VolSolv™ (Proprietary Process)
VolSolv™ is Volantis Group's trademarked line of chemical processes engineered to efficiently remove fouling deposits from industrial equipment during preoperational cleaning.
Traditionally, cleaning operations require three separate chemical treatments to:
- Remove light oils and protective coatings applied during manufacturing or construction.
- Dissolve mill scale.
- Eliminate iron oxides and corrosion deposits formed on steel surfaces.
These conventional methods often demand three different solutions, multiple rinses, and seven to eight volumes of water, with operations stretching over a week to complete.
The VolSolv™ process streamlines this by using a single chemical volume to achieve the same — or superior — results. This significantly reduces cleaning time, water consumption, and overall project duration, making VolSolv™ a more sustainable, efficient, and cost-effective alternative for industrial pre-commissioning.
Following mill scale removal, the solution is converted to a neutralization/passivation treatment by raising the pH to approximately 9 and adding a non-chemistry-based oxidizer. This final stage ensures internal surfaces are properly passivated and prepared for operation.
Water cycle passivation
Where feedwater, condensate and HRSG systems are in scope, VolSolv™ follows the flush with a passivation of the water cycle. Passivation chemistry is added to the demineralized water used to fill the condensate, feedwater and HRSG systems, protecting the passive layer of magnetite on the steam cycle surfaces applied during chemical cleaning and consistent with the normal desired operational condition of the metal surfaces.
Summary of process advantages:
- Potential elimination of the cost of traditional chemical cleaning.
- Vastly reduced water consumed when compared to conventional chemical cleaning.
- Reduced or eliminated waste product, and environmentally friendly.
- Greatly reduced disruption to project schedule.
- Short duration, providing schedule savings.
- Complies with all major vendor requirements for initial chemical degreasing and passivation of new HRSGs.
VolSolv™ is applied within VGI's fluid system flushing and debris removal scope.
