Application
Construction of three separators/concentrators for phosphoric acid.
This was an especially critical application, due to the constraints of heat generation during operation.
Characteristics
The separators are arranged vertically, with a Klöpper type lid and conical bottom of 45º. The principal diameter was fixed at Ø2500, giving a total capacity of 30m3.
They also have a supporting skirt for mounting.
PH Technology was responsible for both the mechanical design (conforming to code BS4994) and fabrication of the equipment.
Operating Conditions
The most critical design constraints for this equipment were the operating temperature of 80ºC, and the sharp difference between this and the temperature when it is stopped for cleaning, of up to 60ºC.
The design pressure was set at absolute vacuum.
The operating fluid was phosphoric acid at a concentration of 54%.
Material
The equipment was constructed with a bisphenol-A DERAKANE 411/350 vinylester epoxy resin based FRP throughout the laminate.
