Abstract
The current disclosure relates to steam generation and supply apparati and associated control systems. Particularly, the current disclosure relates to such steam generation supply apparati and associated control systems that are used for enhanced oil recovery. Certain embodiments are provided including methods and associated control systems related to the startup as well as main steam pressure header control or maintenance of a desired steam quality for such steam generation systems during normal operation.
Claims17
A method of predicting or attaining a desired steam quality of at least one of water and steam supplied by an apparatus capable of producing at least one of water and steam of varying quality, the apparatus comprising a feedwater supply system, a steam generation system and a delivery system, the method comprising:
- determining a feedwater enthalpy and a feedwater flow rate;
- setting the desired steam quality of at least one of water and steam;
- and
- estimating an enthalpy of the desired steam quality of at least one of water and steam.
