Sieve Tray Stability Factor Based on Efficiency Data

Using a vast collection of experimental distillation-column data, sieve tray stability, and its influence on efficiency, are explored in terms of several physical and mechanical properties For trayed distillation columns, the concept of tray stability was introduced by the author…

An advanced calibration platform for airflow meters

Flow Detective Plus (photo) is an electronic airflow-meter calibrator designed to measure the flow of air-sampling pumps to within 2% accuracy. It can calibrate within the airflow range of 20 to 5,000 mL/min to ensure correct flow. Compatible with this…

The first digital pressure gage with IO-Link

The MAN-LC (photo) is said to be the only digital pressure gage available with IO-Link. The device includes two configurable outputs that form part of a standard instrument and may be custom-programmed by users as desired. The display screen features…

Improve turbine reliability with this oil-cleaning system

Vartech Industrial System Cleaner (ISC; photo) provides turbine operators with a non-solvent-based solution for removing varnish and sludge in turbine-oil systems. Vartech ISC can be added directly to oil during operation to clean varnish and sludge before a scheduled oil…

Increase efficiency and service life in CVD process control

ParallelPro (photo) is a leveling tool designed for chemical-vapor-deposition (CVD) processes, or any equipment requiring precise parallelism. Equipped with wireless communications and a field-serviceable battery pack, the ParallelPro measures offset distance, parallelism and temperature. Measurements are transmitted via Bluetooth to…

Backwash Tuning for Reliable Sand Filtration

This practical guide provides information on proven backwash-tuning techniques that will improve the reliability and robustness of sand filters in water treatment applications Water is a fundamental part of virtually all plants in the chemical process industries (CPI). Examples of…

Sequencing Batch Reactors for Water Treatment

Sequencing batch reactors (SBRs) are a variation on the activated sludge process in wastewater treatment. This article provides an overview of SBRs, including their history, current use and future outlook Sequencing batch reactors (SBRs) are a type of wastewater treatment…

Clean injection molds using ultrasonic technology

Branson MCX Series cleaners (photo) are ultrasonic systems purpose-built for cleaning plastics injection molds. They feature side-mounted, immersible transducers and powerful immersion heaters that can provide fast and efficient cleaning. Since most plastic injection molds are rectangular, with a lot…

This pipe combines corrosion resistance and durability

DetaPipe (photo) is a new high-performance clad-metal pipe product designed for use in corrosive, high-temperature processing environments. DetaPipe is produced using a proprietary process that joins corrosion-resistant alloys, such as zirconium and titanium, to lower-cost, base metals, such as carbon…
