  Aiding crystal growth Scientists at Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) have patented a method for absorbing hydrogen fluoride gas to enhance crystal growth. HF is commonly added to precursors to transfer crystalline order from a substrate to a growing material, but buildup of the gas can slow down or even stop the reaction. Simply venting the HF is not practical because...

A multi-stage wet scrubber that combines the removal of sulfur, hydrogen chloride, sulfuric acid mist (SAM) and particulate matter (PM) in a single unit has reduced sulfur dioxide emissions by an average of 99.7% in its first large-scale commercial installation on a coal/oil-fired swing boiler. PM emissions were reduced to 0.005 grains/dscf (dry standard cubic feet; 12.5 mg/Nm3), according to Kimmo...

A process that produces 75–85 gal of ethanol per dry ton of mixed cellulosic waste feed will be commercialized by BlueFire Ethanol (Irvine, Calif.; www.bluefireethanol.com). The plant, to be built in Lancaster, Calif., will convert 130 dry ton/d of feed (post-sorted municipal solid waste, including green waste) into 4-million gal/yr (about 12,000 gal/d) of ethanol when it goes into production in the...

Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) has signed a design contract with an undisclosed client in China for a new plant that will produce substitute natural gas (SNG). When the plant comes on stream in 2011, it will produce close to 180,000 Nm3/h of SNG using Topsøe’s methanation process, called TREMP. The plant will be the first large-scale order for TREMP technology, says...

Incineration is becoming the only viable method for sewage sludge disposal as landfilling or spreading sludge onto farmland is no longer permitted in some countries. Today, sludge is commonly incinerated in large, centralized incinerators or as an additive in coal-fired power plants or cement kilns. An alternative to these costly and inconvenient options — small, localized incinerators — has...

Transport systems that can encapsulate medications for release when and where needed are the subject of much research and development, especially for two potential synthetic vessels: liposomes and multilayered polymer capsules. Both, however, entail limitations. The permeability of polymer capsules, although partly desirable, also makes them unsuitable for providing a protective barrier for small drugs and...
