AI Technical Summary
Existing technologies make it difficult to achieve zero emissions from flare systems on offshore platforms, especially to extinguish the flare under normal production conditions and reduce flare gas emissions to improve project economics.
Design a flare system including a flare branch manifold, a flare main manifold, a flare distribution tank, a flare gas recovery system, a safety pressure regulating system, a flare ignition system, and a flare arm. The system uses a pressure transmitter to detect the gas flow pressure and triggers the switching of shut-off valves and quick-opening valves to achieve gas phase gas recovery under normal operating conditions or diversion combustion under emergency conditions. Combined with an automatic ignition device, the system ensures that the flare is extinguished.
This technology enables the liquid and gas phases of flare gas to be transported to downstream process systems for treatment under normal operating conditions, and diverted for combustion in emergency situations, achieving zero flare emissions and improving the economy and safety of offshore platforms.
