Theres a growing trend toward generating electricity from biogas (see pp. 15–17), but roughly half of the total energy content of the fuel is released as heat, which is dissipated into the atmosphere unused. To improve the overall efficiency, researchers…
The research groups of professor Yasuyuki Tsuji and assistant professor Tetsuaki Fujihara at Kyoto University (Japan; www.ehcc.kyoto-u.ac.jp) have developed a copper-catalyzed reaction for synthesizing carboxylic acids, such as acrylic acid, using carbon dioxide as a raw material. The reaction involves…
A group of scientists from Fudan University (Shanghai, China; www.fudan.ac.cn) China, has reported what it claims to be the first example of artificial single-molecular water channels that can transport water across lipid membranes. Transmembrane water transport — through water channel…
A recently launched, polymer-coated, fumed silica additive improves the performance of structural adhesives — those designed to bear loads. The new additive is capable of reducing the adhesive’s application viscosity, while simultaneously improving its ability to maintain a bead profile…
This bioprocessing tubing is weldable Watson-Marlow Tubing, PureWeld XL tubing is a weldable tube for the biopharmaceutical and pharmaceutical industries, and is designed for high-purity and secure peristaltic pumping. A high-quality tube capable of completely secure welding, PureWeld XL allows…
Corrosion is a large and complex issue that is critical to the chemical process industries (CPI) as well as other industry sectors. Corrosion not only affects personal property like cars and homes but also affects commercial assets such as storage…
Among all the engineers who will be involved in the purchase of a mixer or blender next year, roughly half will welcome a change in their production method. The other half will be determined to prevent it. Searching for the…
Compressible flow in pipes is common in the chemical process industries (CPI) and is typically associated with density changes in gases that are subjected to pressure variations. Gas flow conditions can be described using an adiabatic or isothermal flow equation.…
Throughout the chemical process industries (CPI), the need to drain a tank or process vessel arises. In batch-type plants, it is a regular occurrence and is one factor that affects the total cycle time per batch and ultimately the entire…
India holds large reserves of low-grade sulfide copper ore containing 0.3 wt.% copper, which cannot be processed through conventional routes since the cut-off grade for treatment in concentrators is about 0.45 wt.%. India is in short supply of copper and…
