Process Control
Foundation fieldbus – open, integrated fieldbus architecture
Here’s how the technology helps support plant optimization
Consider process control a specialty within chemical engineering – Part 1
Incorporating more process reactions in the unit's P&I, engineers will be able to design better control systems
Setpoint tuning method gives excellent response to load changes
The technique has been thoroughly tested with simulations and actual control loops
Rationalizing PID tuning with a model-based approach
The method provides flexibility in using any PID algorithm, process transfer function and test pattern
Consider a neuro-fuzzy system to model a delayed coking process
Soft-sensing techniques can be used to achieve realistic control models
HPInternet: Why do gasoline prices go up and down?
We in the industry know why gasoline prices fluctuate. It's because of the price of crude oil or demand for product or government adding more environmental costs or high taxes or refine..
Plant information (OPC data management)
Application. Matrikon's OPC Data Manager (ODM) is a software application that transfers data from one OPC server to another. Use ODM when you need to share data between two or more cont..

Careful planning reduced costs and avoided having to shut down the plants
HPInternet: Coordinating Research Council
If you are in the downstream industry where the fuel meets the automobile, you have probably heard about the Coordinating Research Council (CRC). CRC is a nonprofit organization that direct..
HP Control: Consider MRA
About five years ago, Invensys introduced what we considered to be an innovative online process analyzer based on nuclear magnetic resonance technology (see "HP Innovations," March 1998) which it call..
