Documented Field Application Details
System cleaned
Project / Cleanup Context
The recovered oil system had been used in an MSRC test with No. 6 and No. 2 fuel oil and emulsion chemicals.
PES Product Use
PES-51 was used to clean the four 1,000-barrel tanks, piping, and oil/water separators.
Reported Field Note
The recovered oil system components were decontaminated after the test.
Additional Notes
The case history specifically identifies the full system scope.
Application methods
Project / Cleanup Context
Fuel oil and emulsion chemical residues were present in the system.
PES Product Use
Pump sprayer, airless sprayer, and circulation of PES-51/oil cleaning solution were used.
Reported Field Note
PES-51 was circulated through the recovered oil system piping.
Additional Notes
This example is especially relevant to piping and recovered oil system cleaning.
Rinse condition
Project / Cleanup Context
Piping required final flushing after PES-51 cleaning.
PES Product Use
The piping was flushed and rinsed with ambient-temperature seawater.
Reported Field Note
The system was rinsed to a sheen-free condition.
Additional Notes
