Chemical process industries (CPI) facilities often present a number of potential respiratory hazards, including airborne particles, toxic chemicals and low-oxygen environments, that may require the use of respiratory personal-protective equipment (PPE). This reference outlines the major categories for respiratory protection…
The maintenance-free RSK swing check valves (photo) offer a high functional reliability because a tight shut-off is ensured by a rubber-lined valve disc without rotating parts and without extensions through the body wall. Because all wetted parts are rubber-lined, they…
Condition monitoring for predictive maintenance (photo) is a drive solution that focuses on status-oriented maintenance rather than traditional time-based maintenance. Status and drive data are recorded periodically or continuously via the programmable logic controller (PLC) output parameters and can be…
This company has introduced a range of ultra-low profile bolt-load washers that is ideal for bolt-load and tensioner tool calibration. Called TensionDisc (photo), the washers are specially designed load sensors that monitor bolt loads in bolted joint assemblies. A simple…
Corrosion under insulation (CUI) remains a persistent challenge at chemical process industries facilities, but the issue is receiving renewed attention amid a host of technologies, materials and methodologies for detection and prevention of CUI Corrosion of process equipment, piping and…
The MDM900 mill-discharge slurry pump (photo) is the latest addition to this company’s flagship Mill Discharge (MD) Pump Series. The MDM900 is designed for heavy-duty use in concentrator plants, where capacity and wear-resistance are essential. The MDM900 is an all-metal,…
Evaporation and crystallization technologies have the ability to create advantages for pulping facilities by improving operational efficiency and reducing waste, while simultaneously producing high-value product streams The emergence of new products and markets is driving a global renaissance of the…
Lysine (Figure 1) is an α-amino acid used in the biosynthesis of proteins. The compound contains an amino group and a carboxylic acid group. Under biological conditions, the amino group is protonated (–NH3+) and the carboxylic acid group is deprotonated…
Many factors impact the performance of synthetic filtration media, from thread and weave styles to drainage and coverage considerations Under the broad umbrella of filter media, there are many synthetic media materials, including woven filter cloths, woven and non-woven fabric…
When a pump operates inefficiently, or fails all together, the challenge is to make the most economical decision on how to remedy the situation. Some guidance is provided here Centrifugal pumps are widely used throughout the chemical process industries (CPI).…
