Facts At Your Fingertips: Steam Trap Operation
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…
Upcycling gypsum to sulfuric acid in a zero-liquid-discharge demonstration plant
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.…
Successful pilot study of wastewater reuse technology at commercial site
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…
Catalyst developed for conversion of CH4 to methanol
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…
Methods for Conceptual Capital-Cost Estimation
Conceptual capital-cost estimates are important for assessing the economic viability of proposed projects, but their usefulness depends on understanding how to appropriately apply the estimates Capital cost estimates are a crucial step in order to make prudent decisions regarding any…
New injector technology fundamentally improves combustion flexibility
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…
Chem Chronicles: A Look Back on 80 years of Thin-Film Evaporation
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,…
Conducting Hazard Reviews: A Practical Guide to Implementing Impactful Process Hazard Analyses
The insights reported here will help guide and encourage engineers in facilitating high-quality and effective hazard analyses in their facilities Undertaking and completing a well-planned hazard review might just be the best thing you ever do on a single day…
A more economical process for bio-succinic acid piloted
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…
Tower Doctor: The Case of the Lying Gamma Scan
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…
