There are two types of FCC AI Optimizers: FCC Convertor-status Prediction AI System and FCC Afterburn Prediction AI System, and either one or both systems can be introduced depending on your needs.

FCC Convertor-status Prediction AI System

These are the following operational challenges associated with complex reactions in the FCC Unit:

• Currently, it takes several weeks to grasp the catalyst properties including activity, and it is not possible to grasp them in real-time.
• In addition, the method for setting optimal operating conditions according to the crude oil type has not been established.

In response to these issues, Chiyoda's FCC reaction optimization AI learns the past operating conditions and presents the reaction conditions and optimal operating parameters of the FCC Unit in a timely manner.
We are also developing AI for optimizing the Cat/Oil ratio and Oil/Steam ratio, optimizing the FCC Unit operation according to crude oil type, and improving product yield.
In the future, we aim to further optimize operations by linking with RTO/APC (operation optimization/advanced control).

Benefits of Introduction

• Real-time presentation of reaction activity
• Reduces the amplitude of reaction activity
• Reduces the chance of a decrease in reaction activity
• Accurate operation at the reaction activity according to the production plan

FCC Afterburn Prediction AI System

The FCC regenerator has the following issues, especially when the operating load is high.

• There is a risk of damage to the cyclone, downstream piping, and other equipment due to poor combustion and afterburn.
• Therefore, the operating load cannot be increased to the required level.
• Since there are many factors that cause afterburn, it is difficult to take effective measures against afterburn.

To address these issues, Chiyoda's FCC Afterburn Prediction AI System predicts the following by learning from operation data and provides operation support.

• Predicts the occurrence of afterburn in advance
• Real-time mapping of changes in the severity of afterburn
• Simultaneously display the causes of afterburn

In the future, we aim to further optimize operations by linking with RTO/APC (operation optimization/advanced control).

Benefits of Introduction

• By predicting the occurrence of afterburn in advance, it is possible to avoid afterburn.
• Visualization of the degree of severity of afterburn makes it possible to understand the direction of the severity transition.
• Real-time visualization of the causes of afterburn provides hints for avoiding afterburn.
