Irish-based multinational chemical company Linde and Shell have signed an agreement on ethane-oxidative dehydrogenation (E-ODH) technology for the production of ethylene.

Shell said that the catalytic process is an alternative to the process of ethane steam cracking.

It offers the potential of acetic acid co-production, as well as a significant reduction in the overall carbon footprint via power input electrification.

Linde and Shell have been developing E-ODH technology independently for many years.

Linde Engineering Global Sales & Technology senior vice-president John van der Velden said: “With the EDHOX process, we have not only developed a cost-efficient alternative but are also providing the petrochemical industry with a low-emission process.

“For decades, we have been actively developing technologies for more sustainability in this industry, from efficiency improvements to carbon management and new process routes. We are convinced that Linde’s EDHOX technology position will be strengthened by Shell’s intellectual property and know-how in this area.”

Under the new partnership, both companies will combine their ‘patent positions, expert know-how and common commitment’ for a lower emissions future.

The agreement will enable accelerated deployment of this novel technology across the wider chemicals sector, with Linde marketing to customers under the name EDHOX.

Shell’s global chemicals business executive vice-president Thomas Casparie said: “Base chemicals are transformed into a range of finished products that help society live, work and respond to climate change.

“We look forward to our Shell in-house innovation going on to contribute to the collective reduction of carbon emissions from the manufacture of chemicals. It’s been great to work with Linde on this ambitious and creative combination of technology.”

In April, Linde signed a contract to develop an air separation unit (ASU) for Indian Oil (IOCL) refinery at Paradip in Orissa, India.
