This packaging film is water soluble EcoSol® is a PVOH (polyvinyl alcohol) film (photo) that dissolves in water in minutes. It can be made into bags, pouches and sachets of many different sizes to create an efficient delivery system for…
Advanced level measurement devices enhanced with intelligence solve CPI challenges Chemical processes often require handling media that is corrosive, flammable, explosive or toxic with wide ranges in temperature and pressure and characteristics that include steam, dust, foam, turbulence and condensation.…
This article made available to you by: Previously used process equipment can offer significant cost advantages in capital construction projects, but there are important questions to consider before pursuing pre-owned equipment Many misconceptions persist in the marketplace about secondhand equipment.…
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…
Steam is commonly used across the chemical process industries (CPI) for a variety of end uses, including process heating, mechanical drive, moderation of chemical reactions and fractionation of hydrocarbons. Heat exchangers, turbines, fractionating towers, stripping columns, and reaction vessels are…
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…
Eighty years ago, in 1944, Dr. Hans Müller from Winterthur, Switzerland filed a patent application for a device designed to process liquid substances at the Swiss Federal Institute of Intellectual Property in Bern. Liquids prone to fouling on heated surfaces,…
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…
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…
