Abstract

Generally, large amounts of DOP(Di-Octyl Phthalate) chemicals are used as plasticizers in PVC compound manufacturing processes. However, it is very important to collect DOP species immediately from a workplace in order to protect worker's heath and recover them. To accomplish these objectives, we need to understand the droplet formation and growth mechanisms of DOP species. In this study, two important parameters such as temperature gradient and residence time were considered to clarify these mechanisms. We found that residence time is very critical to determine the droplet size distribution of DOP, whereas temperature gradient in general operating conditions(less than $-6.8^{\circ}C/cm$) is negligible.
