This company is introducing two new rotary tube furnaces that are suitable for heat treatment; calcination of powders, granules and fibers; pyrolysis; and the recycling and production of rare-earth metals. The FDHK-5-1400/10800/450 model operates at a maximum temperature of 550°C,…
For oil-and-gas and power-generation applications, the RB211 gas-turbine systems have already proven themselves, with more than 700 units now recording over 30 million operating hours. Now, the manufacturer has developed the RB211-Gzero retrofit upgrade, which provides users of industrial RB211-C…
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…
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 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,…
