Paving the way for emissions-free renewable fuels
UOP, LLC, a Honeywell company (Des Plaines, Ill.; www.uop.com) and Wood plc (Aberdeen, Scotland; www.woodplc.com) are now licensing a combined technology suite that brings together UOP’s Ecofining renewable-fuels process with Wood’s Terrace Wall hydrogen-reforming furnace, with the aim of substantially…
Technology Profile: Production of Vinyl Acetate
Vinyl acetate (also known as vinyl acetate monomer; VAM) is important in the manufacture of many polymers and resins. The greatest demand for vinyl acetate is associated with the production of polymers and copolymers, mainly poly(vinyl acetates) used in papermaking,…
Field Calibration of DP Flowmeters: Best Practices
Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…
A flexible, origami-based fuel cell
Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…
A solvent-free process makes battery electrodes
Conventional processes for manufacturing battery electrodes use toxic solvents and require a lot of space and energy. In contrast, DRYtraec — a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology (IWS; Dresden, Germany; www.iws.fraunhofer.de) —…
Chementator briefs
'New food' GEA AG (Düsseldorf, Germany; www.gea.com) has received a contract from Novozymes A/S (Copenhagen, Denmark; www.novozymes.com) for a turnkey fitting of a major new plant to produce plant-based proteins for the plant-based food industry. The high double-digit million-euro order…
Two new semiconductor-based nanomaterials synthesized for the first time
The latest generations of computer chips are only a few nanometers in size and are becoming ever more energy-saving and powerful as a result of progressive miniaturization. Since the etching processes traditionally used in chip production are increasingly reaching their…
Integration of CO2 direct air capture and alcohol-to-jet fuels manufacturing
A feasibility study is underway for the world’s first commercial facility that integrates direct air capture (DAC) of atmospheric carbon dioxide with gas fermentation of CO2 and production of aviation fuels. LanzaTech (Chicago, Ill.; www.lanzatech.com) and Carbon Engineering (Squamish, B.C.;…
Safer, more sustainable control of runaway polymerization
Runaway polymerizations of acrylic monomers can lead to catastrophic fires and explosions in production plants and storage terminals, as well as during transportation. Special chemical products called shortstop inhibitors are used to minimize the likelihood of runaway polymerization reactions. A…
Sanitize, Analyze and Optimize Bioprocessing Operations
Better designs and improved monitoring and control technologies lead to higher efficiencies While bioprocessing can be challenging due to the sanitation requirements and exacting processes, new technologies are allowing bioprocessors to more easily sanitize, analyze and optimize their processes in…
