Two dissimilar iron-making methods — a conventional blast furnace using coke from coal, and gas-based direct reduction of iron ore — are combined in a process being developed by Midrex Technologies, Inc. (Charlotte, N.C.; www.midrex.com) and Praxair Inc. (Danbury, Conn.;…
Transfinity elastomer composite products specifically are designed for use in anti-vibration applications. These products provide elastomer compound formulators the flexibility to control damping levels and achieve the highest levels of dynamic durability. This new flexibility in material formulation creates opportunities…
A system that continuously produces 10 ton/yr of nanoparticles has been developed by Tadafumi Adschiri, principal investigator at the Advanced Institute for Materials Research (AIMR) and professor at the Institute of Multidisciplinary Research for Advanced Materials and New Industry Hatchery…
The production rate (per amount of catalyst) for generating liquid hydrocarbons from syngas by the Fischer-Tropsch (F-T) process, using a slurry reactor or tubular reactor, is generally limited to about 30% of the maximum rate. The restraining factor is heat…
Petroleum-derived ethylene normally contains traces of acetylene, which interferes with the conversion of ethylene into polyethylene (PE). Because it is difficult to separate it, the acetylene is selectively hydrogenated to ethylene — without subsequent hydrogenation to ethane — using a…
Ajinomoto Co., Inc. (www.ajinomoto.com) and Bridgestone Corp. (Both Tokyo, Japan; www.bridgestone.com) have jointly developed a bio-based, high- cis-polyisoprene synthetic rubber. The two companies began an R&D cooperation in June 2011 to combine their know-how — Ajinomoto’s state-of-the-art fermentation technologies for…
A tube welder for sterile biopharmaceutical applications Sartorius Stedim Biotech The Biowelder Total Containment (TC) system features innovative technology that permits sterile connection of liquid-liquid thermoplastic tubing that has an outer diameter of up to 1 in. and that is…
Materials that tend to harden during mixing cause rapid wear of the machines. The new continuous-motion Druvaflex Ploughshare mixer was developed with such applications in mind. The Ploughshare mixer was equipped with a vessel made of multi-layered, reinforced rubber. Due…
This leading manufacturer of plastic-lined valves and process pumps has expanded its product range of shut-off and control butterfly valves. The company now offers valves with a PTFE disc/stem unit to DN 750 (30 in.) or with a metallic disc/stem…
For pumping demanding materials, this company has launched the IQ series, a low-maintenance product that is easy to use and has low operating costs. The IQ series is designed for industrial applications, wastewater treatment plans and tanker trucks or mobile…
