The velocity in the Amine process should be less than the following Mortar lining seal coat with paint 5.0 m/s.(2) Water piping: The maximum velocity should be less than the values given below, V e= C e/√ρ m, where, V e =Erosional velocity, ρ m=Homogeneous density, C e = Empirical constant normal in the range of 180-240. (1) The velocity above which erosion may occur in gas/liquid two-phase flow can be determined using the following empirical equation. The lines should be sized within the limitations tabulated below (see Table 1) Fluid Erosional Velocity Sonic Velocity Noise Velocity Minimum Velocity Flow pattern Special requirement Liquid-General Yes Yes Liquid-at boiling point Yes Yes Gas or vapor Yes Yes Gas/Liquid Yes Yes Steam condensate Yes Yes Slurry Yes Yes Yes Steam Yes Yes Table-1: (Limiting parameter) 3.3.1 Erosional Velocity formula used in Hydraulic calculation: Standard Pipe data 3.3 Limitation of Line Size:
