Rev (a) Calculation Objective

1. To determine process and utility line sizes for Al-Jabalayn CPF plant.

(b) Assumptions

0 1. Primary guide to line sizing used was Reference 3. Reference 4 less conservative and less specific in general.

0 2. Whiile every effort was made to follow the guidelines (primarily Worley as Petrodar did not cover most situations) several pump suction lines in particular

0 were decided after negotiation with OGP in order to minimise changes in tank heights, tank levels in order to meet pump NPSHr requirements.0 3. Vendor data not included.

(c) References

0 1. Standard Calculation PR-CA-002 - Single Phase Pressure Drop0 2. Standard Calculation PR-CA-001 - Two Phase Pressure Drop

0 3. Ranhill Worley Design Standard - Line Sizing (086\00589-PR-DS-003)0 4. Specification for Piping design and Layout (PDOC-SP-PIP-002)
