Crude Oil Changeover AI system


Crude oil changeover AI System

The crude oil changeover AI system is an AI application that learnt the correlation of operating parameters using plant operation data, dynamic simulators, and AI technology (deep reinforcement learning).
The crude oil changeover AI system provides optimal operating parameters in real time during the switching operation, and contributes the optimal operation in terms of energy saving, product loss minimization, reducing operation restriction, and early switching completion etc..

  • AI Prediction: AI prediction and visualization of important instruments and quality data of products.
  • Visualization of operating status: Visualization of tray load, heat exchanger dirtiness, etc.
  • Changeover evaluation: Technology transfer of advanced operation knowledge and skills to junior operators
  • Optimization of operating parameters: Increase of middle distillate amount (minimize Residual oil), shortening of crude oil changeover time, optimization of heat balance
Value Proposition
  • Operation optimization:
    • Application for the crude distillation unit that performs crude oil switching operation about 100 times / year (advanced control application is difficult and forced to manual operation)
    • Improving yield of products and energy loss by optimum operating parameters
  • Technology transfer:Supporting advanced operation knowledge and skills by Switching operation evaluation
