Carus Solutions for the Oil & Gas Industry
The oil and gas industry faces significant challenges in managing the byproducts of crude oil refining and produced water treatment:
- Pyrophoric Iron Sulfide: Formed during crude oil refining, pyrophoric iron sulfide reacts exothermically when exposed to air, posing risks of fire and toxic gas release during plant turnarounds.
- Produced Water Management: Produced water contains high levels of contaminants like iron, hydrogen sulfide (H₂S), and mercaptans, which cause operational inefficiencies, safety hazards, and environmental compliance issues.
How Carus Can Help
Carus delivers innovative permanganate-based solutions to address these challenges effectively:
Pyrophoric Iron Sulfide Removal:
- Permanganates oxidize pyrophoric iron sulfide to iron sulfate, eliminating risks of exothermic reactions and fires.
- This process controls toxic odors by converting sulfides into odorless sulfates.
Produced Water Treatment:
- Permanganates oxidize soluble iron and manganese into insoluble precipitates for easier removal.
- Odorous and corrosive sulfur compounds like hydrogen sulfide and mercaptans are neutralized through chemical oxidation.
Benefits of Permanganate in Oil & Gas Applications
Carus’ CAIROX® Potassium Permanganate and CARUSOL® Sodium Permanganate offer:
Complete control over pyrophoric iron sulfide.
Lower vessel cleaning costs.
Reduced risks of toxic gas release, fire, or explosion.
Safer working conditions with visual indicators for treatment completion.
No need for pH adjustment or specialized materials of construction.
Environmentally friendly spent solution discharge options.
Applications
- Pyrophoric Iron Removal: Add permanganate as a 0.1–1.0% aqueous solution to process equipment. Monitor solution color (purple to brown) to determine treatment progress.
- Produced Water Treatment: Use permanganate for clarifying and filtering water by oxidizing iron, manganese, and sulfur compounds.
