Strategies in Petrochemical Processes Part-II: Sulphur Multi Desorption-Unit for Sweeting of the Peruvian Oil

Abstract

Sulphur contained in crude oil and processed by Petrochemical
Industry can be represent a seriously environmental problem.
Crudes containing a high percent of impurities, such as Sulfur
compounds, are less desirable than low-sulfur crudes because of
their corrosivity and the extra treating cost, increasing production
costs. Sulfur in crude oils is mainly present in the form of
organosulfur compounds (Mercaptans, Thiophene). Hydrogen
sulfide (H2S) is the important inorganic sulfur compound found
in crude oil. Sour crudes contain a high percentage of Hydrogen
Sulfide
