Abstract: The characteristics of South Pars condensate and the distribution of sulfur containing compounds in its light ends were investigated. Test results show that South Pars condensate belongs to sweet paraffinic base crude oil having low density and low impurity content, yet high in mercaptan content. The corrosion behavior of this condensate and its distillates was studied by copper strip test and high temperature autoclave strip test. Based on the test results, it can be seen that the corrosion of South Pars condensate at low temperature is not significant, but attention should be paid to the corrosion behavior of this condensate and its diesel distillate at high temperature (300 ℃).

Key words: South Pars, condensate, sulfur, mercaptan, corrosion
