Novel and Conventional Approaches to Sterilization
The techniques used for sterilization have a major impact on product quality and safety where pristine processing is needed The inactivation and elimination of bacteria are pressing issues in the chemical process industries (CPI) where high-purity conditions are needed. High…
Solids Processing: Prevent Caking and Unintended Agglomeration
Learn what causes caking and how testing methods can help identify critical parameters for controlling it Caking occurs when an easy-flowing powder becomes cohesive after storage or transport, forming agglomerates comprised of individual particles that are bonded together. As a…
Facts at your Fingertips: Vacuum Pumps
Vacuum is any system of reduced pressure, relative to local (typically atmospheric) pressure. Achieved with a pump, vacuum systems are commonly used to: Remove excess air and its constituents Remove excess reactants or unwanted byproducts Reduce the boiling point Dry…
Cover Story Part 1: Level Measurement Technologies For the CPI
Plant performance and safety are key issues for the chemical process industries (CPI) and level measurement plays a crucial role in both. Level measurement helps maintain material inventory at economic quantities, improves product quality and ensures a smooth continuous…
Cover Story Part 2: Liquid-Level Measurement Options In the CPI
Many types of industrial processes utilize liquid level sensors to provide the information needed to monitor and control a process. This enables the design parameters to be maintained in order to produce the end product at the desired level of…
Feature Report: Incorporate Floating Solids Into Liquids
The incorporation of floating solids into liquids is a common challenge throughout the chemical process industries (CPI) in operations ranging from polymerization reactions to fermentation processes and water treatment. Yet, it has received much less attention in comparison to processes…
Closed Liquid Dispensing: Secure Container Contents While Reducing Risk
With the increasing demand for security, drums and other liquid vessels that contain valuable or hazardous liquids can be retrofitted with a simple dispensing-valve system that virtually eliminates leakage and ensures product integrity Although the storage, security, handling and dispensing…
Finding the Right Gloves To Fit the Application
Workers in the chemical process industries (CPI) would certainly benefit from the "perfect" glove that would be thick enough for thermal insulation, thin enough to promote dexterity and tough enough to protect workers from cuts and abrasion. The glove would…
