Abstract
The current disclosure relates to a method of steam generation. Particularly, the current disclosure relates to 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
A method of running an apparatus capable of producing at least one of water and steam at a desired injection pressure to a desired destination, the apparatus including a feedwater supply system that includes a first feedwater pump recirculation control loop that controls a feedwater flow rate based on a measured flow rate, a steam generation system and a delivery system that includes a main steam header pipe that runs from the steam generation system to a destination and a second control loop that controls the feedwater flow rate based on an injection pressure, the method comprising the following steps:
- determining whether the injection pressure is within acceptable parameters;
- and adjusting the feedwater flow rate if the injection pressure is not within acceptable parameters.
