Chementator: Fuel from CO2    

UOP LLC (Des Plaines, Ill.; edlinks.chemengonline.com/7368-542) has partnered with the University of Southern California’s (USC) Loker Hydrocarbon Research Institute (Los Angeles; edlinks.chemengonline.com/7368-543) to develop and commercialize new technology to transform carbon dioxide into clean-burning alternative fuels. USC developed fundamental chemistry…

Chementator: A Fat Shortage in 2008?  

Animal and vegetable oils and fats are a key renewable feedstock for making detergents, soaps, lubricants, paints, coatings, cosmetics and pharmaceuticals, as well as additives for plastics, rubber and textiles. However, a consequence of the current EU renewable-energy policy is…

Chementator: Coal-Mine Vent Air

Megtec Systems (Glen Waverly, Victoria, Australia; edlinks.chemengonline.com/6902-542) has announced the first power plant fueled by methane emissions from coal-mine ventilation air. Traditionally, CH4 released during coal excavation requires dilution in ventilation air because it is explosive at concentrations between 5…

Chementator: With These Turbines, Waste Energy Can Now Be Recovered from Saturated Steam  

Traditionally, the cogeneration of steam and electricity has been restricted to plants that generate superheated steam, making the recovery of energy losses from saturated steam impossible for many industrial sites ranging from distilleries to pharmaceutical plants and pulp-and-paper mills. At…

Chementator: New Pyrolysis Method Improves Carbon Black Recovery from Scrap Tires

The standard temperature range for waste-rubber pyrolysis has been reported as 480 – 1,740ºF. Within 480 – 750ºF, shredded tire scrap decomposes into increasing amounts of gases and oil; and above 750ºF, oil and solid char yields can decrease relative…

Chementator: A Way to Convert Depleted Oil Wells into Natural-Gas Wells

The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a…
