Abstract:The wax present in petroleum sludge, generated by the refinery and at the crude production sites, consists of paraffin hydrocarbons (C18 -C36) known as paraffin wax and naphthenic hydrocarbons (C30 -C60). The present study is aimed at the recovery of wax from the petroleum oily sludge by microwave assisted solvent extraction using Toluene/MEK mixture and subsequently de-crystallizing the wax. The process variables affecting the microwave assisted solvent extraction is optimized for recovery of wax. The simulta… Show more
