Abstract:
1. A fluid evaporation system comprising: An elongated housing having a floor and a roof that each extend between a first end and an opposing second end and opposing sidewalls that extend between the floor and the roof along the length of the floor and the roof, the housing bounding a fluid reservoir formed at or adjacent to the floor in which a fluid is disposed, the fluid comprising wastewater from an oil or gas well, the housing also bounding an air flow path that is disposed between the fluid reservoir and the roof and that communicates with the fluid reservoir; an inlet opening formed at the first end of the housing and communicating with the air flow path; an outlet opening formed on the roof at the second end of the housing and communicating with the air flow path; an elongated, tubular stack upwardly standing from the second end of the roof and communicating with the open environment outside of the housing, the tubular stack also communicating with the outlet opening so that the air passing out of the air flow path through the outlet opening passes upward through the stack and into the open environment, the stack and outlet opening being disposed above the fluid reservoir so that any fluid droplets that fall down within the stack collect within the fluid reservoir containing the wastewater from the oil or gas well, the stack having a height in a range of 2 meters to 5 meters above the roof; a plurality of spray nozzles positioned within the air flow path between the inlet opening and the outlet opening at spaced apart locations along a length of the air flow path, the spray nozzles spraying the fluid from the fluid reservoir upward into the air flow path; and a furnace disposed at the first end of the housing and blowing heated air through the inlet opening so that the heated air passes over the fluid reservoir, through the sprayed fluid and out of the housing through the tubular stack.
