Resumen

The crude oil in water emulsions have been used to produce and to transport heavy hydrocarbons. More stability and less viscosity than the emulsions prepared with an only surfactant was obtained for the crude oil in water emulsions prepared with non-ionic and anionic surfactant mixtures, in previous studies. The stability of these emulsions could be increased, adding short chain amines. In this work, the effect of aliphatic short chain amines in the stability and the rheological properties of heavy crude oil in water emulsions, prepared at crude oil/water relationship of 70/30, is discussed. Polyethoxylated non-ionic surfactants were used, individually or in a mixture with an anionic surfactant of aryl benzene sulfonate type. Aliphatic short chain amines of 2, 4 and 6 atoms of carbon were used as co-surfactants, so much of lineal chain and ramified chain. The results showed that the primary amines of lineal chain produce more stable emulsions and with more viscosity that the emulsions prepared with secondary or tertiary amines of the same number of atoms of carbon. It was concluded that aliphatic short chain amines are excellent cosurfactants, because they stabilize micelles formed inside the system surfactant-watercrude oil.
