Reduction of Ammonical Nitrogen During Shock load in Crude Refining Industry

Abstract

The Project is based on Reduction of Ammonical Nitrogen from the waste water of Refinery. Where the Shock loads occurs
during the leakages, spillages, washing and cleaning of some vessels which leads to high oil content in waste water. During the
shock loads the Ammonical Nitrogen value exceeds the design capacity of treatment plant and formed Ammonical Nitrogen goes
to the ETP where it is needed to be removed so it becomes inefficient to remove it. Thus we have determined process for the
reduction of Ammonical Nitrogen value during the shock loads by studying and working on Breakpoint Chlorination Method.
After implementation of Breakpoint Chlorination method the desired results can be obtained which can help the industry to
maintain the discharge standards of the final effluent. In this method we even modified the method by varying the pH and
temperature for efficient removal. Further study can be done to reduce Ammonical Nitrogen in a more efficient manner by adding
different catalyst.
