Rotary Drying: Developing a Process in a Test Setting

Testing not only illustrates proof of process and provides other critical assurances, but it also reveals the parameters necessary to reliably yield consistent results Drying is an integral tool in pretreating and finishing bulk solids, which helps producers to meet…

Commercial debut for sand-based thermal-energy storage

Last month, operation began at Polar Night Energy Oy’s (Tampere, Finland; www.polarnightenergy.com) first commercial sand-based thermal-energy storage system. The thermal storage system, which is located at the Vatajankoski power plant, is now producing low-emission district heating to the city of…

Achieving Balance in Combustion

New hardware combined with monitoring technologies can help optimize combustion now and in the carbon-conscious future Combustion has long been a delicate balancing act. Chemical processors want their combustion systems to be fuel efficient and available for use, while at…

Facts At Your Fingertips: Heat-Transfer Fluid System Venting

Heat transfer fluids (HTFs) provide heating and cooling of process equipment, including reactors, autoclaves, distillation columns, reboilers, mixers and dryers. HTF system designs should provide for effective system venting, both of residual water at startup and of degradation products during…

BASF and MAN Energy Solutions enter into partnership for construction of one of the world’s largest heat pumps in Ludwigshafen

BASF SE (Ludwigshafen) and MAN Energy Solutions SE (Augsburg, both Germany) have entered into a strategic partnership to pursue the construction of an industrial-scale heat pump at the BASF site in Ludwigshafen. This project is intended to make an important…
