The new Semistat series of thermoelectric process thermostats (photo) are used to control temperature in etching processes in the semiconductor industry. Semistat S 1200 is an entry-level device that offers a small footprint with a cooling output of 1.2 kW…
The efficiency and service life of pumps can be greatly extended by following the manufacturer’s installation recommendation for pipe straight run entering the pump. When cramped pump houses or restricted pipe runs make this impractical and costly, this company offers…
The new VPM3000 Series of universal input displays (photo) with transmitter and alarm capabilities combines the digital indicator function of a panel meter with optional signal conditioning for 4–20-mA transmitter output and alarm trip solid-state relays. The devices are able…
The next-generation VCM-3 condition-monitoring platform (photo) is designed to increase the uptime and reduce overall lifecycle costs of pumps, fans, motors, gearboxes and many other types of machines, while increasing reliability. The field-proven VCM-3 is a 12-channel data-acquisition hub for…
Ensuring optimal screening processes and productivity is vital for a vast range of processing needs. This company recently expanded its 10,000-ft2 Materials Testing Laboratory (photo), which conducts advanced screening testing. The lab’s experts recently worked on a full-scale material-recovery test…
The TDLS8100 probe-type tunable diode-laser-spectrometer (TLDS) realtime gas analyzer (photo) makes quick and accurate in situ gas-concentration measurements, eliminating the requirement for sampling and conditioning components in industrial process-heating applications. These capabilities support safety improvements, emissions reductions, optimization of fuel…
The newly redesigned RS-02 high-shear pilot-scale mixer (photo) is well suited for pilot plants and small-scale production, including product development, formula optimization and trial mixtures. The RS-02 redesign includes a mobile lift stand with a wider base for added stability…
This column is based on “Orthophthalic Unsaturated Polyester Production Process – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/unsaturated-polyester-resin-production-cost. Unsaturated polyester resins (UPRs) are solutions of unsaturated polyesters in co-polymerizable monomers, which undergo cross-linkage to…
In order to recycle spent acids from different applications, a design approach based on different process modules gives operators the flexibility needed to handle different contaminants Spent or waste acids (SA) containing sulfuric or nitric acid are a byproduct of…
This overview of a number of different methods for handling spent acids will help operators select the technology most suited for a given application The most common pickling, leaching and passivation acids are the mineral acids: sulfuric, hydrochloric and nitric.…
