Feed injector lowers energy consumption of FCC units

A newly launched feed injector for fluid catalytic cracking (FCC) units at petroleum refineries reduces the oil-side pressure drop and lowers the steam required, enabling facilities to achieve the same performance with lower energy consumption, according to developer Lummus Technology…

Blast-furnace technology aims for carbon neutrality

Primetals Technologies, Ltd. (London, U.K.; www.primetals.com) and thyssenkrupp AG (Essen, Germany; www.thyssenkrupp.com) have signed an exclusive, worldwide cooperation agreement that sees both parties commit to bringing the Sequence Impulse Process (SIP) technology to the market. The SIP technology has been…

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…
