The initial treatment of zinc carbonate is usually 1.5 to 3 lb/bbl (3.75 to 8.0 kg/m3), depending on requirements. Subsequent field treatments should be based on approximately 1 lb/bbl (2.85 kg/m3) of zinc carbonate per 800 mg/L of sulfides detected.

One hundred kilograms (kg) of zinc carbonate reacts with approximately 25 kg of hydrogen sulfide. Use a Garrett Gas Train and proper Dräger tubes to measure the sulfide content. Zinccarbonate scavenger should be added through the hopper.

The product has a fine particle size and good dispersibility which minimizes reaction time. The use of excessively high pH (>11.5) should be avoided when using zinc carbonate scavenger in water-base fluids, as extreme viscosity increases are likely.
• Is not pH-dependent; it is effective at alkaline pH, such as 10 to 11, whereas iron materials are less so
• Helps remove the hazard of dangerous H2S gas escaping to the surface
• Lessens the possibility of hydrogen embrittlement occurring on downhole tubulars
• zinc carbonate can be used in oil- and synthetic-base fluids, but pilot testing is recommended

Usage: 

1.For industrial wastewater treatment and recycle. It has special efficacy for the Settlement of positive charge metal oxides.The usage amount is Just 1% of traditional flocculating agents and the efficiency is perfect. Such as steel mill,Metallurgical Plant and coal washery waste water. 
2.Settlement of river sediment / streamsediment
3.Retention and drainage aids, as well as dry strength agent in the Papermaking industry
