Amine-containing solids have been investigated as promising adsorbents for CO2 capture, but existing amine-containing adsorbents degrade by oxidation, making them unreliable for repeated CO2 adsorption-desorption cycles over a long period. The low stability requires the continuous addition of fresh adsorbents,…
As the volume of discarded electronic gadgets grows, efforts are underway to recover the precious resources trapped inside It should come as no surprise that the fastest growing part of the world’s domestic waste stream is e-waste — discarded products…
Forward Osmosis Last month, Bioindustrial Innovation Canada (BIC; Sarnia, Ont.; www.bincanada.ca), Forward Water Technologies (FWT; www.forwardwater.com) and GreenCentre Canada (GCC; Kingston, Ont.; www.greencentrecanada.com) announced a private investment into FWT, supporting the commercial scaleup of a proprietary forward-osmosis technology. The initial…
Data analytics, connectivity and machine learning are helping processors maintain facilities in a more cost-efficient way Modern technologies, such as smart sensors, data analytics, the industrial internet of things (IIoT) and machine learning, are changing the face of maintenance to…
A filter for water purification that can replace, with a single step, the complex, time-consuming and multi-stage processes currently needed, has been developed by a team from CSIRO Manufacturing (Sydney, Australia; www.csiro.au), led by Dong Han Seo. The team has…
A thermal-membrane process system, based on the Joule-Thompson effect (JTE) for treating wastewater with high salinity or with a high-level of inorganic contents has been developed by Thermosift Engineering Pvt. Ltd. (Asaripallam, Tamil Nadu, India; www.thermosift.com). The system operates at…
C2H2 hydrogenation Last month, Clariant (Munich, Germany; www.clariant.com) launched OleMax 260, a new selective acetylene-hydrogenation catalyst, which is said to have extremely high ethylene selectivity and operational stability. Specially developed for ethylene producers with “front-end” process configurations, OleMax 260 offers…
Plant Watch Total and Sonatrach begin engineering studies for joint petrochemicals project May 11, 2018 — Total S.A. (Paris, France; www.total.com) and Sonatrach (Algiers, Algeria; www.sonatrach.com) will launch engineering studies for a petrochemical project in Arzew, Algeria. The project includes…
One of the major obstacles to making hydrogen economically by splitting water is the high cost of noble-metal electrodes. Less expensive, non-noble metals only function as electrocatalysts under alkaline conditions, where the reaction requires more electricity. Now, professor Ryoichi Ito…
Researchers from the Chinese Academy of Sciences (Beijing, China; www.cas.cn), led by professor Ying-Jie Zhu, have reported a “smart” fire-alarm wallpaper prepared using ultralong hydroxyapatite nanowires and graphene oxide thermosensitive sensors. At room temperature, the graphene-oxide sensor is an electrical…
