Oil and Gas Applications for Phosphoric Acid 75%

Scale Removal and Descaling

— Dissolves calcium carbonate, iron oxide, and phosphate mineral scale from production tubing, heat exchangers, separators, and cooling water circuits, restoring flow efficiency and heat transfer performance

Metal Surface Treatment and Passivation

— Removes rust and mill scale from steel pipelines, storage tanks, and process equipment; reacts with iron to form a protective iron phosphate conversion layer that improves adhesion for protective coatings

pH Control in Produced Water Treatment

— Used to adjust and buffer pH in produced water handling systems, injection water circuits, and wastewater treatment operations, optimizing downstream treatment chemistry

Corrosion Inhibitor Formulations

— Serves as an active component in phosphate-based corrosion inhibitor packages formulated for carbon steel pipelines and vessels

Drilling Fluid Additives

— Acts as a pH buffer and dispersant in select water-based drilling fluid systems, helping to stabilize formation clays and improve fluid rheology

Iron Control in Acidizing Treatments

— Incorporated into matrix acidizing and stimulation treatments to chelate dissolved iron and prevent damaging iron hydroxide precipitation in the near-wellbore region

Refinery Catalyst Support

— Used as an acidic catalyst or catalyst support component in certain alkylation and isomerization unit processes within refinery operations

Phosphoric acid is valued across the oil and gas sector for its effectiveness as an acidizing agent, scale inhibitor, and surface treatment chemical:

Handling and Storage in Oil and Gas Environments

Phosphoric acid at 75% concentration is a corrosive mineral acid. Proper handling in field, plant, and refinery settings is critical for personnel safety and equipment integrity.

Personal Protective Equipment (PPE):

  • Chemical-resistant gloves (butyl rubber or neoprene recommended)
  • Safety goggles or face shield
  • Acid-resistant apron or coveralls
  • Chemical-resistant boots in areas of potential splash

Storage Requirements:

  • Store in a cool, dry, well-ventilated area away from direct sunlight
  • Use containers rated for corrosive acids; avoid carbon steel — HDPE, FRP, or 316 stainless steel are appropriate materials
  • Keep containers tightly sealed when not in use to prevent moisture absorption and concentration changes
  • Segregate from strong bases, oxidizers, and reactive metals
  • Maintain secondary containment per EPA and local spill prevention requirements

Regulatory Compliance:

  • Review the SDS before first use and after any lot change
  • Train personnel per OSHA Hazard Communication Standard (29 CFR 1910.1200)
  • Dispose of waste acid in accordance with applicable federal, state, and local regulations
  • Consult your facility's Process Safety Management (PSM) program if applicable
