Technology Profile: Production of EPDM Rubber

Ethylene propylene diene monomer (EPDM) rubber is a terpolymer elastomer derived from ethylene and propylene, along with small amounts of a non-conjugated diene as a third monomer (Figure 1). With a completely saturated polymer backbone, this random elastomeric copolymer exhibits…

Multi-diaphragm dosing pump is virtually maintenance-free

The Chem-Feed CD1 (photo) is engineered to ensure almost no maintenance requirement for the life of the pump. CD1 is suitable for dosing with gas-forming chemicals, such as peracetic acid or sodium hypochlorite. The CD1 Dual Diaphragm Hyperlink Drive Technology…

A filter to recover and recycle valuable battery chemicals

Launched last month, the energy- and water-efficient AC (activated carbon) filter responds to the market’s increasing demand for advanced and sustainable battery-metals processing technologies. The modular AC filtration technology (photo) is designed for smaller side streams of copper and other…

Controlling Particle Characteristics with Agglomeration

Solids-handling processes and downstream process steps can benefit greatly from carefully controlled particle characteristics. Presented here is guidance on how agitation agglomeration techniques can achieve desired particle properties Throughout the diverse sectors of the chemical process industries (CPI), the ability…

Gas Trapping Can Unsettle Distillation Columns

Operational troubleshooting guidance is provided for several scenarios involving trapped non-condensable gases in distillation towers Non-condensable gases are often present in distillation towers, either expectedly or unexpectedly. When they do appear, or when the quantity of non-condensable gases varies from…

Focus on Analyzers

Measure every liquids’ ‘fingerprint’ in real time This company has developed a new radio-wave-based analysis technology that enables continuous monitoring of the state of any liquid, including thick slurries, resins, adhesives, coatings, emulsions, beer, water and more. The Collo Analyzer…
