Dispersion of Arabian crude oils in sea water by finasols H. Awad, S. H. Gashlan.

Abstract EN

The efficiencies of 3 commonly used chemical dispersants in Saudi Arabia were tested in the laboratory.

Effects of variations of both ratios of applied dispersants to oil intended to be removed from water surface and stabilization time for the produced oil dispersion were assessed.

The results obtained showed that amongst the tested Finasols-type dispersants, 90% of arabian light crude oil could be removed by the application of a quantity of 10% diluted Finasol-5 corresponding to half of the spreaded crude oil.

In the case of heavy arabian crude oil, the use of either of the three dispersants (Finasols-2, -5 and -7) never produce the removal of more than 60% of the spilled quantity.

This is true when the same conditions are followed as in the case of arabian light.

Meanwhile, by application of Finasol-7 corresponding to 80% of the heavy crude oil, 98% of it could be dispersed after 24 h.
