Zinc Oxide sulphide scavenger contains a high quality ZnO, very fine particle size causes high surface area (BET)
for fast, efficient sulphide scavenging. It reacts with sulphides to form Zinc Sulphide as precipitate.
Zinc oxide scavenger is effective at the pH level found in drilling fluids. It is recommended that a pH above 11 be maintained whenever H2S is expected. This high alkalinity converts the dangerous H2S gas to less toxic bisulfides and sulphides ions and safe to use . ZnO can be used in oil-and synthetic – base fluids after approving small trials Active Zn content is >90% as compared to ZnCO3./ZnSO4. Remove hazard H2S gas escaping at the surface. Reduce the possibility of Hydrogen embrittlement occurring on downhole tubular.
