Retrofit unit boosts ethane and propane recoveries in natural gas plants

Using a workhorse technology known as the gas-subcooled process (GSP), most natural gas plants recover between 85 and 90% of ethane in raw natural gas streams. Honeywell UOP (Des Plaines, Ill.; www.uop.com) has developed a modular retrofit unit designed to…

Mimicking cell behavior with functionalized surfactants

Active surfactants are those that are responsive to an external stimulus, such as temperature, light, electric or magnetic fields or chemical agents. Scientists from the Institute for Basic Science (Daejeon, South Korea; www.ibs.re.kr) have developed surfactants based on functionalized nanoparticle…

Gas sensors get a big boost in sensitivity

It has been a challenge to find materials that can reliably detect volatile organic compounds (VOCs) and toxic gases in air at the parts-per-billion (ppb) level, or that can be used for therapeutic diagnosis from breath analysis. That’s because two…

These batteries can handle the cold

Lithium-ion batteries based on intercalation compound electrodes exhibit poor performance at temperatures below 0°C. Insufficient ionic conductivity and freezing of the electrolyte are generally seen as the main reasons for the poor performance of rechargeable batteries at low temperatures. Although…

A more direct chemical route to ketones

Using a simple, ligand-free palladium catalyst system, researchers at McGill University (Montreal, Que., Canada; www.mcgill.ca) have demonstrated that metal carbonylation — a core chemical reaction for many industrial products — can be used to synthesize ketones directly from hydrocarbons. The…

A push for ‘green’ steel

Last month, the so-called Hybrit initiative (www.hybritdevelopment.com) was given the go-ahead to build a pilot plant for making fossil-free steel. The announcement follows a pre-feasibility study conducted by Swedish partners SSAB AB (Stockholm; www.ssab.com), LKAB (Luleå; www.lkab.com) and Vattenfall AB…

‘One-pot’ synthesis of conjugated polyenes

The research group of professor Masafumi Hirando at Tokyo University of Agriculture and Technology (TUAT; Koganei City, Japan; www.tuat.ac.jp) has performed the world’s first one-pot synthesis of conjugated polyenes, which normally require at least seven steps by conventional methods. This…
