Abstract
Example methods, systems, and computer readable media are provided for monitoring operating processes. An example method includes monitoring an equipment parameter associated with an asset in an operating process unit and monitoring a process parameter associated with the asset. The example method includes determining an asset health corresponding to the asset. The asset health is determined based on a potential state of corrosion associated with the asset by comparing a corrosivity index to a corrosion threshold. The corrosivity index is a function of at least one of current values or changes in the monitored equipment parameter or the monitored process parameter over time.
Claims21
A method comprising:
- monitoring an equipment parameter associated with an asset in an operating process unit;
- monitoring a process parameter associated with the asset;
- and
- determining an asset health value corresponding to the asset, the asset health value being determined based on a potential state of corrosion associated with the asset by comparing a corrosivity index to a corrosion threshold, the corrosivity index being a function of at least one of current values or changes in the monitored equipment parameter or the monitored process parameter over time.
A system comprising:
- a monitoring application to monitor a equipment parameter and a process parameter associated with an asset in a process unit;
- and
- an asset health value calculator to determine an asset health corresponding to the asset, the asset health being determined based on thermal stress associated with the asset by comparing a thermal stress index to a thermal stress threshold, the thermal stress index being a function of changes of the monitored equipment parameter or the monitored process parameter over time.
A tangible computer readable storage medium comprising instructions that, when executed, cause a computing device to at least:
- monitor an equipment parameter associated with an asset in an operating process unit;
- monitor a process parameter associated with the asset;
- and
- determine an asset health corresponding to the asset, the asset health being determined based on a potential state of corrosion associated with the asset by comparing a corrosivity index to a corrosion threshold, the corrosivity index being a function of at least one of current values or changes in the monitored equipment parameter or the monitored process parameter over time.
