This company has been awarded a contract to develop special vacuum pumps for the ITER fusion reactor (photo) — a multinational project to further fusion power plants. In order to carry out the plasma reaction, it is necessary to evacuate…
The portfolio of Neles ceramic E-Series control valves (photo), recognized for being extremely erosion resistant, has now been expanded to NPS 8 in. (DN 200) in pressure Class 300 (PN40). The E-series valve is the most erosion-resistant control valve available.…
APSPG tubing is specially formulated to withstand the repeated compression and release actions of peristaltic pumps and offers consistent performance in pharmaceutical, biopharmaceutical and laboratory uses. Made of platinum-cured, low-volatile-grade silicone material, the finished tubing carries the United States Pharmacopoeia…
This company now offers its new SQEx.2 part-turn actuator — the explosion-proof version of its SQ actuator, which was introduced at the beginning of 2013. In line with qualification requirements for hazardous environments, the SQEx.2 meets the European ATEX and…
Pressure to become more flexible and provide shorter cycle times have prompted chemical processors to examine their mixing operations to determine whether there is a way to increase process efficiency via mixing equipment. And, they just might be onto something,…
This company has developed helium recovery units that make it possible to recover and recycle the gas used in leak detection. The recovery of used helium is useful for meeting the environmental certification requirements under DIN EN ISO 14001 and…
Compressible gas flow with significant variation in density along pipes is commonplace in the chemical processing industries (CPI). In designing these pipes for compressible flow, it is important to calculate the pressure loss or maximum gas-handling capacity for safety and…
Would you like to make a quick mental calculation to determine approximate flowrate, velocity, or pipe and duct sizes for many common situations? This article presents two methods for estimating flow characteristics without the aid of charts, tables, calculators or…
A new water-gas shift catalyst has undergone 1,000 h of successful operation in a demonstration carried out by the New Energy and Industrial Technology Development Organization (NEDO, Kawasaki; www.nedo.go.jp) and Hitachi, Ltd. (Tokyo, both Japan; www.hitachi.com). The tests were performed…
Converting CO2 into methane is a way to mimic the natural carbon cycle and close the energy cycle by producing synthetic hydrocarbons (see, for example, CO2 Utilization, Chem. Eng., July 2013, pp. 16–19). However, the Sabatier reaction (CO2 + 4H2…
