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…
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…
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 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…
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…
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…
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…
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…
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…
