Abstract

Determination of the composition of the DCO is done by means of centrifugation, where oil samples taken from COT (Crude Oil Tank) was added centrifuge, then do centrifugation or centrifugal force for 4 minutes to separate the oil, emulsion and sludge. Calculation of percentage composition of DCO done in order to determine loss (oil losses) at the time of sampling done. Thus obtained the data from sampling conducted over four consecutive days, on 06-02-2016 is an oil 36,75% ; emulsion 3,70% ; sludge 59,55%, on 08-02-2016 is oil 36,10% ; emulsion 3,57% ; sludge 60,71%, on 09-02-2016 is oil 36,01% ; emulsion 3,93% ; sludge 69,87%, and on 10-02-2016 is an oil 36,26% ; emulsion 3,43% ; sludge 60,31%. Where the DCO percentage gained is still in standard conditions or stable condition where the standard of the company 34-38%, so it is still eligible from the companies.
