Can we return polymers to their primal state of short hydrocarbon molecules? Chemical recycling does just that — but it needs the correct technologies for the mixing of the raw materials.

Chemical Recycling

Mixing Technology for Plastic Recycling

Solvolysis and pyrolysis are two established technologies for chemical recycling. Both of these technologies involve demanding tasks for the mixing technology. This article summarizes the practical approaches to address these challenges — from lab, through piloting and demonstration scale, before building a commercial reactor or plant system.

SIP

Revolutionary Oxygen Impulse Technology for Steel Production

thyssenkrupp At.Pro tec is well known for the development of the sequence impulse process (SIP). When used on cupola furnaces, it considerably increased their cost-effectiveness in the past. In over 10 years of development work with Schubert & Salzer as their partner, Dr. Rainer Klock and the team at At.Pro tec succeeded in getting the SIP technology to work on blast furnaces, too, with the help of sliding gate valves. This is a story of a researcher who is on his way to becoming a plant manufacturer.

Keppel Infrastructure, Exxonmobil to Explore Low-Carbon Ammonia Solutions

Under a MOU signed between Keppel Infrastructure and Exxonmobil Asia Pacific, both the firms will work together to explore low-carbon hydrogen and ammonia solutions in Singapore. The move has been carried out in the background of the Singapore Government’s launch of the National Hydrogen Strategy which expects hydrogen to meet up to half of Singapore’s power needs by 2050.
