Flare Stack

Abstract

In one aspect there is provided a gas flare comprising a hollow cylindrical member having a bottom end, a top end, a discharge end at said top end, and defining an interior volume having a mixing region. The gas flare further comprises a gas inlet to receive waste fluids, an air inlet to receive and direct air into the interior volume, and an internal riser having an outlet. The mixing region is located above the air inlet and below the discharge end. The internal riser fluidly and sealably connects to the gas inlet and directs all waste fluids from the gas inlet, out through the outlet, into the mixing region.

1 . A gas flare comprising:
 a hollow cylindrical member having a bottom end, a top end, a discharge end at said top end, and defining an interior volume having a mixing region;   a gas inlet to receive waste fluids;   an air inlet to receive and direct air into the interior volume; and   an internal riser having an outlet;   wherein said mixing region is above the air inlet and below the discharge end;   wherein the internal riser fluidly and sealably connects to the gas inlet and directs all waste fluids from the gas inlet, out through the outlet, into the mixing region.   
     
     
         2 . The gas flare of  claim 1  wherein the hollow cylindrical member further comprises:
 a flare section; and 
 a stack section. 
 
     
     
         3 . The gas flare of  claim 2  wherein the flare section is mountable on top of the stack section by means of a connection. 
     
     
         4 . The gas flare of  claim 3  wherein the connection is a hinged connection. 
     
     
         5 . The gas flare of  claim 3  wherein the connection is a flanged connection. 
     
     
         6 . The gas flare of  claim 1  wherein the internal riser is mounted substantially centrally and coaxially within the interior volume, thereby defining an annulus within said interior volume. 
     
     
         7 . The gas flare of  claim 6  wherein the air inlet directs air into the annulus. 
     
     
         8 . The gas flare of  claim 7  further comprising an air inlet valve to control the amount of air entering in the annulus via the air inlet. 
     
     
         9 . The gas flare of  claim 3  wherein the internal riser extends up along the interior volume so as to position the riser's outlet just below the connection. 
     
     
         10 . The gas flare of  claim 9  wherein the mixing region extends the outlet to the discharge end. 
     
     
         11 . The gas flare of  claim 1  further comprising a drain positioned substantially at the bottom end. 
     
     
         12 . The gas flare of  claim 11  further comprising a drain valve to open or close said drain. 
     
     
         13 . The gas flare of  claim 12  wherein the drain is located below the air inlet, thereby defining a sump region. 
     
     
         14 . A gas flare comprising:
 a hollow cylindrical member having an inlet end, a discharge end, and defining an interior volume having a mixing region;   a gas inlet to receive waste fluids;   an air inlet to receive and direct air into the interior volume; and   an tubular member having an outlet;   wherein said mixing region is above the air inlet and below the discharge end;   wherein the tubular member fluidly and sealably connects to the gas inlet and directs all waste fluids from the gas inlet, out through the outlet, into the mixing region.   
     
     
         15 . The gas flare of  claim 14  wherein the tubular member is mounted substantially centrally and coaxially within the interior volume, thereby defining an annulus within said interior volume. 
     
     
         16 . The gas flare of  claim 15  wherein the air inlet directs air into the annulus. 
     
     
         17 . The gas flare of  claim 16  further comprising an air inlet valve to control the amount of air entering in the annulus via the air inlet.
