Análisis hecho para el Sr. H Negron de la compania HPP en Puerto Rico...al producto HPP-621 para tratamiento de bunker-c.

1. HPP-621 Testing in Bunker C
The following test performed is intended to determine how effective the addition of the additive HPP-
621 to bunker-c. The test performed by trained personnel was “Total Ash” Determination of Sample, a
test that determines the effect of different concentrations of additive with bunker-c. A second test was
made collecting the fumes during the first test and makes a simple GC-FID determination to measure
intensity of peaks.
Equipment
Analytical balance, Platinum Crucible, Bunsen Burner, Desiccators, Muffle Furnace, Gas
Chromatographer Equipped with a Flame Ionization Detector
Reagents
Bunker-C Fuel, HPP-621 Additive
Procedure and Results Analysis
4 samples were prepared for testing 1) Bunker-C as is, 2) Bunker-C with
HPP-621 at 480ppm, 3) Bunker-C with HPP-621 at 504ppm and 4)Bunker-C
with HPP-621 at 528 ppm. The required amount of additive per sample of
bunker-c is as follow:
Concentration (ppm) HPP-621/5oz Bunker-C
480 14.0mL
504 14.6mL
528 15.4mL
Higher concentration samples were prepared following the ratio of the
additive instructions (12oz of additive/180 gal) the other concentrations
were prepared. The 4 samples were placed in Glass Bottles and Hand
shaken for few minutes.

2. After sample preparation 1g of each sample was placed into separated platinum crucibles to incinerate
them, fumes generated during the burning process were collected to inject them into the GC-FID. During
test some characteristics were observed.
Bunker-C
(as is)
During Ignition After Ignition w/burner
Observation: Dense brown fumes were observed during ignition of sample (bunker-c, as is). The entire
residue stays in the inner walls of the crucible. After ignition of sample into the Muffle Furnace @ 700 C
a light brown residue stays in the bottom of crucible. The sample was consumed almost totally.
- Fumes were collected for injection into
the GC-FID for peaks intensity analysis.

3. Bunker-C w/HPP-621
@ 480ppm
During Ignition After Ignition w/burner
Observation: Sample was consumed very fast. Residues on inner walls were less but a piece of residue
“carbon-like” remained in the bottom of the crucible. After ignited into the Muffle Furnace @ 700 C an
orange residue remained in the bottom of the crucible.
After Ignition w/burner
These characteristics: less fumes, fast ignition, orange residue after total ignition; increase with the
addition of the additive at different concentration.

Chromatograms and results show a clear view of the positive effects HPP-621, additive imparts into
bunker-c fuel oil. It takes the impurities of the bunker-c fuel oil; toxic emissions, and reduces them in the
combustion chamber. As seen in the results of Total Ash Determination, total ash percent increases as
the concentration of the additive increases. When peak areas of the GC Fumes Chromatograms are
observed it can be noticed that the intensity of the first two peaks decreases. It is concluded that the
additive effectively traps dangerous components normally released as toxic emissions due to the
combustion of bunker-c fuel oil.
