Create a process engineering calculation. Perform the calculations.
Use the applicable codes, standards, and guides applicable to the Oil and Gas Industry. Assume a placeholder value for any missing data, make an assumption (which shall be included in the inputs and assumptions section), and calculate. Use input valves from the following scope of work:
Make-up Water Tank, [] bbl capacity
1) Can pump NPSHr = [ ] m tank head required in boiling service, Non-can pumps NPSHr = [ ] m tank head in boiling service. Margin between NPSHr and NPSHa is assumed to be 1m).
2) LLL - Based on [ ] minutes LLL to LLLL operator intervention at the normal flow rate for the tank with no inflow.
3) NLL is estimated as [ ] of the distance between LLL and HLL.
4) HLL - Based on [ ] minutes HLL to HHLL operator intervention at the normal flow rate for the tank with no outflow.
5) HHLL - Based on [ ] feet from top seam of tank (6inches to top of overflow. 6 inches for instrument level control error and action. [ ] inches for overflow dia.)
6) Design flow rate based Scope of Work Document: 1) Design flow rate is PRELIMINARY based on 5% losses from [ ] m3/day estimated steam generator feed duty (to include blowdown and quality loss from Dec. 2011 design basis document).
Diameter = [ ] mm
Height = [ ] mm
LLLL = [ ] mm
LLL = [ ] mm
NLL = [ ] mm
HLL = [ ] mm
HHLL = [ ] mm
Design flow rate is [ ] m^3/hr
Determine the tank size
