Chementator: A Process for Desulfurizing Natural Gas  

A process in which sulfur is extracted from natural gas in the field and converted to sulfur dioxide, which is then injected into the gas reservoir and reacts with hydrogen sulfide in situ to produce elemental sulfur, has been developed…

Chementator: A Cellulosic-Ethanol Demonstration Plant Enters Startup Phase    

Verenium Corp. (formerly Celunol; Cambridge, Mass.; edlinks.chemengonline.com/7372-537) is starting up a 1.4-million gal/yr demonstration-scale facility at Jennings, La., which will produce ethanol from regional feedstocks (including sugarcane bagasse and specially bred "energy cane") via proprietary cellulosic-ethanol technology. The technology was…

Chementator: Foundation for SIF Demonstrations    

This month, the newly released Foundation for Safety Instrumented Functions (SIF) was demonstrated at Shell Global Solutions (Amsterdam, Netherlands) — one of several demonstrations planned by the Fieldbus Foundation (FF; Austin, Tex.; edlinks.chemengonline.com/7372-545). In Amsterdam, engineers constructed a DCS-controlled demo…

Editor’s Page: Go green, but be realistic  

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…

Technology Showcase: Biofuels Face a Carbon Certification Challenge

Investment, production and consumption of biofuels are booming, thanks mainly to American and European governments’ subsidy and promotion. In part this is driven by fear of environmental enemy number one — global warming. The simple, conventional wisdom is that biofuels…

Newsfront: Teaching an Old Dog New Tricks

  While it may be one of the oldest chemical processes known to mankind, fermentation is getting a high-tech face lift as industrial biotech firms put a fresh spin on the age-old technology in an effort to develop advanced products…

Environmental Manager: A Checklist for Safer Chemical Batch Reactions

A good understanding of the reaction chemistry is needed for a safe process design It is a fact that safety-related incidents do occur in the chemical process industries (CPI). These incidents have, in part, led to increased attention to reactive-chemical…

Chementator: An ammonia-based CO2-capture process moves several steps closer to commercialization  

Last month, the first pilot project that used chilled ammonia to capture carbon dioxide from the fluegas (FG) of a coal-fired power plant started operating at the 1,210-MW We Energies’ Pleasant Prairie power plant in Wisconsin. Alstom (Windsor, Conn.; edlinks.chemengonline.com/7371-531)…

Chementator: Halogenated activated carbon reduces mercury emissions from a coal-fired plant  

In its first full-scale test on a coal-fired power plant, halogenated activated carbon (AC) made by ADA-ES, Inc. (Littleton, Colo.; edlinks.chemengonline.com/7371-537) has reduced mercury emissions by more than 90%. The significance of the results is that the plant burns western…

Chementator: A platinum-free catalytic converter    

Nippon Steel Materials Co., Ltd. (NSM; Tokyo, Japan; edlinks.chemengonline.com/7371-538) has developed a new catalyst for combustion engines that contains 70% less precious metals than conventional catalytic converters. The catalyst is expected to not only lead to lower costs, but also…
