The presence of organosulphur compounds in middle distillate fuels not only leads to air pollution, but they are also a poison to catalytic converters, soot traps and other harmful emission control technologies. A method has been developed for purification of sulphur compounds from diesel fraction from atmospheric distillation by extraction with N-methyl pyrrolidone, furfural and diethylene glycol. The experiment processes at different duration (from 90 to 360 min) and ratio of gas oil fraction:solvent (1:1 and 1:2) show that these methods could be used to reduce the sulphur content in diesel fractions more than twice. The best result was obtained with N-methyl pyrrolidone. The activity coefficients of the raffinate and the extract, the selectivity and the product of the selectivity with the square of the activity coefficient of the raffinate for the solvents are calculated and can be used as an indicative criterion for efficiency in the selection of selective solvents and their comparison. It can be concluded that as the amount of solvent and the contact time increase, the values of the coefficients decrease in direct proportion, which indicates a better selectivity of the process.
