Effects of ammonia and hydrazine on desalter beds

When hydrazine is used in large quantities, excess hydrazine will consume the exchange capacity of the desalter resin and cause it to fail. The purpose of adding ammonia is to increase the ph value of feed water and reduce the corrosion of co2. In the process of desalination, regularly discharged part of the resin has failed and replenish an equal amount of the resin has been regenerated, was discharged from the failure of the resin in another special equipment for regeneration and cleaning, such a way of desalination treatment, known as the moving bed desalination treatment.
