The gelling of waxy crudes and the deposition of wax on the inner walls of subsea crude oil pipelines present a costly problem in the production and transportation of oil. The objective of this work is to investigate the correlation between wax content and wax texture by understanding the mechanism and kinetics of the wax crystallization in accordance to A vrami theory. Another is to understand the texture of wax by using Leatherhead Food Research Association Texture Analyzer. The scopes of study for this project involve investigating of the effect of parameters such as temperature, wax composition and organic solvent variance. There will be two different types of solvents and these two will be mixed at three different weight percentages to assume several different oil models which will be tested on two sets of experimentation that is LFRA at three different point of temperature. For LFRA Texture analysis, a generalized texture profile analysis curve is expected to be obtained such as in Instron Universal Testing Machine. From the curve, several texture profile parameter can be identified and a correlation will be. made. It is found that hardness plays a significant role in wax texture and wax content. An absolute correlation can be made from the three scopes of study.
