Application of Oil-based Cleaning and Deodorization Passivation Technology in Shutdown Process of a 10 Mt·a-1 Distillation Unit
Through the practical application of chemical cleaning and deodorization passivation technology in the shutdown process of 10 Mt·a-1 atmospheric and vacuum units,the possibility of using"oil-based chemical cleaning+hot water skimming+deodorization+passivation"technology in the shutdown process of large refining and chemical units to achieve safe,environmental protection and high-quality shutdown was demonstrated.At the same time,by comparing with traditional shutdown technology and combining with practical application experience,a detailed chemical cleaning plan for complex shutdown was proposed,being beneficial to the shutdown of large refining and chemical plants for reference.
