Ammonia is a crucial chemical feedstock for fertilizer production, as well as a potential energy carrier. However, the current, century-old method of synthesizing ammonia, the Haber–Bosch process, consumes a great deal of energy, operating at high pressures (several hundred atmospheres)…
An adsorption desalination and cooling (ADC) plant has been implemented at Solar Village near the Saudi Arabian capital of Riyadh, by King Abdulaziz City of Science and Technology (KACST; www.kacst.edu.sa). The project to build the plant resulted from a collaboration…
A new alkylation technology that uses ionic liquids as a catalyst has been licensed by Honeywell UOP (Des Plaines, Ill.; www.uop.com), and will be marketed under the tradename Isoalkyl. The technology — developed by Chevron U.S.A. Inc., a subsidiary of…
Toshiba Corp. (www.toshiba.co.jp), Mizuho Information & Research Institute, Inc. (MHIR; both Tokyo, Japan; www.mizuho-ir.co.jp) and 11 other industrial and academic partners have been selected to carry out a five-year project, “Demonstration of Sustainable CCS Technology Project,” sponsored by Japan’s Ministry…
Last month, Weatherly Inc., a wholly owned subsidiary of KBR Inc. (Houston; www.kbr.com) introduced its new dual-pressure nitric acid (DPNA) technology, which enables economically viable production of HNO3 in large scale [over 1,000 metric tons per day (m.t./d)], as part…
Converting natural gas to liquid hydrocarbons can theoretically be accomplished at high temperatures with the help of zeolite catalysts, but the reaction is hindered by two major factors. The conversion to products is thermodynamically limited, and coke formation on the…
Current commercial technologies for separating and purifying p-xylene — an important precursor for polyesters and plastics — from hydrocarbon mixtures involve phase-change techniques that require large amounts of thermal energy. Recently, a research team from Georgia Institute of Technology (Ga.…
Plant Watch BASF expands global production capacity of Ultrason polyarylsulfone September 8, 2016— BASF SE (Ludwigshafen, Germany; www.basf.com) will set up an additional production line for Ultrason polyarylsulfone at its site in Yeosu, Korea. The new line will start up…
Making CO from CO2Professor Rhosuke Suzuki at Hokkaido University (Sapporo City, Japan; www.eng.hokudai.ac.jp) has developed a molten-salt electrolysis process that can produce CO from high temperature CO2 present in the fluegas of industrial furnaces. The process uses a molten salt…
The rising cost of landfilling trash creates a strong incentive to utilize the waste for saleable products. A recently piloted process is an example: the process can convert municipal solid waste (MSW) into a narrow range of valuable aromatic compounds.…
