Calculation for the dissolved quantities of oil spilled at sea
- 25 Downloads
Laboratory and field experiments on the dissolution of oil showed that the quantity of the dissolved oil component in the seawater depends on its solubility, concentration in the pertroleum, and the environmental conditions. The vertical oil concentration in calm sea decreases exponentially with depth. The vertical diffusion coefficients and dissolution constants of the N-paraffin from C12 to C21, total iso-paraffin, cycle-paraffin and aromatic components in calm sea were calculated, and the oil dissolution into seawater was determined to be about 0.52% in 48 h for No. 0 light diesel oil.
