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,…
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…
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…
Plant Watch Arkema to expand polyamide powder production capacity in France June 6, 2018 — Arkema (Colombes, France; www.arkema.com) plans to expand its global production capacity for specialty polyamide powders marketed under the brand name Orgasol by more than 50%…
Many methods have been developed to remove spilled oil and organic pollutants from water, but they all entail shortcomings, such as low absorption ability and poor buoyancy. Now, a team from the School of Light Industry and Chemical Engineering, Dalian…
Digitalization, sustainability, security and safety are at the forefront of innovations in the logistics and supply-chain sectors Ensuring that chemical products reach the correct location at the correct time requires intricate networks of complex logistics and scheduling tasks where several…
Plug-and-produce concepts for automating modular skids may solve integration challenges for modular construction projects Modular construction — both of facilities and process skids — has gained popularity due to its benefits, including speed of delivery and predictability of cost and…
To meet strict sulfur specifications and reduce emissions, amine scrubbing and caustic treatment are frequently used to remove hydrogen sulfide from gas and liquid streams, but these methods are not effective for handling more complex organo-sulfur compounds, such as thiophenes…
The development of denitrification catalysts that can reduce nitrate and nitrite to N2 is critical for sustaining the nitrogen cycle. However, regulating the catalytic selectivity has proven to be a challenge, due to the difficulty of controlling complex multi-electron/proton reactions.…
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…
