Zinc Carbonate – For Oil & Gas

Zinc Carbonate

  • Zinc Carbonate (Transparent Zinc) is an excellent scavenger for hydrogen sulphide present in the oil wells.
  • Zinc Carbonate has the following benefits when used as a scavenger for hydrogen sulphide present in the oil wells:
  • Zinc carbonate reacts with hydrogen sulfide to form zinc sulfide or zinc bisulfide which is insoluble in water.

𝑍𝑛𝐶𝑂3 + 𝐻2𝑆 → 𝑍𝑛𝑆 ↓

  • Reaction rate of zinc carbonate is high because of its very small particle size and very high surface area.
  • More effective than zinc oxide and iron-based salts
  • Relatively economical
  • Can be used in both water based and oil-based fluids

Usage recommendation

  • Must be used in a fluid with pH higher than 9-10 (alkaline media) for effective removal of hydrogen sulfide
  • About 1 lb/bbl of zinc carbonate should be used for every 800 mg/litre of sulfides detected
  • (The above formula is only an indicative formula and the customer is requested to formulate their own individual formulation for their application depending on the hydrogen sulfide concentration.)

Storage And Handling Guidelines

  • Provided in 20 kg and 25 kg plastic/paper sacks
  • Store in dry conditions away from direct sunlight
