Definitions

  • the present invention falls within the field of technologies applicable to the primary petroleum production and processing unit. More precisely, it falls within the field of mechanisms for recovering flare gas, which have been used in primary oil production and processing units.
  • the present invention in this sense, makes it possible to control flare gas recovery systems efficiently, continuously and automatically.
  • a flare is a structure that releases vapor or flame through its top portion. More precisely, the flare is a gas combustion structure, which performs controlled burning of waste and, in this way, is mainly found in refineries, chemical plants, petrochemical plants, natural gas processing plants, exploration platforms, among others.
  • the volume of all gas burned in the flare is computed and reported daily to the National Petroleum Agency (ANP), which assigns a maximum monthly burning limit for each unit in operation.
  • ANP National Petroleum Agency
  • the gas burned in the flare is a loss both commercially and for the environment, as, when it is no longer re-injected into the well or exported, it becomes a volume released into the atmosphere, aggravating the greenhouse effect (GHG). Furthermore, the volume of salable gas that is not flared for operational safety reasons is also subject to the payment of royalties and, if this volume exceeds the monthly flare limit agreed by the agency, it will be a production limiter.
  • the flare gas recovery systems present in some production units had an operational control method with the following configurations:
