ChemShow 2009 Preview

ChemShow 2009 will be held November 17-19 at the Jacob Javits Convention Center in New York.  “Processing Solutions for a Changing Marketplace,” the show will showcase over 300 exhibitors and anticipates more than 10,000 professional attendees.

ChemShow 2009 will feature a technology conference and symposium on nanoscale materials and “green” technology. Organizers say the focal point of the symposium will be bridging the gap between science, technology and commercialization. Created for the ChemShow by Innovative Research and Products (iRAP; Stamford, Conn.), the “Nano and Green Conference & Symposium” will explore the impact of nanotechnology on environmentally friendly processing. The conference will focus on colloids and surface modifications that benefit nanotechnology applications, nanoparticle synthesis and nano-bio convergence and their emerging technologies and markets.

Aside from the product exhibition and symposium, the show features a host of educational sessions. Chemical Engineering will present a two-day educational program (see pp. 30-31).The Valve Manufacturers Association (VMA; Washington, D.C.) will present sessions on the use of valves and actuators in the chemical process industries (CPI). A number of sessions are offered as part of AIChE Day (American Institute of Chemical Engineers; New York) at the Chem Show. Among the offerings is a tutorial session on the fundamentals of powder flow technology, which will seek to provide insight into common flow problems of solids. Other AIChE sessions include mixing basics, troubleshooting pneumatic conveying systems, sustainability practices, process safety and others. Additional information about the show can be found at

A better way to make pellets
of PS and POM


The WRG range of water-ring pelletizers (photo) for making pellets of polystyrene (PS) and polyoxymethylene (POM) has the advantage that the cooling and conveying medium (water) does not come into direct contact with the die plate. The rotating knives cut the extruded strands of melts into pellets. Centrifugal action of the knives sends the still-hot pellets into the rotating water ring, which cools them and conveys them out of the pelletizer hoods. Favorable operating costs result from: the low energy requirement for the die plate and the rotor drive; the negligible wear on the knives and the die plate; and the simple and rapid startup process. A WRG 320 has been delivering 5,000 kg/h PS pellets for two years, and a 9,000 kg/h unit has recently been delivered. — Coperion GmbH, Stuttgart, Germany
