Chemicals Based on the Light Fraction of Natural Mercaptans/ K.D. Korenev, V.I. Latyuk and V.I. Kelarev [editors]. Nova Science Publishers, Inc., New York, 2006. - 212 p. ISBN-13: 978-1-60021-650-3 (hardcover), ISBN-10: 1-60021-650-1 (hardcover)

     Many major oil-and-gas fields in USA, Canada, Russia and other countries keep sulfur-, oxygen- and nitrogen-containing chemicals along with general hydrocarbon mass. These impurities complicate the processing of natural raw hydrocarbons material to fuels and chemicals contaminating them and decreasing their consuming properties. In particular, it is generally known that sulfur-containing impurities lower the stability of hydrocarbon fuels towards oxidation. At the same time these impurities are the cause of corrosive action of the fuels.
     Along with other sulfur-containing chemicals, mercaptans (sulfur-substituted analogues of alcohols) are often present at sulfurous oils and gas condensates in noticeable amount. Mercaptans could be extracted with water solutions of sodium and potassium hydroxides. The amount of natural mercaptans that can be potentially isolated this way is dozens of thousand tones per year. The example is the processing of gas condensate from Orenburg (Russia), Crossfield and Line Creek (Canada), Lac (France) and many other fields. However the qualified way of utilization of these mercaptans is not found so far. The most common way today is to burn them with formation of noxious sulfur oxides. Moreover, limited amount of mercaptans is used as odorant (substance possessing strong objectionable odor) for fuel gas.
     The present book describes scientific basis for isolation and possible utilization of the light fraction (C2-C5) of mercaptans, containing in gas condensate from Orenburg (Russia).
