge to benefit from Axens’ strong experience in homogeneous catalysis for the production of on-purpose 1-Hexene by ethylene trimerisation. This investment will support the continuous growth of UAE petrochemicals, and create a lot of value for the country.”

The Borouge 4 complex will include the world’s largest mixed-feed cracker on the same location as its three existing plants. The complex will consist of a number of production units. The primary products will be ethylene, propylene, butadiene, MTBE, 1-Butene, Pygas, 1-Hexene and benzene from the new mixed-feed cracker and its derivative units. The ethylene and propylene will be converted into polyethylene and polypropylene products.
