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…
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.…
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…
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…
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.…
A couple of years ago on Chemical Engineering’s 120th anniversary, I looked back at the history of this publication and at that time, I wrote: “In September of 1902, the first issue of Electrochemical Industry was published to serve those…
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…
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…
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…
Conventional combustors that employ air-blast and pressure-swirl injection technologies are very sensitive to fuel properties, especially viscosity, limiting their ability to utilize certain classes of fuels and blends, including bio-based fuels. The new swirl-burst (SB) fuel-injector technology developed at Baylor…
