Intrinsically safe fieldbus for hydrocarbon processing plants
The key issue is delivering enough power to a large number of field devices
Effective pH control through intelligent automation
This technology can improve reliability while reducing operating costs
Zero-lag exponential moving average for real-time control and noisy data processing
The filtering technology has no time delay
Model-free adaptive control technology enables ethylene quench water pH control
PetroChina has improved ethylene production efficiency and plant safety
Controlling hydrocracker reactor temperature
Avoid safety incidents and runaway reactions
Faster plant testing and modeling
Automated technology performs both open-loop and closed-loop testing simultaneously
Set vapor velocity setpoints profitably
Use Clifftent principles to account for operating limit tradeoffs and risk to substantially improve financial performance
Dynamic real-time optimization increases ethylene plant profits
This project resulted in a $12.5 million/yr profit increase and one-month payback
Fieldbus enables single-loop integrity with control-in-the-field
Benefits include device and process health monitoring that enable establishing asset management and predictive maintenance practices
Determining plant equipment performance during transient conditions
Steady-state performance algorithms can be modified to improve accuracy
