Steam Handling

Sodium-ion monitoring can prevent steam-turbine corrosion Studies have shown that sodium is one of the most significant contributors to corrosion within turbines, and that such corrosion leads to cracking, embrittlement and ultimately, turbine failure. The Orion Ionplus 2111LL low-level sodium…

…or by steam distillation

Another process that removes up to 90% of the TCA from cork (see item above) was recently launched by Cork Supply USA (Benica, Calif.; edlinks.chemengonline.com/5828-534). The Cork Supply Group in Portugal has been testing the process for over three years…

Metals-‘free’ H3PO4 is now available off the shelf

A new phosphoric acid that contains less than 100 parts per billion of 30 different metal ions is now commercially available from Febex S.A. (Box, Switzerland; edlinks.chemengonline.com/5828-539), the phosphorous specialties subsidiary of CECA Arkema Group (Paris). The new grade of…

This flowmeter now has a FF massflow-function block

Last month, Emerson Process Management (St. Louis, Mo.; edlinks.chemengonline.com/5828-540) launched the Rosemount 3095 MultiVariable transmitter with FOUNDATION Fieldbus (FF) technology and fully-compensated mass-flow functionality. Said to be a first for the process industries, this extension to the Rosemount 3095 platform…

Integrating CFD & DEM

Fluent. Inc. (Lebanon, N.H.; edlinks.chemengonline.com/5828-541) has entered a partnership with DEM Solutions (Edinburgh, U.K.; edlinks.chemengonline.com/5828-542) to complement Fluent’s multiphase computational fluid dynamics (CFD) models with discrete-element-modeling (DEM) capabilities. DEM Solution’s EDEM software enables engineers to simulate the behavior of particuate…

A new metal nitride

Using a diamond anvil cell to create high (up to 50 GPa) pressures, and a laser to create high (up to 2,000 K) temperatures, researchers from Lawrence Livermore National Laboratory (LLNL; Calif.; edlinks.chemengonline.com/5828-543), the Carnegie Inst. of Washington, and the…

Combustion guidelines

Last month, the Commission on Air Pollution Prevention of the VDI and DIN Standards Committee (Düsseldorf, Germany; edlinks.chemengonline.com/5828-544) published a new guideline (VDI 2442), which provides specific information on the design, construction and operation of waste-gas cleaning plants using thermal…

3D nanostructures

By combining a high-resolution scanning electron microscope and an ion-beam microscope into a single device, researchers at the Max Plank Institute for Iron Research (Düsseldorf, Germany; edlinks.chemengonline.com/5828-545) are able to “see” the inner structure of nanomaterials, biological matter, and high-performance…

Distillation: How to Specify & Install Cartridge Trays

Cartridge trays, defined below, can be the perfect hardware solution for distillation columns that are less than 3 feet (0.9m) in diameter and have a unique need for trays. Packing is usually the preferred choice for small-diameter columns, but there…

A worthwhile trek back to the sandbox

For any of us who have kept up in recent years with the business news (happenings at Enron and some major Wall Street firms, say), it seems safe to assume that, nowadays at least, ethical behavior and personal honesty are…
