The VD and VDL drying ovens can dry samples completely without residues, scaling or oxidation, thanks to an innovative control concept. The temperature is controlled over the entire range, without overshooting. The controller also includes a temperature selection limiter, multi-program…
The topic of fouling in heat exchangers has been of increasing interest in recent years, since it is so closely linked to the cost of building and running a chemical plant. It has been reported that fouling costs are about…
The U.S. Energy Information Administration (EIA; Washington, D.C.) recently released the complete version of its Annual Energy Outlook 2011 (AEO2011; www.eia.gov/forecasts/aeo), which includes projections for energy production, consumption, technology and market trends, and the direction they may take in the…
A new Macrowave radio-frequency (RF) drying system provides greater efficiency than conventional web dryers and enables the high-speed drying of water-based patterned glue and coatings at line speeds previously reached only with solvent-based coatings, says the manufacturer. The dryer selectively…
A new, three-ton chiller developed by this company is based on an absorption-cycle process with an aqueous ammonia solution as the working fluid. It is intended for applications requiring smaller or mobile units, such as military electronics cooling, refrigerated transport…
CombustionONE is an integrated solution for managing and controlling combustion-based processes. The system is designed to improve safety and efficiency in fired heaters, dryers, heat exchangers, boilers and other combustion equipment. Featuring this company’s automation technology, CombustionONE promises increased safety,…
Motorists filling up at U.S. gasoline stations these days may think that petroleum refiners are making good profits, but it depends on where the station gets its fuel. The industry is plagued by overcapacity and is concerned about government regulations…
GEA Air Treatment CAIRplus air-handling units for airflow from 3,000 to 23,000 m3/h are now available with adiabatic cooling. These models cool extracted air up to the saturation point. The cold produced by evaporation is then transferred to the supply…
Gas turbines are widely used throughout the chemical process industries (CPI) — especially in petroleum refineries and petrochemical facilities — to provide both mechanical-drive and power-generation capabilities. Presented below are a variety of recommendations related to the selection and arrangement…
GEA PHE Systems The new EcoFlex CDH heat-exchanger frame range features frame plates that have been considerably reduced in thickness. The cross section reduction in the clamping bolts has been compensated for by a greater number of bolts, which in…
