Distillation Residue Curve Maps (D-RCM’s) have proven to be an extremely useful graphical tool in the design and operation of both batch and continuous distillation processes. Recently submitted work by the authors has investigated the applications of Residue Curve Maps for membrane permeation systems. Such maps are referred to as M-RCM’s. This paper aims to develop a graphical tool to provide ...

isotactic poly (1-butene), ipbu-1, was synthesized by using a metallocene catalyst. the thermodynamic phase behavior of polymer–organic solvents systems is very important in every polymer application.  in this paper, the solid–liquid equilibrium of ipbu-1 with different organic solvents (1-heptyne, cyclo octane) was studied by a mathematical model. by considering the experiments temperature-mol...

Enhanced volatile organic compounds (VOCs) observations were made on ozone-exceeding days in June 2020 Linyi, China. A total of 69 VOCs collected (1 alkyne, 29 alkanes, 10 alkenes, 14 aromatic hydrocarbons, and 15 oxygenated (OVOCs)). The average concentration (TVOCs) was 36.0 ± 0.66 ppb, the top three components OVOCs, which accounted for 40.75%, 27.02%, 11.30%, respectively. Based positive ma...
