Abstract
Systems and methods include a computer-implemented method for providing a predictive pressure protection system. Flare sources, performance limits, and relationships between control valves and relief valves are established. A flare simulator is generated using piping isometric drawings. An emergency event is monitored, and information for the emergency event is filtered based on a control valve limit breach. Event start and finish time periods are divided into cases representing smaller time frames. Source max loads are determined for each case, and each case is run through the flare simulator. Flare/relief valve performance indicators are determined based on the source max loads after running each case.
Claims20
A computer-implemented method for monitoring petroleum facilities, the method comprising:
- establishing flare sources, performance limits, and relationships between control valves and relief valves of the flare sources;
- generating a flare simulator of the flare sources using piping isometric drawings, wherein the flare simulator comprises a hydraulic model that uses a network model comprising the control valves, the relief valves, and piping extracted from the piping isometric drawings;
- monitoring an emergency event and filtering information for the emergency event based on a control valve limit breach;
- dividing start and finish time periods of the emergency event into a plurality of cases representing smaller time frames within the emergency event, wherein each of the plurality of cases represents a sub-part of the emergency event;
- determining source max loads for each case in the plurality of cases, and running each case through the flare simulator;
- and
- determining, based on the source max loads and the running of each case through the flare simulator, performance indicators of the relief valves and of a flare during the emergency event.
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations for monitoring petroleum facilities, the operations comprising:
- establishing flare sources, performance limits, and relationships between control valves and relief valves of the flare sources;
- generating a flare simulator of the flare sources using piping isometric drawings, wherein the flare simulator comprises a hydraulic model that uses a network model comprising the control valves, the relief valves, and piping extracted from the piping isometric drawings;
- monitoring an emergency event and filtering information for the emergency event based on a control valve limit breach;
- dividing start and finish time periods of the emergency event into a plurality of cases representing smaller time frames within the emergency event, wherein each of the plurality of cases represents a sub-part of the emergency event;
- determining source max loads for each case in the plurality of cases, and running each case through the flare simulator;
- and
- determining, based on the source max loads and the running of each case through the flare simulator, performance indicators of the relief valves and of a flare during the emergency event.
A computer-implemented system, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations for monitoring petroleum facilities, the operations comprising:
- establishing flare sources, performance limits, and relationships between control valves and relief valves of the flare sources;
- generating a flare simulator of the flare sources using piping isometric drawings, wherein the flare simulator comprises a hydraulic model that uses a network model comprising the control valves, the relief valves, and piping extracted from the piping isometric drawings;
- monitoring an emergency event and filtering information for the emergency event based on a control valve limit breach;
- dividing start and finish time periods of the emergency event into a plurality of cases representing smaller time frames within the emergency event, wherein each of the plurality of cases represents a sub-part of the emergency event;
- determining source max loads for each case in the plurality of cases, and running each case through the flare simulator;
- and
- determining, based on the source max loads and the running of each case through the flare simulator, performance indicators of the relief valves and of a flare during the emergency event.
