Chementator: Catalyst loading
TubeMaster, Inc. (Louisville, Ky.; edlinks.chemengonline.com/7373-547) has filed U.S. and foreign patents for Dog-leg — claimed to be the world’s first articulating catalyst-loading device that permits loading of single and multi-layer catalyst to any height or outage, regardless of reactor vertical-head…
Chementator: A dynamic way to reduce NOx emissions from FCCs
A system for controlling oxides-of-nitrogen (NOx) emissions from catalyst regenerators in fluid catalytic crackers (FCCs) has cut NOx output to below 40 ppm (and as low as 25 ppm under certain conditions) in its first commercial installation, according to its…
Chementator: A propane-based AN process makes its commercial debut
This summer, Asahi Kasei Chemicals Corp. (AKCC; Tokyo, Japan; edlinks.chemengonline.com/7373-532) plans to begin construction on a plant for producing 200,000 m.t./yr of acrylonitrile (AN) and a plant for making 70,000 m.t./yr of methyl methacrylate (MMA), at Map Ta Phut, Rayong,…
Chementator: Cellulosic ethanol
Dupont (Wilmington, Del.; edlinks.chemengonline.com/7373-533) and its partner Genencor (Palo Alto, Calif.; edlinks.chemengonline.com/7373-534), a div. of Danisco A/S, plan to invest $140 million to integrate the pretreatment process and fermenting organism — developed with the National Renewable Energy Laboratory (NREL: Golden,…
Chementator: Drying at the speed of light
After several years of proven operation in the food- and nutritional-products industry, a patented drying technology is now ready to be applied for any liquid or slurry product. Developed by MCD Technologies, Inc. (Tacoma, Wash.; edlinks.chemengonline.com/7373-535), the Refractance Window (RW)…
Chementator: Scaleup is set for a natural-gas-treating process that freezes out CO2
