Optimize sulfur recovery: Sub-dewpoint sulfur recovery with interstage membrane
The author’s company’s new sub-dewpoint sulfur recovery with interstage membrane (SSRIM) technology is a breakthrough for the sulfur recovery industry, as it is the first technology capable of achieving an overall recovery efficiency of > 99.9% without requiring a tail gas treating unit. This article discusses the basic SSRIM configuration and its advantages when compared to a traditional Claus/TGT configuration.
Lummus successfully starts up PFAS demo unit to destroy "forever chemicals"
Lummus Technology has started up its per- and polyfluoroalkyl substances (PFAS) destruction demonstration unit. The at-scale, commercial-ready system uses a combination of advanced technology to destroy PFAS, also known as "forever chemicals."

Refractory lining reliability challenges in hydrogen-fueled process fired heaters
This article provides an overview of the potential impact of H2-rich fuel firing on refractory integrity and suggests safeguards to mitigate challenges. While this article discusses refractory issues in process fired heaters, the information presented can be broadly applicable to fired equipment where a flame is present.
Methods for increasing the heat transfer rate on steam condensation surfaces
Traditional systems rely on filmwise condensation for heat transfer; however, for large energy consumers, dropwise condensation will help improve heat transfer efficiency and reduce steam consumption and carbon footprint. This can be achieved through water treatment technologies—specifically the dropwise condensation technology—that help facilities increase productivity and reliability while reducing energy consumption.
Scaling pyrolysis: A critical step toward plastic circularity
Pyrolysis has potential to process hard-to-recycle plastics and expand the scope of recycling, but scaling up pyrolysis to meet global demand remains a significant challenge. From technical optimization to creating market confidence, addressing these barriers is essential if pyrolysis is to reduce plastic pollution and advance circularity.
