2. External floating roof tank - Wikipedia

   en.wikipedia.org/wiki/External_floating_roof_tank

   The roof rises and falls with the liquid level in the tank. [1] As opposed to a fixed roof tank there is no vapor space in the floating roof tank (except for very low liquid level situations). In principle, this eliminates tank breathing loss and greatly reduces the evaporative loss of the stored liquid. There is a rim seal system between the ...

3. Storage tank - Wikipedia

   en.wikipedia.org/wiki/Storage_tank

   Some storage tanks need a floating roof in addition to or in lieu of the fixed roof and structure. This floating roof rises and falls with the liquid level inside the tank, thereby decreasing the vapour space above the liquid level. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries ...

4. Flotta oil terminal - Wikipedia

   en.wikipedia.org/wiki/Flotta_oil_terminal

   Phase 2, to accommodate the processing of oil from the Claymore field, was granted in summer 1976 and entailed additional plant and tanks. The cost of the Flotta terminal was about $240 million (1978 prices). [1] The total cost of the terminal and associated pipelines was estimated in 1984 to be $650 million (1984 prices). [2]

5. Ballcock - Wikipedia

   en.wikipedia.org/wiki/Ballcock

   Ballcock. A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y Ramírez, a Mexican priest and scientist, who described the device in ...

6. Dissolved air flotation - Wikipedia

   en.wikipedia.org/wiki/Dissolved_air_flotation

   Dissolved air flotation. Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.

7. Oil terminal - Wikipedia

   en.wikipedia.org/wiki/Oil_terminal

   The storage tanks at an oil terminal may include fixed roof tanks, internal floating roof tanks [10] and external floating roof tanks. [1] Floating roof tanks are generally used for more volatile products to reduce evaporation loss. Fixed roof tanks have a vapor space above the product, which breathes in or out as the product is removed or the ...

8. Combined sewer - Wikipedia

   en.wikipedia.org/wiki/Combined_sewer

   Combined sewer. A combined sewer system. During dry weather (and small storms), all flows are handled by the publicly owned treatment works (POTW). During large storms, the relief structure allows some of the combined stormwater and sewage to be discharged untreated to an adjacent water body. A combined sewer is a type of gravity sewer with a ...

   The trees in New York City reduce residential energy costs by $17.1 million a year, and to replace the trees in the city, it would cost an estimated $5.2 billion.
