Product Overview & Chemical Characteristics
Ammonium Bisulphite Nickel is a premier catalyzed oxygen scavenger solution incorporating homogeneous nickel catalyst complexes (Ni2+ ions).
Standard bisulphite reactions slow down considerably in cold waters (such as North Sea or deep subsea injection). The introduction of trace, tightly controlled nickel catalyst lowers activation energy, speeding up oxygen elimination by up to 10x even in low-temperature waters.
Key Advantages:
• Rapid oxygen scavenging at cold seawater temperatures (4°C to 15°C)
• Reduces necessary contact vessel retention time
• Proven track record in offshore oil platform seawater injection
