This company’s Hybrid Still technology (photo) is designed to separate extremely heat-sensitive fine chemicals and other substances. These systems combine the gentle evaporating principle of dynamically mixed and transported wiped thin films with the highly efficient multiple-plate separation capability of fractional columns. Benefits of the technology include short residence time, high vacuum and multiple-plate operation, which provide high purity and yield, with low degradation. Typical applications include purification of edible and essential oils, esters, pharmaceuticals, foods, flavors, fragrances, polymers, extracts, vitamins, waxes, silicones, specialty fine chemicals and many others. Hybrid Still systems are available from 0.1-kg/h bench-top units to pilot-plant and full processing scale, with feedrates up to 1,000 kg/h. The versatile design allows configuration for molecular (short-path) distillation, evaporation or fractionation, plus a choice of glass, 316L stainless steel, Hastelloy or other materials. Complete pilot and production turnkey skid-mounted systems are available, and partial systems and components are also offered. — Pope Scientific Inc., Saukville, Wisc.
