An organic waste-to-biogas system to be scaled up in first installation

Construction will soon begin at a site in Korea on an anaerobic digester technology that converts organic waste and biomass to methane at high conversion rates, while also producing a fertilizer stream. Technology developer Bioconversions Solutions LLC (Exton, Pa.; www.bioconversionssolutions.com)…

Mastering the Challenges of Air-Sensitive Materials

While air-sensitive materials may not be a part of every chemical process, certain catalysts, OLED (organic light-emitting diode) applications, inert gas welding, lithium-ion battery applications and other chemical processes do, indeed, require the inclusion of air-sensitive materials. And, when such…

Integrally Geared Compressors in the CPI

In an integrally geared centrifugal compressor (Figure 1), several impellers are mounted on the ends of high-speed pinion shafts, which are rotated by a bull-gear. Each impeller’s casing is mounted directly on the horizontally split gear casing. As is the…

Precise dosing with multi-port, fluoroplastic valve blocks

This multi-port valve block from the iComLine Series is made of ultra-pure PVDF and features innovative seat-diaphragm technology with PTFE. This combination allows very heavy-duty switching cycles and temperature resistance up to 150°C — features that are not possible with…

Protect vacuum pumps from contamination with these traps

These vacuum inlet traps protect pumps across many applications, from laboratory settings to scalable production systems. The inlet vacuum traps feature user-selectable filter elements for removing the corrosive gases and abrasive particles created by processes that use volatile organic compounds…

Mass Transfer in Fermentation Scaleup

How big can a fermenter get? And what would the biggest fermenter look like? The answers to these questions depend upon how the requirements of heat transfer, mass transfer (gas-to-liquid), and momentum transfer (mixing) are met. In an earlier article…

Bio-isobutene fermentation process to be piloted

Construction is underway in France on a pilot plant for what is believed to be the first fermentation process capable of directly producing the light olefin isobutene. Global Bioenergies (Evry, France; www.global-bioenergies.com) expects to begin operations of a 500-L fermentation…

This pathway from cellulose to p-xylene eliminates saccharification step

A new chemical process is set to create bio-based p-xylene from cellulosic waste. Micromidas (West Sacramento, Calif.; www.micromidas.com) opened a pilot plant in December 2013 that converts cellulosic waste materials, such as rice hulls, switchgrass, sawdust and cardboard to bio-based…

A new spin on enzymatic reactions

A new process-intensification technology to accelerate the rate of enzymatic reactions has been developed by researchers from the Dept. of Chemical Engineering, University of Bath (U.K.; www.bath.ac.uk). The so-called spinning cloth disc reactor (SCDR) is based on, but extends the…
