- W2361485655 abstract "In manufacturing commercial petroleum sulfonate KPS in Karamay, the unsulfonated residual oil (RO) is treated into commercial white oil. Two problems are encountered: low total yield of KPS+RO(73%) and poor quality of RO. The technologic process of sulfonation of the starting oil(a petroleum fraction) by gaseous SO 3 is optimized on a laboratory installation and the optimal technology is selected as follows: sulfonation temperature 35-40℃, sulfonation time 5 hrs, mass concentration of SO 3 in mixture with air 25-40 g/L, settlement time 2 hrs, and secondary sulfonation of unreacted oil. By using this two step sulfonation procedure the acid sludge creation is much decreased, the quality of RO improved and the total yield of KPS+RO increased to 81%. The product of secondary sulfonation contains much more inorganic salts and this is reasoned. The laboratory samples synthesized by the optimized sulfonation technology(KPS 45, KPS 59) have similar surface activity, emulsifying and foaming capacties and slighty better salt tolerencies(18 000 mg/L for Na + and 500 mg/L for Ca 2+ ) in contrast with commercial KPS. The value of CMC is 0.1 g/L for KPS 59. The value of HLB is 13.9 for KPS 45." @default.
