Modern Fermentation and Fermenter Design
With the growth of ‘white biotechnology,’ industrial fermentation processes and large-scale fermenters will play a key role. Presented here are some design considerations In fermentation, microorganisms, animal and plant cells are used to produce chemical compounds. Enzymes, pharmaceutical ingredients, amino…
Production and Demand Challenges for ‘Green’ Hydrogen
Burgeoning demand for hydrogen to support decarbonization goals is straining existing supply chains for industrial gases and prompting companies to adapt quickly to the emerging net-zero-carbon economy The increasing use of hydrogen as a clean energy carrier is causing a…
Selecting Mixing Impellers
Presented here is a brief overview of the considerations involved in matching the right impeller with a given application Matching the right mixing equipment to the material properties and desired process outcome for any liquid-mixing application is the key to…
Chementator Briefs
CO2 liquefaction Last month, Linde Engineering (Pullach, Germany; www.linde-engineering.com) signed a contract with Yara International ASA (Oslo, Norway; www.yara.com) to build a world-scale carbon dioxide liquefaction plant in Sluiskil, the Netherlands. The Sluiskil project forms a key part of Yara’s…
Completely recycled viscose for the first time
Researchers at Lund University (Sweden; www.lth.se) have succeeded in converting worn-out cotton sheets into new viscose fibers using a process that — for the first time — enables all of the viscose to be recycled. Current recycling methods often require…
Carbon-fiber-reinforced polymer boosts interfacial adhesion and recyclability
The high strength-to-weight ratio and robust mechanical properties of carbon-fiber-reinforced polymers (CFRPs) make them attractive for use in wind-power turbine blades, automobile components, and in airplanes and spacecraft. However, challenges — such as weak interfacial adhesion and poor recyclability —…
Recently published books for April 2024
The following list is a selection of recently published books that may have relevance for parts of the chemical process industries (CPI): Processing of Biomass Waste: Technological Upgradation and Advancement. Edited by Angana Sarkar and Ulla Lassi, Elsevier Press, March…
Biomanufacturing process minimizes CO2 loss in fermentation
Fermentation processes provide essential pathways for many chemicals, but are often hampered by high costs and low yields due to CO2 losses. To overcome these concerns, ZymoChem (San Leandro, Calif.; www.zymochem.com) has developed the patented Carbon Conservation fermentation technology. “Typically,…
Chementator briefs
Waste heat Last month, Evonik Industries AG (Essen; www.evonik.com) and Uniper (Düsseldorf, both Germany; www.uniper.energy) launched the Technical Options for Thermal Energy Recovery (TORTE) project in Gelsenkirchen. As one of the first phases of Evonik’s Herne Green Deal to sustainably…
A modularized method to make low-carbon methanol
Stranded methane in waste streams and flare gases at remote processing sites is a promising untapped resource. Now, with a new modular technology, companies can take advantage of this hydrocarbon-containing stream while also reducing their methane emissions. M2X Energy (Rockledge,…
