Ceramic packing with low-pressure drops for acid applications
Flexeramic (photo) is a structured packing for acid applications that offers high capacity and efficiency while providing a lower pressure drop compared to other random packing and most trays, says the manufacturer. The structured-packing elements are composed of corrugated sheets of ceramic that are vertically aligned in the packed column, thereby eliminating any horizontal surfaces that may create resistance to fluid flow. This geometric construction reduces the channeling of both liquid and vapor and provides for more effective contact of sulfuric acid and sulfur trioxide gas. Flexeramic structured packing is also ideal for regenerative-thermal-oxidizer (RTO) applications. (for more on RTOs, see p. 49) — Koch Knight LLC, East Canton, Ohio

This thermocouple sensor is optimized for high-purity applications
A new design of thermocouple assembly provides a reliable temperature-monitoring sensor for high-purity fluid systems that traditionally use fluoropolymer components. Designated the TS Series (photo), the assembly has been designed as an alternative to sensors that are fabricated by bonding the thermocouple wires between fluoropolymer-tubing elements, a form of installation often carried out by end users. From analysis of failed parts used in this type of installation, the manufacturer found that the bonding temperature could damage the wires’ insulation. Special attention has therefore been paid to the way the probe fits into the TS Series sensor. The tip itself is also sealed with fluoropolymer for protection and long life, and has minimal dead space and entrapment areas. A TS Series sensor can be specified with either a K- or J-type thermocouple probe. Mounting for the sensor is provided in the form of a compact T-shaped fitting that can be installed into fluid lines to function as a straight union, or a 90-degree elbow joint. The sensor element is installed into one leg of the T assembly, using a standard compression ferrule set. The thermocouple is available for five tubing sizes from 0.25- to 1-in. dia., or in a “jump-size-converter” configuration. — Parker Instrumentation, a division of Parker Hannifin, Tucson, Ariz.
