ABSTRACT
Kuwait heavy gas oil has been dewaxed using five different solvents: methyl ethyl ketone, methylene chloride, ethylene chloride, methyl isobutyl ketone and methyl isopropyl ketone. The dewaxing temperatures were in the range of (0°C to - 2O°C). The most important factors which affected the properties of dewaxed oil were: wax crystallization temperature, dewaxing temperature and the waxy raffinate properties. Empirical correlations were developed to predict the properties of the dewaxed oil and wax produced in terms of these factors.
