1. A flash tank comprising: a shell including an inner volume; anda first port in fluid communication with said inner volume and positioned relative to a surface of said inner volume such that fluid flows between said first port and said inner volume in a direction that is substantially tangent to said surface. 2. The flash tank of claim 1, wherein said first port is formed through a middle portion of said shell. 3. The flash tank of claim 1, wherein said first port is spaced apart from a bottom portion of said shell by a distance between approximately one-third and one-half of a total height of said shell. 4. The flash tank of claim 1, wherein said first port includes a first portion and a second portion cooperating to define a substantially L-shape. 5. The flash tank of claim 4, wherein said first portion includes an expansion volume to slow down a velocity of fluid entering said shell. 6. The flash tank of claim 1, further comprising internal baffles disposed within said shell. 7. The flash tank of claim 6, wherein said internal baffles are formed substantially perpendicular to a longitudinally extending surface of said shell. 8. The flash tank of claim 6, wherein said internal baffles are formed at an angle relative to a longitudinally extending surface of said shell. 9. The flash tank of claim 6, wherein said internal baffles include at least one through hole. 10. The flash tank of claim 6, wherein said internal baffles are positioned relative to said first port to receive fluid directly from said first port. 11. The flash tank of claim 1, further comprising a second port disposed proximate to a bottom portion of said shell, said second port being in fluid communication with said inner volume. 12. The flash tank of claim 1, further comprising a disk disposed within said shell to separate a liquid portion of said shell from a vapor portion of said shell. 13. The flash tank of claim 12, wherein said disk is a top surface of an internal shell disposed within said shell. 14. The flash tank of claim 12, wherein said disk is spaced apart from a bottom portion of said shell by a distance approximately equal to two thirds of a total height of said shell. 15. The flash tank of claim 12, wherein said disk includes at least one aperture to allow fluid communication between said liquid portion and said vapor portion. 16. The flash tank of claim 12, wherein said disk includes a tube extending from a top surface thereof and into said vapor potion. 17. The flash tank of claim 12, further comprising a recirculation tube formed through a middle portion of said shell to receive liquid from said liquid portion when said liquid portion exceeds a predetermined level within said shell. 18. The flash tank of claim 17, wherein said recirculation tube is fluidly coupled to a second port in fluid communication with said inner volume. 19. The flash tank of claim 1, further comprising a recirculation tube formed through a middle portion of said shell to remove liquid from said shell when said liquid reaches a predetermined level within said shell. 20. The flash tank of claim 19, wherein said recirculation tube is fluidly coupled to a second port in fluid communication with said inner volume. 21. The flash tank of claim 1, further comprising a sight glass disposed in said shell for viewing a fluid level within said shell. 22. The flash tank of claim 1, further comprising a liquid level sensor in communication with said inner volume and determining a fluid level within said shell. 23. The flash tank of claim 1, wherein said shell includes a height-to-diameter aspect ratio between approximately four and six. 24. A flash tank comprising: a shell including an inner volume and having a height-to-diameter aspect ratio between approximately four and six;a first port in fluid communication with said inner volume and operable as an inlet in a first mode and as an outlet in a second mode; anda second port in fluid communication with said inner volume and operable as an outlet in said first mode and as an inlet in said second mode;wherein said first port is formed tangentially to an inner surface of said shell. 25. The flash tank of claim 24, wherein said first port is formed through a middle portion of said inner volume disposed between top and bottom portions of said inner volume. 26. The flash tank of claim 25, wherein said first port is spaced apart from said bottom portion by a distance approximately equal to one third or no more than half of a total height of said shell. 27. The flash tank of claim 24, wherein said first port includes a first portion formed perpendicular to said shell and a second portion formed substantially parallel to said shell such that said first portion and said second portion cooperate to define a substantially L-shape. 28. The flash tank of claim 27, wherein said first portion includes an expansion volume to slow down a velocity of fluid entering said shell. 29. The flash tank of claim 24, further comprising internal baffles disposed within said shell. 30. The flash tank of claim 29, wherein said internal baffles are formed substantially perpendicular to a middle portion of said inner volume, said middle portion disposed between top and bottom portions of said inner volume. 31. The flash tank of claim 29, wherein said internal baffles are formed at an angle relative to a middle portion of said inner volume, said middle portion disposed between top and bottom portions of said inner volume. 32. The flash tank of claim 29, wherein said internal baffles include at least one through hole. 33. The flash tank of claim 29, wherein said internal baffles are positioned relative to said first port to receive fluid directly from said first port. 34. The flash tank of claim 24, wherein said second port is disposed proximate to a bottom portion of said shell. 35. The flash tank of claim 24, further comprising a disk disposed within said shell to separate a liquid portion of said shell from a vapor portion of said shell. 36. The flash tank of claim 35, wherein said disk is a top surface of an internal shell disposed within said shell. 37. The flash tank of claim 35, wherein said disk is spaced apart from a bottom portion of said inner volume by a distance approximately equal to two-thirds of a total height of said shell. 38. The flash tank of claim 35, wherein said disk includes at least one aperture to allow fluid communication between said liquid portion and said vapor portion. 39. The flash tank of claim 35, wherein said disk includes a tube extending from a top surface thereof and into said vapor potion. 40. The flash tank of claim 35, further comprising a recirculation tube formed through a middle portion of said inner volume to receive liquid from said liquid portion when said liquid portion exceeds a predetermined level within said shell. 41. The flash tank of claim 40, wherein said recirculation tube is fluidly coupled to said second port. 42. The flash tank of claim 24, further comprising a recirculation tube formed through a middle portion of said inner volume to remove liquid from said shell when said liquid reaches a predetermined level within said shell. 43.
