Making a mercury-removing polymer from industrial waste

Scientists at Flinders University (Adelaide, Australia; www.flinders.edu.au) have synthesized a new polymer that is extremely effective at binding to mercury for removal from water and soil. The new material — called sulfur-limonene polysulfide — is created from a reaction (diagram)…

‘Switchable solvent’ technology is a promising development for advancing forward osmosis

Forward osmosis (FO), whereby a concentrated salt solution is used to “draw” water through a membrane from a less-concentrated salt solution (via osmotic pressure), has the advantage over reverse osmosis (RO) in that high pressures, with the associated pumps and…

Liquid-infused surfaces move toward commercial applications

A set of technologies that create an immobilized thin layer of lubricant on a solid surface, thus enabling highly repellent, omniphobic surfaces, has moved closer to commercial application. Known as slippery, liquid-infused porous surfaces (SLIPS), the technologies can be applied…

A booster bed for Circulating Fluidized-bed Combustors

The efficiency of circulating fluidized-bed (CFB) combustors can be significantly increased by substituting conventional bed material with an ilmenite-based bed material, according to researchers at Chalmers University of Technology (Gothenburg, Sweden; www.chalmers.se). Conventional CFB boilers use silica sand to evenly…

Convert wasted natural gas to liquid fuels

A newly launched technology known as Flare Buster is capable of converting natural gas streams, such as flare gas and stranded gas from remote sites, to synthesis gas (syngas) and then to synthetic crude oil via a Fischer-Tropsch (F-T) synthesis…

Streamline turnarounds with faster catalyst cooling

A new process technology from Aggreko North America plc (Houston; www.us.aggreko.com) aims to make turnarounds at petroleum refineries more cost-effective by decreasing the time required for catalyst cooling. The catalyst materials used for refining operations, such as hydrotreating, hydrocracking and…
