Almost all phosphoric acid is produced via the wet-acid process (WAP), which requires relatively pure raw materials and produces large volumes of a potentially hazardous, special waste called phosphogypsum, which is highly regulated in terms of storage and disposal. A…
In a first-of-its-kind endeavor, a hydrogen-fluoride-based alkylation unit producing linear alkyl benzene (LAB) is being converted into a solid-bed alkylation unit that employs UOP’s (Des Plaines, Ill.; www.uop.com) Detal-Plus alkylation technology for LAB. LAB is used in the production of…
Concern with energy efficiency has increased the popularity of window glass coatings that control the amount of sunlight that passes through, as well as windows made of thin solar cells that can turn them into electricity generators. Now researchers from…

The complex demands of oil-and-gas production often require the development of customized chemical technologies, and CPI companies are rising to meet these challenges The oil-and-gas and chemical process industries (CPI) are interconnected in that the oil-and-gas sector provides many of…
The kilogram is the last of the SI units (International System of Units) still defined by a physical object, rather than defined in terms of universal fundamental constants of nature. However, this will change in November 2018, as a multi-year…
A flowmeter for biopharmaceutical processes The Flexmag 4050 C (photo) is said to be the first electromagnetic flowmeter with a biocompatible, disposable flow tube specifically developed for single-use biopharmaceutical applications, including filtration processes, chromatography or buffer and media preparation. Featuring…
New pump technologies offer better containment and reliability to keep product flowing safely and efficiently Because moving hazardous or high-value product through the process in a cost-effective manner is the name of the game in today’s chemical process industries (CPI),…
