Line Sizing Calculation (Part 1)
1. DESIGN BASIS 1.1. Flow Rate, Temperature and Pressure Flow rate, pressure, and temperature for all process lines used for line sizing calculation will be taken from the material balance from Process Flow Diagram. 1.2. Line Sizing Criteria The criteria shown on Table 1 will be used to determine the line size. Such criteria are based on the engineering practice used to select the economic size of piping inside the plant battery limit. Items Criteria for Nominal Pipe Size Selection 1. Gas/Vapor Lines Pressure Drop (3) - D P per 100 m < 0.117 bar (P < 34.3 barg) - D P per 100 m 0.117-0.274 bar (34.3 < P < 137.2 barg) Velocity (1) -Velocity < 18.3 m/s 2. Liquid Lines For Continuous & Non Continuous Lines: - D P per 100 m < 0.9 bar (2) - Velocit...
