CONSTITUTION:High boiling point residual material such as chloroform, 1,2- dichlorethane discharged from vinyl chloride monomer production process undergoes vacuum distillation under a reduced pressure between 0.1mmHg-760mmHg, preferably 0.1-200mmHg to remove contained tar materials. The distillate is ...
Both of the methods involve heat treatment under vacuum or under flow of a gas. However, for the polycondensation reaction to efficiently proceed, these methods require not only very high temperatures, although not higher than the melting point, but also treatment for a long period of time. ...

constants at high temperatures for the 12 common CVOCs measured in this study, it will be possible to more accurately model subsurface remediation processes that operate near the boiling point of water.;The laboratory experiment was simulated with a 2-D multiphase numerical model using the TMVOC ...
