The heat transfer sufaces of coal-fired process heaters and boilers often undergo severe fouling. If left intact, such deposits, consisting of slag from mineral matter contained in the coal, can reduce heat-transfer-surface availability, reduce thermal efficiency and cause corrosion. If the deposits are adherent and cannot be removed by conventional steam soot-blowers, shutdown and more rigorous cleaning...

The world’s first commercial plant to produce liquid fuels by direct coal liquefaction is now being started up in Majata, Inner Mongolia, by Shenhua Group (Beijing). Designed to produce 25,000 bbl/d of syncrude from 4,300 metric tons per day (m.t./d) of coal, the plant was operated for a 300-h trial at the beginning of this year, then was shut down for modifications. If the current startup goes well...

Algae offer a ubiquitous, renewable source of oil for fuels and various chemical products ( CE, September 2008, pp. 22–25), but the extraction of oil from the algae cells is an energy-intensive process that involves dewatering and drying the biomass, followed by solvent extraction. Now, a one-step method that breaks the algae cells and liberates the oil without the need for dewatering or solvents has...

Petroleum refiners throughout the world are faced with increasing uncertainty regarding future refining margins, crude prices and project costs. These factors, along with falling demand for refined products, a global recession, and tighter credit markets, are forcing global refiners to reconsider, postpone, or cancel expansion projects. At the same time, mandated reduction of sulfur levels in refined...

Researchers at United Environment & Energy (UE&E; Horseheads, N.Y.) have developed a catalyst for the efficient conversion of algae to biodiesel. The mixed-metal oxide catalyst (comprised of metals that are resistant to corrosion yet reactive) facilitates the transesterification of algae oil and methanol. The mechanism for the reaction over the solid...

Because temperature control is important in any process, a water-cooling system is a common component in chemical processing plants. For facilities located near coastal areas, the tendency is toward the use of seawater instead of river water for cooling purposes. Seawater has the advantage of having nearly a constant quality (chemical analysis), nearly a constant temperature and is available in large...

CSIRO Energy Technology (Newcastle, New South Wales, Australia; www.csiro.au) is developing a solar-powered air conditioning unit for residential use, using a desiccant-evaporative process to provide cool and dehumidified air. Thermally driven ab- or adsorption chillers are commonly used to provide cooling using heat, but these entail disadvantages: they are expensive, bulky, they produce chilled water...

A process that produces hydrogen from coal with close to 80% energy conversion efficiency, plus coproduction of a carbon-dioxide-rich stream for sequestration, is being developed at Ohio State University (Columbus, Ohio; www.osu.edu). This compares with around 60% conversion efficiency for traditional coal gasification processes, says Fanxing Li, a research associate and co-inventor of the process along...
