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,…
Consider the potential for stem seal leakage when selecting a valve Experienced process control engineers follow familiar, time-tested steps when presented with a new system to design and specify. Selecting a control valve for a process always requires the same…
Significant sustainability benefits can be gained through optimization in steam-cracking furnaces. The study detailed here shows the specific decarbonization strategies that can help improve energy efficiency and reduce emissions The chemical process industries (CPI) rely heavily on steam cracking to…
With hydrogen’s evolution into an alternative fuel requiring precise production and storage, selecting the right valves has never been more important Hydrogen shows great promise in the search for alternative fuels. Handling hydrogen safely and reliably, from generation to end…
Environmental imperatives drive the development of technologies for the chemical recycling of plastic waste, but significant hurdles – including economic viability, collection logistics and feedstock complexity – need to be addressed for chemical recycling to have a larger impact Plastic…
Industrial electrolysis involves passing a direct electric current through an electrolyte to elicit a range of chemical reactions. Electrolyzers are key pieces of technology for producing many important industrial chemicals. This one-page reference reviews the basic general operation of an…
The purchase price of an electric motor is generally thought to end up as a small fraction (2–3%) of the motor’s total lifetime cost, with the majority of costs resulting from the electricity used by the motor. This makes motor…
Any loss of containment for liquefied petroleum gas (LPG) can have potentially catastrophic results. This article details various LPG storage configurations with special focus on the design of mounded-bullet systems Liquefied petroleum gas (LPG) is a mixture of propane and…
The following titles are recently published books that may be relevant for professionals in the chemical process industries (CPI): Fundamentals and Practice in Statistical Thermodynamics. By Jianzhong Wu and John Prausnitz. Wiley and Sons Publishing, 2024, 768 pages, $149.95. Rare…
Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…
