VTA A new film evaporator is constructed in glass to allow the operator the ability to see the process. With a 70-mm I.D., the evaporator can be configured with a rigid evaporator rotor or a drying rotor. It can be…
Precisive The OXS Series Optical Gas Monitors use tunable filter spectroscopy to measure gas flow components in the ppm to percent range (3100 Series) as well as sub-ppm concentrations (4100 Series). The process monitors are automated, and provide realtime scanning…
FlexFlo filter housings accept filter cartidges from any manufacturer and feature an interchangeable filter basket. Adaptable to inside-out or outside-in flows, the standard filter housings have diameters ranging from 4 to 36 in. The housings allow process engineers and purchasing…
The FL Series recirculating coolers offer 20 kW of cooling capacity with a pump supplying 80 L/min at pressures up to 87 psi. The temperature control instruments feature intuitive operation, wide operating temperature range, rapid cool-down times and a small…
A recently introduced technology for manufacturing tantalum surface alloys offers an affordable solution for processes involving hot acids and other highly corrosive materials. The corrosion-resistant alloy can be applied to valves, fittings, instrumentation and other custom products. The process of…
Foams based on corn starch may one day be substituted for polystyrene foams through technology being developed by the Agricultural Research Service (ARS, Beltsville, Md.; http://www.ars.usda.gov). The ARS Western Regional Research Center (Albany, Calif.) is working on two processes. One…
Retarded polymerization A latent-acid catalyst that can be added to highly reactive pre-polymer resins enabling them to be stored for at least three months prior to controlled polymerization at 120°C has been commercialized by Bac2 (Southampton, U.K.; http://www.bac2.co.uk). Alternative catalysts…
Compressed gas cylinders are widely used in research, pilot plant, laboratory and small-scale manufacturing and processing operations as a way to provide a convenient, economical and safe source of high-pressure gases for various applications. These gases can be inert, flammable,…
Corrosion is estimated to account for a significant portion — 8–10% — of total annual-plant-capital expenditures for the chemical process industries. To avoid it, engineers can consider corrosion-resistant plastics for process piping and storage vessels. Thermoplastics are generally resistant to…
Thermal mass flowmeters provide advantages over other options for metering the consumption of natural gas by individual combustion units throughout the facility With today’s increased emphasis on strategic energy management, many throughout the chemical process industries (CPI) and elsewhere are…
