Adsorption
Successful adsorber design requires information about certain adsorbent properties, including: adsorbent densities and void fractions; isotherms or other equilibrium data; and data on mass-transfer kinetics and fixed-bed dynamics. Here, these adsorbent properties are explained, along with corresponding equations. Densities and void Fractions Three densities are relevant: bulk, particle and solid. There are...

Putting MgH2 in your fuel tank
Techno Bank Co., Ltd. (Tokyo, Japan; edlinks.che.com/6897-537) has developed a new supply, storage, and transport system for safely handling a high capacity of hydrogen in fuel-cell applications. The system — a cassette containing nano-sized powder of magnesium hydride (MgH₂) — is said to be safer than alternatives, such as insulated cylinders of liquid H₂ at 700 bar. Other methods being...

Landfill yields LNG for vehicle fuel
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...

A new PSA process to recover high-purity H2 from steam reformers
Kobe Steel Ltd. (Kobelco; Tokyo; edlinks.che.com/6896-532) has developed a process to recover hydrogen from methane steam reformers with purity that is sufficiently high for use in fuel cells. The key to the process is a proprietary carbon-monoxide adsorbent for H₂ pressure-swing adsorption (PSA), which Kobelco developed jointly with Kansai Coke and Chemicals Co. (Amagasaki, Japan). In conventional PSA...

A new processing strategy for the wine industry
Winemaking still involves traditional batchwise processing steps, such as batch fining with bentonite clay to prevent heat instability in protein haze formation. This is typically done by adding “rule-of-thumb” amounts of clay, allowing it to settle and decanting the wine. Now, researchers from the Deparment of Chemical Engineering, Adelaide...

Modeling gas-liquid separation
Process System Enterprise Ltd. (PSE; London, U.K.; edlinks.che.com/5825-542) has launched the latest of a series of gPROMS Advanced Model Libraries (AMLs) for Gas-Liquid Contactors (GLCs). This “open model” library of high-fidelity, non-equilibrium-component models covers a wide range of gas-liquid-separation operations, including conventional packed columns for...
