These miniature regulators are ideal for gas instruments The compact DM3000 (photo, left) allows flow control systems for process or laboratory instrumentation to be constructed in small spaces. With a flow coefficient (Cv) of 0.1 and a maximum inlet pressure…
Last month, Aspen Technology, Inc. (Cambridge, Mass.; edlinks.chemengonline.com/5826-553) launched its new generation of applications for the design, rating and simulation of heat exchangers: Aspen Tasc+, for shell-and-tube heat exchangers, and Aspen Acol+, for air-cooled heat exchangers. Used for optimizing heat…
Last month, Agilent Technologies, Inc. (Palo Alto, Calif.; edlinks.chemengonline.com/5826-546) launched the 1200 Series liquid chromatography (LC) system, replacing its predecessor, the 1100 Series LC. With more than 60 instrument modules available, the 1200 Series can be configured for all major…
Piping-flexibility and stress analysis are required in the design of most piping systems before the piping is installed in a chemical-process or other plant. It is intended to ensure the safety of the plant and thus protect the…
Process System Enterprise Ltd. (PSE; London, U.K.; edlinks.chemengonline.com/5825-542) has launched the latest of a series of gPROMS Advanced Model Libraries (AMLs) for Gas-Liquid Contactors (GLCs). This “open model” library of high-fidelity, non-equilibrium-component models covers a wide range of gas-liquid-separation operations,…
Asset management means different things to different people, but in the chemical process industries (CPI) it’s all to do with making the most of expensive equipment. Asset management is frequently used as another term for maintenance, especially of the proactive…
A prototype of what is called the world’s fastest, wide-ranging hydrogen gas sensor has been constructed by a team of researchers, led by Professor Kazushi Yamanaka at the Dept. of Materials Processing, Tohoku University (Sendai, Japan; edlinks.chemengonline.com/5828-531), together with Toppan…
The EDDL (electronic-device-description language) Cooperation Team (ECT; Karlsruhe, Germany; edlinks.chemengonline.com/5828-532) has released Phase 1 EDDL enhancement specifications. The enhancements on the existing EDDL include new capabilities, such as graphs, charts and images, the possibilities for archive data, and an EDD…
In process engineering and design, thermodynamics theory is applied to real and complex chemical-process applications. Software design simulators, such as HYSYS, PROII and Aspen Plus, serve as powerful tools that simplify process thermodynamic calculations. They eliminate the need…
Measure more than pH with this non-glass meter This multiparameter meter measures pH, temperature, conductivity, total dissolved solids and salinity. Featuring a stainless steel pH probe and solid-state conductivity electrode, the IQ170 (photo, far left) is NEMA4X rated and can…
