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.
Claims15
An apparatus for supplying at least one of water and steam to a desired destination at a desired injection pressure comprising:
- a feedwater system that includes a feedwater pump and a first feedwater recirculation control loop that varies the feedwater flow rate based on the flow rate;
- a steam generation system;
- a delivery system that includes a main steam header pipe that runs from the steam generation system to the desired destination and a second control loop for controlling the feedwater flow rate based on the injection pressure of at least one of water and steam;
- a plurality of instruments and devices that are in operative association with the feedwater system or delivery system configured for sensing physical parameters of water or steam and for controlling the feedwater flow rate and the injection pressure of the steam or water;
- and
- a control system having an input device, output device and memory, said control system being in operative association or communication with said instruments and devices.
