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 technique that displaces the oil and stores the greenhouse gas. Now, a completely different approach to monetizing the carbon is being considered by Inpex Holdings Inc. (Tokyo...

In Malaysia, the raw material for biodiesel production has been palm oil. However, making biodiesel can conflict with the oil’s use as food, and growing palm oil (even for food) has caused the destruction of tropical forests in Borneo, Sumatra and other regions. A team from the Dept. of Chem. Eng. at the Universiti Teknologi Petronas, (Perak, Malaysia...

Technology to copolymerize carbon dioxide and propylene oxide (PO) was first discovered in 1960s, but has not been commercialized due to the formation of cyclic propylene carbonate (CPC) by a “back-biting” reaction, which leads to the formation of unstable, low-molecular-weight copolymers. This limitation has essentially been eliminated, thanks to a new catalyst developed by Professor Kyoko...

Within five years, four large power plants in Europe will be outfitted — for testing at the pilot scale — with energy-efficient CO2-filtering membranes that are being developed at the Norwegian University of Science and Technology (NTNU; Trondheim; edlinks.che.com/6901-531). Professor May-Britt Hägg, head of the membrane research group (MEMFO) at NTNU’s chemical engineering...

  Silverado Green Fuel, Inc. (Vancouver BC, Canada; edlinks.che.com/6900-533) has entered into a memorandum of understanding with the Mississippi Development Authority (Jackson) to build a demonstration plant in Choctaw County to produce a clean-burning “green” liquid fuel from the state’s plentiful lignite reserves.

DuPont (Wilmington, Del.; edlinks.che.com/6900-531) has acquired hydrotreating technology for desulfurizing motor fuels and hydrocracking intermediate refinery streams from Process Dynamics, Inc. (Fayetteville, Ark.). The IsoTherming Hydroprocessing Technology differs from other hydrotreating processes in that hydrogen is dissolved in the liquid feed before the liquid enters the reactor, so the reactors...

Although halons (brominated or chlorinated fluorocarbons) are widely used as fire suppressants and foaming agents, they also contribute to stratospheric ozone depletion. However, halons are potentially valuable chemicals that should not be destroyed, but rather converted to reusable chemicals, says Bogdan Dlugogorski, professor of chemical engineering in the school of...

What is billed as the world’s first plant to produce liquefied natural gas (LNG) from landfill gas is now being commissioned in Irvine, Calif., by Prometheus Energy Company (Seattle, Wash.; edlinks.che.com/6897-540). The first module is expected to reach its capacity of around 5,000 gal/d (about 750 scf/min of gas) by fall, says Dan Clarkson, vice-president. Other modules will be added later to use...

            Many coal-fired power plants make gypsum and construction materials. But they should also consider manufacturing hydrochloric acid and ethanol. Furthermore, they should consider substituting biomass and waste organics for up to 10% of the coal. The combination of these initiatives would make coal plants much “greener.” Coal is the cost effective way to...
