CNOOC Huizhou Petrochemical Company Limited (CHPCL) has selected Axens’ ParamaX® Technology Suite for its petrochemical complex expansion in Daya Bay, China.

 

The project aims at increasing CHPCL’s high-purity aromatics production capacity to 3 million tpy. The new aromatics complex will produce 1.5 million tpy of para-xylene in a single train.

 

Axens offered its second generation of the energy-efficient ParamaX Suite of technologies for the cost-effective production of para-xylene, benzene and mixed xylenes from aromatic-rich reformate and pyrolysis gasoline.

 

The ParamaX Suite includes the following solutions:

Arofining selective olefin removal technology, originally developed by Axens

Eluxyl 1.15 para-xylene purification technology, originally developed by Axens.

XyMaxSM-2, C8 aromatics isomerisation technology, originally developed by ExxonMobil Chemical Technology Licensing.

TransPlusSM-5, aromatics transalkylation technology, originally developed by ExxonMobil Chemical Technology Licensing.

 

Axens’ second generation of the energy-efficient ParamaX Suite provides good aromatics yields while reducing the plant’s energy consumption and enabling to manage investments for cost-advantaged aromatics production.

 

Since 2009, CHPCL has been operating an Axens’ ParamaX complex with a production rate exceeding 1.3 million tpy of pure aromatics.

 

Axens’ Process Licensing Global Business Unit Executive Vice-President Patrick Sarrazin said, “This brand-new, state-of-the-art aromatics complex will allow CHPCL to further improve its resilience and competitiveness while producing highly valuable aromatics products.”

 

Axens will also supply catalysts, adsorbents, equipment and a full-service offer from plant personnel training to successful plant start-up, followed by plant performance monitoring services.

 

The ParamaX Technology Suite is a combination of top-of-the-line processes aimed at the production of high-purity para-xylene and other aromatic molecules such as meta-xylene, ortho-xylene, benzene and toluene.

 

To date, Axens has licensed more than 30 ParamaX aromatics complexes and more than 400 process units aimed at aromatics production or transformation.
