Objective :
1. Sizing of pump is performed to determine the following:
a) Available NPSH
b) Suction Head
c) Discharge Head
d) Differential Head
e) Shaft Absorbed Power
Basis And Assumptions :
1. Pump is designed to operate at 2 x 100% design criteria.
2. Pump Capacity is m3/hr.
3. The pump sizing properties are based on HP Header/Test Header PSV Blocked Discharge at atmospheric condition and the temperature of 59°C
(assume heater operation in the closed drain vessel).
4. Suction vessel (Closed Drain Vessel) Operating Pressure / Temperature = kPag @ oC
5. Discharge Facility (Common Production Header) Operating Pressure = kPag (Max Operating without margin based on
6. Liquid properties are outlined below : PCVL in-house OLGA study for pipeline
Density = kg/m3 hydraulics).
Viscosity = cP
Vapour Pressure = kPa
Temperature = oC
7. 30 % margin added on piping length as line routing is not confirmed.
8. Pump efficiency is assumed at 50 %.
9. Closed Drain Drum is considered to be horizontal and having boot. The vertical distance between boot tangent line to pump centerline is is 2.305 m.
as per latest PDMS model. Meanwhile all the pumps stop at 0.65 m from bottom of boot.
10. It is assumed that height available between pump discharge to the Common Prod Header Unit is (+) m
11. It is assumed that distance available between pump discharge to the Common Prod Header is (+) m

Summary of Results :
1. Available NPSH = m liquid
2. Suction Pressure = kPa (a)
3. Discharge Pressure = kPa (a)
4. Differential Pressure = kPa
