Crystallization fractionation technology for paraffin-based phase change materials production
New method of high quality paraffin-based phase change materials (PPCM) production with narrow fractional composition based on crystallization fractionation (CF) technology is described in the article. PPCM global market research results demonstrating constantly growing demand for this production are introduced. Comparison of CF-technology with well-known high quality PPCM production process based on vacuum rectification is carried out, which shows advantages of the proposed technology. CF-technology laboratory studies data are provided. As a result of these studies, dependencies of obtained products quality from technological regime main parameters influence are identified and the representative laboratory PPCM sample for the subsequent tests is received. Thermo-physical properties comparison results of this PPCM sample and the best worldwide commercial PPCM analog are also presented. These data prove that PPCM sample obtained with CF-technology has superiority over foreign competitor.
