Newsfront: A Surge in U.S. Refining Capacity  

    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…

Technology Showcase: Carbon Capture and Storage

  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…

An Integrated Approach to Industrial Security

To many, the concept of a "smart plant" involves integrating critical process subsystems and instrumentation with the goal of streamlining operations, increasing production and, simply put, making more money. But looking at the bigger picture, the true goal of having…

Facts at Your Fingertips: Acid Storage

Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks. Horizontal, carbon-steel ASME-type tanks of 10,000 — 40,000 gal capacity should have a plate thickness of…

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…

Chementator: Switchgrass to syngas  

Although theoretically promising 80% more energy than is required to grow and convert to cellulosic ethanol, switchgrass has proven to be a difficult fuel source to break down cost effectively. With $1 million from the U.S. Depts. of Agriculture (USDA)…

Chementator: Sugar-beet pulp may cut the cost of biodegradable plastic    

Sugar-beet processors in the U.S. generate approximately 40 million tons of fiber-rich sugar-beet pulp every year as a byproduct of sucrose extraction. Most of it is used as livestock feed or in pet food. Researchers with the U.S. Agricultural Research…

Chementator: CO2-capture demo…  

Basin Electric Power Cooperative (BEPC; Bismarck, N.D.) has selected the CO2-capture technology of Powerspan Corp. (Portsmouth, N.H.; edlinks.chemengonline.com/7371-546) for a commercial demonstration at BEPC’s Antelope Station coal-fired power plant, located near Beulah, North Dakota. Approximately 1 million ton/yr of CO2…
