WebThe reason for hazy appearance is due to the precipitation of dissolved waxes. The presence of wax makes the oil appear cloudy at room temperature. The oil normally becomes cloudy in 5–6 h but with proper dewaxing the oil remains clear after 24h of storage at 0˚C. Dewaxing is carried out by chilling the oil up to 10-15°C into the crystallizers. WebIsomerisation dewaxing catalysts isomerise n-paraffins to iso-paraffins, thereby improving cold flow properties while maintaining molecules in the diesel boiling range. When only moderate cold flow improvement is required in trim dewaxing, either catalytic solution can provide comparable performance.
