This study explains the use of X-Ray CT (computerized tomography) as an alternative tool for cloud point determination of crude oils and dark fuel oils by showing the results for artificially prepared transparent oils. The technique is fully computerized and data gathering and analysis are achieved by taking the advantage of the processing of the CT images. In the study, the cloud points of diesel oil samples containing 5%, 10% and 15% additional wax were determined with this new technique. Results show that the cloud points determined with this technique and the standardized ASTM D-3117 method are very close. This encourages the use of the proposed technique to determine the cloud point of transparent distillate fuels and dark fuel oils and crude oils, whose cloud points can not be determined easily and accurately.
