| dc.description.abstract | Application of pour point depressants (PPD) in the form of emulsion provides an alternative in overcoming the problem of handling during application in cold climate environment. Incorporation of antifreeze inside these emulsion helps improve its cold flow properties, without sacrificing much of the other properties. This study considers the effect of varying antifreeze agent – ethylene glycol, propylene glycol and glycerol – incorporated inside EVA emulsion; this includes analysis on the aspect of its thermal behavior and stability, as well as the performance of the emulsion as PPD. The result obtained reveals that in terms of lowering freezing temperature and having the best stability during storage, ethylene glycol (EG) system had given the best results; while propylene glycol (PG) had later comes first in vitrification performance. On the occurrence of selecting the most suitable antifreeze for the emulsion system, the vitrification performance had been a factor to be compromised in event of deciding on EG system; this decision was made due to the fact that EG system offers an adequate performance in vitrification efficiency, although it is not as excellent as the one portrayed in PG system. Aside from this, it had also been proven that the variation of antifreeze agent inside the PPD emulsion does not affect its pour point reduction performance; due to the fact that the polymer used inside each system was the same for all emulsion. | en_US |
