Definitions

  • This certificate of addition relates to improvements to the safety system which is the subject of the main patent, which is intended to eliminate any risk of liquids entrained at the torch nose or in the vent during flaring or dispersion of the gases associated with the production or processing of hydrocarbons on land and at sea.
  • this system involves, in the gas flow chain, between the source of entrainment of liquids and the nose of the torch or the vent, at least one capacity such as a torch base balloon, provided with an overflow column opening below a liquid level, for example the sea, at a determined distance from its tapping on said capacity.
  • at least one capacity such as a torch base balloon, provided with an overflow column opening below a liquid level, for example the sea, at a determined distance from its tapping on said capacity.
  • a first improvement according to the invention aims to avoid, in the event of a liquid spill in the overflow column, the retention and trapping of gas in the spilled liquid, or below it, which this would result in random operation of the entire security system previously described.
  • This improvement therefore consists in providing a circuit such as a strainer tube inside the overflow column or a duct outside of it, for raising the gases, allowing evacuation to the installations located upstream of the overflow, existing gases or liquids entrained in the overflow column.
  • the invention also relates to a second improvement making it possible to improve the operating safety of the overflow column, by detecting an abnormally high level of liquid in the above-mentioned overflow tube.
  • the tube overflow may lose its quality of safety by partial or total blockage thereof, or by a subsequent resizing of the installations placed upstream, leading to flow rates of liquid which may be discharged into the overflow column incompatible with the initial dimensioning thereof.
  • the second improvement of the security system therefore consists, according to the invention, in equipping the overflow column with one or more detection members making it possible to detect the presence of hydrocarbons at an abnormal level.
  • detection members may consist of high level detectors placed in the aerial part of the overflow column, or one or more pressure detectors, differential or not, placed more generally in the lower part of the overflow column. -full.
  • These detectors can also be designed so as to detect the presence of hydrocarbons, for example by optical effect, by capacitive effect, by magnetic effect, by electromagnetic effect or also by measurement of vibratory phenomena.
  • All these detectors can be placed either in the overflow column or outside and can be protected or not by an annexed tubing.
  • This verification may for example consist of an injection of water at a known rate in all or part of the entire security system, the injection being carried out at any point of the installation, but of to allow verification of the operation of all or part of the security system.
  • the subject of the invention is also a third improvement making it possible to increase the retention capacity of the spilled liquids and finally to improve the overall safety of the system, by multiplying the number of overflow columns, this, also for the purpose, not to create localized constraints that are too great, given the retention capacity sought.
  • overflow tubes For this purpose a multiplicity of overflow tubes can be used, these can be installed in favorable areas, all or part of the existing underlying structures can for example be used for their realization.
  • the commissioning of these overflow columns may if necessary be made when the installation is commissioned for the first time, or partially deferred dana. the time following the required change in the capacity of the installation.
  • Each of the overflow columns is equipped with the previous improvements if necessary.
  • the safety system to which the improvements according to the invention apply is intended to equip installations for the production of hydrocarbons on land and at sea.
  • These installations may include, as described in the main patent, a drive source for liquid hydrocarbons constituted by a separator receiving crude oil or gas through an inlet pipe.
  • This separator can be fitted, in a conventional manner, with a normal recovery circuit for oil or condensates and with a gas outlet connected to a gas flow chain up to the nose of the torch.
  • This gas flow chain comprises, between the separator and the nose of the torch, a torch base balloon (or equivalent) equipped, in a conventional manner with a drip recovery circuit which may include a pump.
  • These installations further comprise, according to the main patent, an overflow column coming to be stuck on the torch foot ball at a location corresponding to a predetermined maximum level and opening out below the sea level at a predetermined distance, below the stitching on said balloon.
  • FIGS. 1 and 2 of this certificate of addition.
  • d t entrainment of gases 2 and connected, in its upper part, to the torch barrel 3.
  • On this torch foot balloon 1 is also stuck an overflow column 4, at a location corresponding to a predetermined maximum level, and opening below sea level 5, 6.
  • this overflow column 4 includes, inside, a strainer tube 7 substantially coaxial and of smaller cross section than that of said column 4.
  • this screened tube 7 is placed at the lowest, in the vicinity of the lowest level 6 reached by the water inside the overflow column 4 in the event of operation of the system.
  • the point of tapping 10 of the strainer tube will be located at a point in the circuit for venting the gases, such that the separation of the liquids, possibly entrained by the rising gases, can be carried out before venting the gases.
  • the horizontal or subhorizontal part 12 of the overflow column 4 may, preferably, but not necessarily, open tangentially into the vertical or subvertical part of the overflow column 4, in order to minimize trapping or the entrainment of gas in said column 4.
  • the inner surface of the upper end of the vertical part of the overflow column 4 may, preferably but not necessarily, be equipped with devices, by example of the guide fins or helical ramps generating a helical movement of descending liquids in the overflow column 4, this in order to promote the flow of the descending liquids and to create a central chimney for the evacuation of the trapped gases below liquids or entrained by them.
  • the winding direction, of the guide ramps for example, will depend on the terrestrial hemisphere on which it is located, (to take account of the forces of Coriolis).
  • FIG. 2 relates to a second embodiment of a circuit allowing the evacuation of the gases inside the overflow column 4.
  • This circuit which makes it possible to obtain effects similar to those obtained using the Strainer tube previously described, differs from it, however, by the fact that it involves for the evacuation of the gases trapped in the overflow column 4, an evacuation tube 13 placed outside.
  • This discharge tube 13 (vertical) which is placed substantially parallel to the overflow column 4 communicates with the latter by a series of possibly horizontal tubes 14 allowing the evacuation of the trapped gases at different levels.
  • this discharge tube 13 is connected to the torch base balloon 1 at a point 16 located above the nozzle 17 of the overflow column 4 on said balloon 1, it being understood that this connection could also be carried out on the torch barrel 3 in the case where it plays the role of the torch base balloon.
