Water-in-Crude oil emulsion stabilized by natural surface active components (such as asphaltene) are one of the major problems in relation to petroleum production.such problems : the corrosion of pipe work pumps production , equipment and downstream overhead distillation columns - the expense of pumping or transporting the water via pipeline or tanker - the problems associated with increased oil viscosity as a consequence of finely dispersed water within crude oil.One of the readily used methods for breaking emulsion is chemical demulsification by surfactants for this reason A new of some...

The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have always been considered to be the first line of defense against corrosion. A great number of scientific studies have been devoted to the subject of corrosion inhibitors.Cationic surfactants represent only 5-6% of the total surfactant production. However they are extremely useful for some specific uses, because of their peculiar properties .They are not good detergents nor foaming agents, and they cannot be mixed in formulations which...
