Ammonium bi sulphite Nickel catalysed is widely used in oil field as oxygen
scavenger and/or corrosion inhibitor. Its function is to remove oxygen from the
water. Generally for 1 ppm of dissolved oxygen in water with retention of 5 mints the
ABS used will be 9.5ppm Max. As it is Nickel catalysed the consumption or the
reaction time may reduce depending on application. Other than this there are several
more application like in Photography industry, Agro industry, and Pharmaceutical
industry and as a specialty chemicals
