THE STUDY ON THE NEW TECHNIQUE FOR MANUFACTURING HIGH MELTING-POINT PARAFFIN WAX WITH MIBK

The high melting-point paraffin wax was prepared by taking slack wax as feed and MIBK as single solvent for deoiling. The effects of the solvent ratio, the first dilution temperature and deoiling temperature on the slack wax deoiling were examined. The results showed that, smaller solvent ratio was better when it could meet the requirements of fully dissolving the oil component in the feedstock at the deoiling temperature and good quality filtering; Lower deoiling temperature was more attractive under the qualified oil content, melting point and penetration of the deoiled wax. The semi-refined paraffin wax and fully refined paraffin wax could be prepared at optimum operating conditions.
