Making bioethanol directly from starch
Today, the cost of enzymes continues to make bioethanol uncompetitive as a fuel. Eliminating the need for amylases, which are used to hydrolyze starch into fermentable sugars, would be a key step toward reducing the operating costs for producing bioethanol.…
Air-capture of CO2 using waste process heat
Carbon-negative technology being commercialized by Global Thermostat LLC (New York, N.Y.; www.globalthermostat.com) removes carbon dioxide directly from the atmosphere using low-cost waste process heat from industrial processes. The technology works in a similar fashion to cogeneration approaches and could transform…
A desalination membrane that is resistant to chlorine
The major drawback of existing membranes for desalination plants is that the membranes are not tolerant of oxidizing agents, such as chlorine. To overcome this drawback, a team of researchers from the University of Melbourne (www.unimelb.edu.au) and CSIRO (Melbourne, Australia;…
A pulsation dampener that decreases pump energy consumption
A new pulsation dampener benefits from a design that can reportedly decrease energy usage. The Expulse, a flexible, inline pulsation dampener recently released by Flowrox Inc. (Linthicum, Md; www.flowrox.us), consists of a reinforced outer hose and an expansive inner hose,…
Construction to begin on biomass-to-fuels facility
Construction is set to begin on a biorefinery in Oregon this summer that will manufacture bio-based jet fuel and diesel from forest and sawmill residues. When it begins producing biofuels at the end of 2016, it will be capable of…
New cryogenic technology for cooling superconducting cables
Industrial gases specialist Messer Group GmbH (Bad Soden, Germany; www.messergroup.com) has developed a new cryogenic technology that makes it possible to use liquid nitrogen (LN2) to cool high-temperature superconducting (HTS) cables down to –209°C, which is significantly lower than that…
April Chementator Briefs
Nanocellulose pilot Sappi Ltd. (Johannesburg; South Africa; www.sappi.com) will build a pilot-scale plant for low-cost nanocellulose (Cellulose NanoFibrils; CNF) production at the Brightlands Chemelot Campus (Sittard-Geleen, the Netherlands; www.brightlands.com). The pilot plant will test the manufacturing of dry re-dispersible CNF…
Modified MOFs could cut carbon-capture costs in half
Chemists from the University of California, Berkeley (UC Berkeley; www.berkeley.edu) have modified a metal-organic framework (MOF) compound with diamines, which enables the material to be tuned to absorb CO2 at different temperatures, such as from air at room temperature, or…
MOF material improves CO2-capture effectiveness
Industrial CO2 capture is currently done by absorption in liquid amines, such as monoethanolamine. However, absorption-based carbon capture carries a significant energy penalty for regenerating CO2 in a stripping column — power plants can lose 20–30% of their energy output…
A new primary aluminum-production process to be piloted
Last month, Hydro ASA (www.hydro.com) entered into a contract with Multiconsult (both Oslo, Norway; www.multionsult.no) for engineering services for Hydro’s planned pilot plant at Karmøy, Norway. The Karmøy pilot aims to verify what Hydro calls the worlds most energy- and…
