Ammonium Salt Corrosion Analysis and Risk-bask management of Hydro-processing Reactor Effluent System

Based on the Risk-based Inspection(RBI) research of hydro-processing reactor effluent system for many years, the ammoniasalt corrosion was analyzed. Suggestions of how to reduce and prevent the corrosion failure was provided, In reference to experiences abroad, the risk-based Risk-based Inspection (RBM) of the unit was strengthened.
