Cost Engineering with Previously Owned Process Equipment
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.…
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…
Focus: Packaging
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…
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…
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…
Upgrading organic wastewater into fuel feedstocks
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…
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…
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…
Modern Level-Measurement Technologies for CPI Applications
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.…
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…
