Today’s chemical processors must cope with rising labor costs, increasing global competition, escalating fuel costs and more-stringent safety and environmental regulations. To improve productivity and reduce costs in today’s competitive environment, many facilities are operating leaner than even before. And,…
The Pluto mini-desublimator is used to separate substances in applications such as for tank breathing, thereby reducing emissions to the environment, for recovering raw materials or for protection of downstream vacuum generators. Gas comes in contact with cooled lamellae in…
The RediHeat instantaneous water heater can produce hot water instrantly within ±4F of the set temperature under widely varying demands. Designed with a unique feed-forward temperature control system, the RediHeat is suited to hot-water applications where tight temperature control and…
The new GEMÜ 505 (hand-operated; photo) and 555 (pneumatic) angle seat valves were developed for pure steam shutoff valves, and are available in nominal sizes from DN 8 to DN 80. The valves provide an alternative to the valve types…
Compared with the use of hotplate stirrers or heating mantles, the Stem RS, Stem Omni and Stem Integrity Reaction Stations can reduce energy costs by as much as 90%, says the manufacturer. Equipped for parallel synthesis, these “lab-in-a-box” alternatives to…
Corrections: From the October 2012 Letters page: This original article, which appeared in the print edition of Chemical Engineering (September 2012), had two errors: Equation (19) should read D = log (TH)-0.4, and Table 2 was missing decimal points in…
The main function of the expansion tank in a heat-transfer system is to allow space for the heat-transfer fluid to expand as it is heated. A properly designed, installed and maintained expansion tank will support longer fluid and equipment life,…
The P46S steam trap is the newest model in this company’s PowerDyne product line. The design is said to optimize durability, energy efficiency and reliability. The design of the P46S features a high-tolerance, mirror-finish disc that provides a steam-tight seal,…
The Iceman SM Series is a line of high-efficiency chillers available in capacities from 5 to 15 hp. Iceman chillers utilize Copeland Scroll Digital compressors, which are capable of providing variable-capacity output from 10 to 100% by axially separating internal…
The FFB-8 is a precision fluidized bath with exceptional stability and uniformity for temperature sensor calibration and heat-treatment processes. It offers a built-in dust extraction and collection system, as well as a wide operating range (122–1,292°F) and PID (proportional integral,…
