Application
Construction of an effluent tank (for organic solvents) and a decomposer for sodium hypochlorite.
This was an especially critical application due to the corrossiveness of the medium.
Characteristics
The effluent tank was horizontal, Ø2400 in diameter, and had a total capacity of 20m3.
The hypochlorite decomposer was a vertical tank of Ø1200 diameter, with a total capacity of 2m3.
PH Technology was responsible for both the design and manufacture of the equipment.
Operating Conditions
The most critical condition for this equipment was the operating fluid.
In the case of the effluent tank this was a solution of sodium hypochlorite and organic solvents.
In the case of the hypochlorite decomposer it was HCl + NaCl + Cl2.
The design pressure was fixed at at 0.5 bar in both cases. The operating temperature was 60ºC for the effluent tank, and 100ºC for the decomposer.
Material
Both pieces of equipment were of dual composition construction, with a liner of ECTFE (Halar, a fluorinated thermoplastic) and a novolac vinylester epoxy resin based FRP structural reinforcement.
