Samples:

A sample with a high percentage of water emulsified in #6 fuel oil was presented
for de-emulsification tests to evaluate the advisability of employing Alken®
860.



 



Analysis:

The fuel has a high wax content, which solidifies at room temperature (Pour
Point: 110°F). 30% of the water is emulsified (TDS is 15,000 ppm, mostly
chlorides).



 



Application:

Alken® 860 was blended into the fuel, at a dosage of 1 gallon
to 1,000 gallons of oil. The treated sample was maintained at a temperature
of 150°F for five (5) days. A sample was taken from different depths,
at different times to check the water concentration. In order to simulate the water separation in the fuel tank,
we selected a glass jar, which holds a total volume of 1 liter, on which
we marked the depth from the bottom to the top, (0-6"). A sample was
then withdrawn from each depth, day after day, and analyzed for its water
content.





The results are shown in the following table:

February 7, 1991






Samples:

Four fuel oil samples, received on January 29, 1991, were taken from Barge
T/13 on January 25th, and marked as follows:



1-Tank #2 STBD, Top sample

2-Tank #2 STBD, Middle sample

3-Tank #3 STBD, Top sample

4-Tank #3 STBD, Middle sample






Analysis:

The samples are different from the last samples we received from Standard
Tank Cleaning Corp, Bayonne, N.J. They are fluid at room temperature and
possess the odor of gasoline. The water content of these four samples is
as follows:



1-Tank #2, Top 25%

2-Tank #2, Middle 15%

3-Tank #3, Top 12%

4-Tank #3, Middle 20%






Application:

1- One sample from Tank #2-Top, which had 25% water, was heated in an oven
at 150°F, without having added any treatment, as a control. After 48
hours, a sample was withdrawn from the middle of the container to check
the water level. The water content was 20%.






2- Another portion of the same sample was
treated with Alken® 860, at a dosage of 1 gallon to 1,000 gallons
of sample, was then placed in a glass jar (6" high). This treated sample
was maintained at a temperature of 150°F for four days, with samples
withdrawn from different depths at different times to check for water content.






The results are shown in the following table: 









 Depth in inches from Top to Bottom Water % after 2 days Water % after 4 days
 6" 0.0 0.0
 4" 3.0 1.5
 2" 5.0 3.0
 0" Bottom 100 100
