The Latest and Greatest: John Crane CFD Polymer Melt Filtration Systems Increase Polycarbonate Production

Polycarbonates are thermoplastic polymers containing carbonate groups in their chemical structures. They are strong, tough materials, and some grades are optically transparent. In addition, they are easily worked, molded and thermoformed, and because of these properties, polycarbonates can be used in many applications. 

Polycarbonates are becoming increasingly important and popular as an environmentally friendly (recyclable) polymer. The global demand for polycarbonates was estimated at 4.6 million tonnes in 2019, and it is forecasted to increase to 5.5 million tonnes by 2024. This growth in demand is creating opportunities for technologies that enable increases in production capacity.

Message from the Chair: Driving the Filtration Industry Forward with Knowledge Sharing

Jeni Wong, ChairGuest blog from Jeni Wong, Chair of AFS. Jeni assumed the role of Chair last month and will serve in this position until September 2022. She has been an active AFS member since 2014, serving as Co-Chair of the 2017 Spring Conference and as a Board member since 2018. She also is active in ASHRAE, serving on the Technical Committee (TC 2.4) as the Membership Chair since 2017 and Voting Member since 2019.

As I move into the Chair role for AFS, I cannot help but reflect on how much has changed since I first joined in 2014. At that time, I was new to the filtration industry and looking to bolster my knowledge base in every way possible. I had met Rahul Bharadwaj (former Chair of AFS and current Senior Applications Engineering Manager at Lydall) and, though we both participate in other industry organizations and committees, he could not stop singing the praises of one in particular – AFS. His excitement for the important work that was being done was contagious, and I quickly became more and more involved myself. I realized that AFS was different because of the exceptional dedication of volunteers to not only furthering their own professional interests but also to truly building a better industry together.

A Message from the Chair: The Year in Review

As I conclude my year as Chair of the American Filtration Society, I’d like to take the opportunity to commend our organization and our many volunteers, sponsors and staff who continued to support and promote the missions of AFS in the past year.

When I assumed the role of Chair one year ago, we were six months into the COVID-19 pandemic with little understanding of how the virus would expand and persist. In February of this year, we entered a second year of the pandemic, and continued to explore new ways to engage with our members and distribute technical knowledge and filtration education. In a time when filtration couldn’t be more important, we bolstered our commitment to providing the resources necessary to maintain the flow of information, the building of professional relationships and the mentoring of tomorrow’s filtration leaders.

The State of Filtration in the Race to Zero Emissions and in the Wake of COVID

Brian Lane headshotAFS FiltCon 2021 included a plenary presentation from Brian Lane, expert filtration industry consultant and retired Vice President of Engineering, Technology and Innovation at Parker Hannifin. His presentation, “How Global Mega Trends, Particularly the 'Race to Zero Emissions' and COVID, are Impacting the Filtration Industry,” provided valuable insight into the state of the filtration industry, especially in light of the events of 2020.

Brian began by referencing the 2017 AFS Point of View Publication, written by former AFS Chair Tom Ramsey. Brian highlighted six global mega trends that formed the basis for chapter two of the report, emphasizing that after four years, all are still vigorous drivers of change in the filtration and separations industry: Population Growth and Social Change, Disruptive Digital Technology Changes, Rapid Urbanization on a Global Scale, Climate Change and Natural Scarcity, Transformative Healthcare Advances, and Reduce, Reuse and the Race to Zero Emissions/Discharge. In fact, the events of 2020 even accelerated the pace of change for several of them, most notably in the social change, healthcare and emissions areas.
