Plans are underway to field-test a process that removes more than 90 % of the carbon dioxide from power-plant flue gas, while reducing both the energy input and operating costs by 50 % compared to conventional amine-based CO2-scrubbing technology. The so-called carbonate-looping process has undergone four years of testing in a 1 MWth pilot plant at the Technical University of Darmstadt (Germany...

The volume of heavy, sour crude oil processed by North American refineries is steadily increasing, and along with it a commensurate demand for hydrogen to upgrade that oil. A steam-reforming process that would allow refiners to produce their own H2 from heavy oil and residuum is being developed by TDA Research, Inc. (Wheat Ridge, Colo.; www.tda.com). Currently, refiners make a lot of their own hydrogen by...

Aither Chemicals LLC (South Charleston, W.Va.; www.aitherchemicals.com) is planning to build a commercial-scale plant based on a catalytic ethane-cracking process that uses 80% less energy and generates 60% less carbon dioxide than conventional steam-cracking of ethane.  The company has refined a mixed metal-oxide catalyst that was originally developed by Union Carbide in the 1980s. The catalyst...

Air Fuel Synthesis Ltd. (AFS; Darlington, U.K.; www.airfuelsynthesis.com) has recently demonstrated a process for producing carbon-neutral liquid hydrocarbon (HC) fuel from air-captured carbon dioxide and hydrogen. The proof-of-concept demonstration facility, located at Teesside, England produces 5–10 L/d of liquid HCs. The next step of the company’s three-year (2012–2015)...

Two dissimilar iron-making methods — a conventional blast furnace using coke from coal, and gas-based direct reduction of iron ore — are combined in a process being developed by Midrex Technologies, Inc. (Charlotte, N.C.; www.midrex.com) and Praxair Inc. (Danbury, Conn.; www.praxair.com). Designed to use offgases from the coke-making operation in integrated steel mills, the process offers three...

The production rate (per amount of catalyst) for generating liquid hydrocarbons from syngas by the Fischer-Tropsch (F-T) process, using a slurry reactor or tubular reactor, is generally limited to about 30% of the maximum rate. The restraining factor is heat removal from the highly exothermic reaction, says Steven Vallee, chemical applications engineer for Chart Energy & Chemicals Inc. (La Crosse...

Technology originally developed for dewatering algae has shown success in separating hydrocarbons from produced water that results from oil and gas drilling. The method could be used in treating produced water for onsite re-use as hydraulic fracturing fluid. To harvest oil from algae, OriginOil Inc. (Los Angeles, Calif.; www.originoil.com) developed an electroflocculation...

The technology surrounding a hydrolysis- and fermentation-based process that is capable of utilizing municipal solid waste (MSW) and biomass waste to produce cellulosic bioethanol at low cost is now available for licensing from its developer, TMO Renewables Ltd. (Guildford, U.K.; www.tmo-group.com). Several of the cost-saving measures depend on the capabilities of a heat-loving bacterium that has been...

A novel cold-dry process makes possible the utilization of fine form-factor silicon, such as granules and sand-like fines, in the production of high-purity polysilicon for solar photovoltaic cells and semiconductors, where such fine-grained material would normally have to be sent back up the supply chain rather than into the crucible. The patent-pending drying system, known as FlashDry, was developed by...

Recovery boilers, in which pulp and paper companies burn spent black liquor from the kraft pulping process to recover and recycle sodium and sulfur, are a bottleneck in many paper mills. The reason is that they operate at their upper limit of heat flux into the boiler tubes, thus preventing an increase in the mills’ output, explains John Blackburn, co-founder of Liquid Lignin Co. (LLC, Charleston...
