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 developer, Shell Global Solutions (Houston, Tex.; edlinks.che.com/7373-531). This compares with about 20 ppm for selective catalytic reduction (SCR)...

Petroleum refiners can have the option to produce more diesel fuel or propylene from their fluid catalytic crackers, depending on the demand, through a new process offered by Shell Global Solutions (edlinks.che.com/7373-541). The process enables a typical FCC (processing a large percentage of residual feed) to produce up to 19.3 wt.% light cycle oil (LCO, for diesel fuel) with 10 wt.% propylene, or about...

Accurate temperature measurement is not difficult. It does, however, require you to think about accuracy from specification and selection, all the way up to installation and operation of your temperature-measurement sensor. There are opportunities to improve accuracy during each of these phases, as well as opportunities to accidentally undermine all of your previous improvement efforts. Determining the...

    U.S. petroleum companies are investing in new domestic refining capacity on a scale not seen in decades. Over the next five years the industry will add more than one million bbl/d of distillation capacity (see table), according to the U.S. Department of Energy’s Energy Information Administration (EIA, Washington D.C.; www.eia.doe.gov). "It’s a step change in expansion,"...

  Carbon capture and storage (CCS) is an area of technology that has received national and international attention. CCS is seen by some as a way to reduce carbon dioxide (CO2) emissions into the atmosphere and thereby decrease the threat of global warming. Consequently, proponents have increased pressure on state and federal governments to make such reductions mandatory. Although the benefits of CCS...

Carbone Lorraine (CL; Paris, France; edlinks.che.com/7372-538) is launching a new welded-plate heat exchanger, dubbed Heatex, which features plates made of tantalum CL-Clad. The patented CL-Clad technology involves the brazing of steel onto "reactive" metals, such as tantalum, titanium and zirconium, in order to fabricate columns, reactors and (now) heat exchangers used in corrosive service. Such...

  Industrial furnaces, or direct-fired heaters, are only as good as the burners that supply them with thermal energy for heat transfer and endothermic chemical reactions. This article presents equations that permit calculation of such important burner-operating characteristics as flame length, flame diameter, ignitability, and flameout conditions for both very high and very low velocities. The data...

As spring approaches, the woods around Frankfurt are beginning to get green again. Taking in this annual transformation, it seems like a good time to reflect on how the meaning of the word "green" has changed — through misuse or at least, in my opinion, overuse of the word. Many press releases course through our offices, and more and more (it seems), companies are touting a greener process...
