Sorbent materials are used commercially for bulk separation, as well as purification of both liquids and gases. This one-page reference provides manufacturing and application information on the most widely used industrial sorbent material — activated carbon. Four types of generic sorbents have dominated industrial adsorption: activated carbon, zeolites, silica gel and activated alumina. By worldwide...

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...

Techno Bank Co., Ltd. (Tokyo, Japan; 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...

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.; 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...

Kobe Steel Ltd. (Kobelco; Tokyo; 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...

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...

Process System Enterprise Ltd. (PSE; London, U.K.; 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...
