Advanced Polymer Recycling

Polymers like polyethylene, polypropylene, polyvinyl chloride and polyester have become ubiquitous in manufacturing. The properties of polymer-based materials that make them so desirable — they are generally cheap to produce and boast high chemical and thermal stability — also make them abundant, disposable and, in many cases, non-degradable. As... More

Mastering the Challenges of Air-Sensitive Materials

While air-sensitive materials may not be a part of every chemical process, certain catalysts, OLED (organic light-emitting diode) applications, inert gas welding, lithium-ion battery applications and other chemical processes do, indeed, require the inclusion of air-sensitive materials. And, when such materials are present at either research or... More

Protecting Against Compressor Pulsations

Pressure variations resulting from the oscillatory flow patterns found in positive-displacement machinery, especially reciprocating compressors, are referred to as “pulsations.” Found in both liquid- and gas-handling systems, pulsations are a common phenomenon in the chemical processing industries (CPI). Operational problems associated with... More

Bio-Based Chemicals Get Real

With bio-based chemical production growing, and several newer companies ready to enter commercial production, indications are that biologically derived chemicals will be an increasing force in the petrochemicals market. But bio-based chemical producers must confront the bottom-line requirements of product performance and cost, rather than riding their... More
