Paper Abstract

Light attenuation coefficient (LAC) of crude oil/sea water emulsion was investigated. It was measured using a spectrometer and calculated based on the Mie scattering theory. The emulsion was prepared in laboratory conditions: in two different temperatures (6.7 degree(s)C and 19.3 degree(s)C) and in two different light conditions (in the dark and exposed to light of intensity L equals 500 W/m2). Then the emulsion was stored in temperature T equals 1.3 degree(s)C or in T equals 15.4 degree(s)C and in the dark or exposed to light for 28 days. LAC obtained from model (LAC-M) and LAC obtained from specord (LAC-S) are compatible for fresh emulsion, stored no longer than 3 days. The difference between LAC-M and LAC-S, mainly in the short waves range, increase in time quicker for emulsion stored in a higher temperature than in a lower one or exposed to light than for emulsion stored in the dark.
