A pilot project evaluating the Electro-Ceramic Desalination (ECD) technology developed by Membrion Inc. (Seattle, Wash.; www.membrion.com) successfully recovered clean water from the reject water of a reverse osmosis (RO) desalination process at a commercial manufacturing site. Membrion’s technology uses ceramic…

A new demonstration plant is upcycling gypsum (calcium sulfate) — a material that is typically challenging to dispose of — at a metal-refining site using a process that combines salt-splitting electrolysis, caustic direct-air capture (DAC) and mineralization. Travertine Technologies, Inc.…
Plant Watch Evonik breaks ground on specialty-amine production plant in Nanjing November 11, 2024 — Evonik Industries AG (Essen, Germany; www.evonik.com) has broken ground on its plant expansion for specialty amines in Nanjing, China. The Nanjing plant specializes in producing…
The demand for “green” methanol as a low-carbon fuel is rising, making it a valuable commodity, as well as a promising avenue for waste-carbon utilization, especially since it can be readily produced from “stranded” carbon sources, such as flare gas.…
Although wastewater streams with high organic content — such as those from breweries and dairy facilities — can be difficult to treat and expensive to dispose of, there is potential to valorize their carbon content with the right process. Based…
Bio-based succinic acid has been explored as a renewable building-block for a host of chemicals and polymers, but its production process remains costly due largely to the complicated purification process that generates a large waste stream. Now, researchers at the…
Scientists at the Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) and collaborating institutions have engineered a highly selective catalyst that can convert methane into methanol in a one-step reaction. The system could help make better use of “stranded” natural gas…
Sustainable SMR In the pursuit of lowering greenhouse gas emissions, hydrogen has gained much attention as a potentially “clean” energy source. Typically, hydrogen is produced by steam methane reforming (SMR), a process which itself produces greenhouse gases. Efforts to lower…
Henry Kister shares lessons learned from troubleshooting distillation towers This conversation started in a course I was presenting in Sydney, Australia. I was about 15 minutes into my presentation when a delegate from a major petroleum refinery stopped me. “How…
