Definitions

  • Hydrocarbons are widely used as a primary source of energy, and have a significant impact on the world economy. Consequently, the discovery and efficient production of hydrocarbon resources is increasingly important. As relatively accessible hydrocarbon deposits are depleted, hydrocarbon prospecting and production has expanded to new regions that may be more difficult to reach and/or may pose new technological challenges.
  • a borehole is drilled into the earth, whether on land or below the sea, to reach a reservoir containing hydrocarbons.
  • Such hydrocarbons are typically in the form of oil, gas, or mixtures thereof which may then be brought to the surface through the borehole.
  • Well testing is often performed to help evaluate the possible production value of a reservoir.
  • a test well is drilled to produce a test flow of fluid from the reservoir.
  • key parameters such as fluid pressure and fluid flow rate are monitored over a time period.
  • the response of those parameters may be determined during various types of well tests, such as pressure drawdown, interference, reservoir limit tests, and other tests generally known by those skilled in the art.
  • the data collected during well testing may be used to assess the economic viability of the reservoir.
  • the costs associated with performing the testing operations are significant, however, and may exceed the cost of drilling the test well. Accordingly, testing operations should be performed as efficiently and economically as possible.
  • a Coanda surface is merely a curved surface designed for the adherence of a fluid. Fluid streams injected on or adjacent to a Coanda surface tend to adhere to and follow the path of the surface. The negative pressure pulls the fluid against the surface. The fluid stream is spread into a relatively thin film or sheet, which allows proximate fluids to be mixed in with the fluid stream in a very efficient manner. The additional surface area imparted to the gas significantly enhances mixing.
  • Coanda flares provide relatively clean combustion by premixing the waste gas with ambient air prior to combustion. Coanda flares also offer generally good, stable flame combustion at high inlet pressures of the combustible gas.
  • flow velocity perturbations in Shockwaves generated in the general vicinity of the gas exit slot of a Coanda flare may atomize liquid droplets entrained in the gas flow, thereby generated a fine mist that facilitates combustion and reduces the risk of fall out even where there is significant liquid carryover in the flare line.
  • Coanda-type flare systems offer stable and clean combustion of multiphase hydrocarbon effluents, and may be operated in an efficient and environmentally friendly manner.
  • well test separators may be used to separate the well effluent into its individual phases, such as oil, water, and gas. This approach requires additional separating equipment and increases the footprint needed for the well test system, which may be a significant concern in certain applications, such as on offshore platforms.
  • Coanda-shaped burners may generate a supersonic jet of fluid that creates Shockwaves close to a surface of the burner.
  • Prandl-GIauert condensation clouds may develop behind an air vehicle traveling at near-sonic velocities through a high-humidity atmosphere. Shockwaves generated near the vehicle may create a local zone of high pressure that precedes the shockwave and a local zone of low pressure that follows the shockwave. Before ambient air can fill the low pressure zone, the temperature of the gas present in the low pressure zone will decrease sharply to a very low temperature (down to 150K).
  • the condensed water droplets When the temperature drop trailing the shockwave is severe, the condensed water droplets may be converted into ice and stick to the tulip-shaped body. This effect may be applied to Coanda flare systems, where a significant pressure drop at the exit of a nozzle may freeze the liquid component of the waste flow, thereby halting or decreasing the efficiency of the waste gas combustion.
  • a flare for combusting waste effluent from a reservoir.
  • the waste effluent flare may include a supply pipe configured to fluidly communicate with the reservoir so that a flow of waste effluent travels through the supply pipe, and may include a supply pipe inner surface and a supply pipe discharge end.
  • the flare may further include a flare body extending along a flare body axis.
  • the flare body may have a stem disposed within the supply pipe and extending substantially coaxially along the flare body axis, and a stem outer surface spaced from the supply pipe inner surface to define an annular gap therebetween.
  • the flare body may also include a head having a streamlined shaped exterior surface.
  • a transition section of the head may be coupled to the stem and include an annular bulge extending circumferentially around and projecting outwardly from an exterior surface of the transition section.
  • the bulge may be substantially axially aligned with the annular gap.
  • the flare body head may include an initial portion substantially axially aligned with the gap and extending at a deflection angle relative to the flare body axis, wherein the deflection angle is approximately 40 to 70 degrees.
  • an atomization tube may be coupled to the flare body stem and have an inlet end fluidly communicating with the supply pipe and an outlet end disposed in a body chamber defined by the flare body, wherein the outlet end defines a discharge orifice.
  • FIG. 1 is a side elevation view, in partial cross-section, of a first embodiment of a waste effluent flare constructed according to the present disclosure.
  • FIG. 2 is a side elevation view, in partial cross-section, of a second embodiment of a waste effluent flare constructed according to the present disclosure
  • FIG. 3 is a side elevation view, in partial cross-section, of a third embodiment of a waste effluent flare constructed according to the present disclosure
  • FIG. 4 is a side elevation view, in cross-section, of a Coanda-shaped gas flare constructed according to the prior art.
  • Coanda and Coanda-shaped are generally understood by those of skill in the art to define a flare body geometry that facilitates a jet of fluid that closely adheres to the flare body surface.
  • the Coanda surface may alternatively be referred to as having a tulip shape, because the smooth, concentric geometry emulates the shape of that flower. Regardless, this type of phenomenon, like in the presently disclosed embodiments, may be present or can be achieved without having the typical Coanda or tulip shape.
  • the waste effluent flare is used to burn, or combust, waste effluent from a supply flowline.
  • the generic term used to describe such waste effluent is often roughly termed a gas flow to be combusted.
  • the gas flow is often a multiphase flow, in which a fraction of liquid remains in the gas flow to be combusted.
  • a Coanda-type flare is often useful to combust the liquid fraction, since the gas flow ejected from the Coanda flare reaches supersonic speeds.
  • the flow velocity perturbations in Shockwaves created by these speeds disperse the liquid fraction in the gas flow into a fine mist that is more easily combusted by the burner flame.
  • the waste effluent (which may be a single-phase or dual-phase fluid) flows closely to the surface of the flare and may entrain primary air.
  • FIG. 4 provides a vertical cross-section of a prior art arrangement for a Coanda style flare 400. More specifically, the fiare 400 includes a tulip-shaped body 402 coupled to a base member 404 disposed within a supply pipeline 406. A slot 408 is provided between the supply pipeline 406 and the body 402 through which waste effluent may flow.
  • the tulip shape of the body 402 produces the Coanda effect, during which the waste effluent flow accelerates around the body 402 to create an area of low pressure. The low pressure area directs the waste effluent flow along the surface of the body 402 and also draws ambient air into the effluent flow.
  • the ambient air may mix with the waste effluent, produces a mixture that is more suitable for combustion by a burner flame provided at a distal end of the body 402.
  • the reduced cross-sectional area of the slot 408 may accelerate the waste effluent to sonic speeds.
  • Subsequent expansion of the waste effluent around the body 402 may generate supersonic flow velocities, which may produce Shockwave velocity perturbations that atomize liquid droplets entrained in the waste effluent flow.
  • the pre-mixing may produce a fuel-oxygen ratio that makes the flame more stable and clean.
  • an initial or upstream portion of the body 402 located near the base member 404 extends substantially normal to an axis 410 of the flare 400. This not only creates an abrupt change in effluent flow direction, but also causes solids entrained in the effluent flow to be projected substantially radially outwardly from the axis 410, thereby posing a risk to nearby personnel and equipment. Additionally, it will be appreciated that the body 402 has a smooth transition from the upstream portion of the body to the downstream portion of the body. Finally, the only means to control turndown ratio of the prior art flare 400 would be to adjust the area of the slot 408, and therefore the flare 400 has a limited turndown ratio.
  • FIG. 1 illustrates an embodiment of a waste effluent flare 100 for combusting waste effluent from a reservoir that is constructed according to the present disclosure.
  • the waste effluent flare 100 may include a supply pipe 102 configured to fluidly communicate with the reservoir so that a flow of waste effluent travels through the supply pipe 102.
  • the supply pipe 102 may include a supply pipe inner surface 104 and a supply pipe discharge end 106.
  • the supply pipe discharge end 106 may be generally open to permit waste effluent to flow outwardly in a generally axial direction.
  • the waste effluent flare 100 may also include a flare body 120 extending along a flare body axis 122.
  • the flare body 120 may include a stem 124 disposed within the supply pipe 102 and extending substantially coaxially along the flare body axis 122.
  • the stem 124 may have a stem outer surface 126 spaced from the supply pipe inner surface 104 to define an annular gap 128 therebetween through which waste effluent may flow.
  • the flare body 120 may also include a head 130 having an exterior surface 132 which promotes a waste effluent flow that closely follows the exterior surface 132.
  • the head 130 includes a transition section 134 coupled to the stem 124, a middle section 136 flaring outwardly from the transition section 134, and a distal section 138 defining a head discharge end 140.
  • the exterior surface 132 generally has axial symmetry with a variable curvature along the flare body axis 122. In the middle and distal sections 136, 138, the exterior surface 132 is substantially smooth with gradual changes in diameter to promote an effluent flow pattern 135 that closely follows the shape of the exterior surface 132.
  • the flow pattern 135 generates high velocity flows with resulting low pressures which draw ambient air 137 into the effluent, thereby mixing air with the effluent flow.
  • the transition section 134 may include an annular bulge 142 for dispersing liquid phase effluent into the effluent flow pattern 135.
  • the bulge 142 extends circumferential ly around and projects outwardly from an exterior surface 144 of the transition section 134.
  • the bulge 142 may be axially aligned with the annular gap 128 as shown in FIG. 1.
  • the bulge 142 may be formed by a ramp surface 146 and a relief surface 148.
  • the ramp surface may be positioned proximally to and extend outwardly from the stem 124, and the relief surface 148 may be positioned distally from the stem 124 and extend inwardly from the ramp surface 146.
  • the bulge 142 defines a sharp edge 149 which serves to disperse a liquid film traveling along the exterior surface of the flare body 120 into the gas flow pattern 135.
  • the liquid is typically dispersed as a fine mist, and therefore is more susceptible to clean and complete combustion.
  • the flare body 120 may be configured to more reliably generate the flow pattern 135 with the streamlined shape and to reduce the incidence of solids projecting radially outwardly from the flare body 120. More specifically, the initial portion of the flare body 120 that extends outwardly from the stem 124 may be oriented at a relatively small deflection angle "a" relative to the flare body axis 122. In the embodiment of FIG. 1, for example, the ramp surface 146 of the bulge 142 may form the initial portion of the flare body head 130 that diverts outwardly from the stem to receive and redirect the waste effluent exiting the supply pipe 102.
  • the ramp surface 146 may have a frustoconical shape that is oriented at a deflection angle a relative to the flare body axis.
  • the deflection angle a may be approximately 40 to 70 degrees. In other embodiments, the deflection angle a may be approximately 50-60 degrees. In still further embodiments, the deflection angle a may be approximately 55 degrees. In each of these embodiments, the deflection angle a is substantially less than that of the prior art embodiments, which are near 90 degrees. This reduced deflection angle a better promotes a streamlined flow pattern 135, and directs any solids entrained in the effluent flow substantially axially instead of radially. More specifically, solid particles may traverse the streamlined flow pattern 135 and be directed toward the flame zone provided distally of the flare body 120.
  • the waste effluent flare 100 may also be configured to alleviate rapid cooling associated with the low pressure area of effluent flow.
  • the bulge 142 may produce a high velocity waste flow immediately downstream of the bulge 142.
  • the increased velocity flow also creates an area of low pressure and a resulting drop in temperature that tends to freeze liquid fluid immediately downstream of the bulge 142.
  • the flare body 120 may include a body interior surface 150 defining a body chamber 152.
  • the transition section 134 of the flare body 120 may include a plurality of apertures 154, wherein each aperture 154 extends from the body interior surface 150 to an exterior surface 132 of the flare body 120.
  • the apertures 154 form two concentric bands 156, 158 extending circumferentially around the flare body 120, however the apertures 154 may be provided in other patterns and more bands. Each aperture may have a diameter of approximately 2 to 5 millimeters.
  • the apertures 154 direct warmer air from the body chamber 152 toward the area of low pressure immediately downstream of the bulge 142, thereby to prevent surface icing.
  • the size and number of apertures 154 may be selected such that they permit a sufficient amount of warm air flow to the exterior surface 132 while preventing a reverse flow of fluid into the body chamber 152.
  • the waste effluent flare 100 may include additional features for breaking up and/or atomizing liquids entrained in the waste effluent.
  • a plurality of supply pipe projections 190 may be formed at the supply pipe discharge end 106.
  • a plurality of head projections 192 may extend from the head discharge end 140.
  • the supply pipe projections 190 and head projections 192 may be formed as series of tabs that are shaped, such as triangular, to form discrete, spaced points.
  • the tabs may have a height (measured substantially parallel to the flare body axis 122) of approximately 1.5 to 6.0 millimeters. These points may help disperse liquid content of the waste effluent for improved mixing and subsequent combustion.
  • the supply pipe projections 190 may help disperse liquid that may travel along the supply pipe inner surface 104 into droplets or discrete streams that may more easily mix with the downstream effluent gas flow around the head 130.
  • the head projections 192 disperse liquid traveling along the exterior surface 132 for mixing with effluent gas and ambient air downstream of the head 130.
  • the head projections 192 also increase the turbulence of the gas flow to improve mixing and reduce noise.
  • the exterior surface 132 of the flare body head 130 may also be configured to promote dispersion of liquid entrained in the waste effluent. As shown in FIG. 1 , the exterior surface 132 downstream of the transition section 134 is substantially smooth with gradual changes in diameter. A groove 194 may be formed in the exterior surface 132 that forms a recessed surface 196. The groove 194 may be located such that it coincides with the maximum diameter of the head exterior surface 132. The groove 194 breaks up the flow of liquid along the exterior surface 132 of the flare body head 130 into droplets and/or smaller liquid jets, which are more easily mixed with effluent gas and combusted downstream of the flare body 120.
  • waste effluent flows through the supply pipe 102 and is discharged through the annular gap 128 toward the flare body head 130.
  • the gap 128 directs the waste effluent toward the bulge 142 which may define a reduced deflection angle a.
  • the gas portion of the waste effluent may be traveling at sonic speeds, which disperses any liquid portion of the waste effluent into a fine mist.
