After absorbing the solvent the cool mineral oil is heated and then the solvent is steam stripped out of the mineral oil under vacuum The hot stripped mineral oil is then cooled and circulated back for absorption forming a closed loop mineral oil system Optimised Solvent Vapour Absorbing Efficiency Only 5 20 g/m3 of solvent left in In modern base oil refining aromatics are reduced by solvent extraction catalytic hydrotreating or hydrocracking Chronic exposure to poorly refined base oils has the potential to cause skin cancer A chronic mouse dermal bioassay has been the standard test for estimating carcinogenic potential of mineral
