| titleOfInvention | A PROCEDURE FOR OBTAINING PETROLEUM SULPHONATES AND WHITE OILS OF TECHNICAL QUALITY. |
| abstract | A procedure for obtaining sulphonates fromnoil and white oils of technical quality from oilsnused lubricants, together with relatively lower amountsnof asphalts and light hydrocarbons, which includes the stages:n n n n n to)n n n pre-treat the oilnused to avoid the tendency to fouling and corrosion ofnthe teams in stage (b);n n n n n n n b)n n n distill the mixturenpre-treated from stage a), to separate by anwater part, and light hydrocarbons, a fraction ofnboiling point below 150 ° C, a fraction ofngas-oil, fractions of lubricating oils and anresidual asphalt fraction, andn n n n n sulfonate the fractions of lubricating oilsnobtained in b) with sulfur trioxide and subsequently neutralizento obtain technical white oils and petroleum sulphonates. |
