LABORATORY BENCH ANALYSIS

Date: January 3, 1991

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 A sample was then withdrawn from each depth, day after day, and analyzed for its water content.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: 

 Depth in inches from Bottom to Top Water % after 1 dayWater % after 3 days  Water % after 5 days
 6" top  0.5 0 0
 5" top 0.5 0  0
 4" top 2.0 0 0
 3" top 20.0 2.5 0
 2" top 40.0  50.0 70.0

Client: Bunker Marine of Virginia, Inc.

Norfolk, VA 23523



Date: 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 After 48 hours, a sample was withdrawn from the middle of the container to check the water level.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 This treated sample was maintained at a temperature of 150°F for four days, with samples withdrawn from different depths at different times to check for water content.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
