NOTES

40 41 1. * Indicates SUPPLIER to furnish, confirm and specify data 42 2. Fluid is a combination between Oil, Condensate and Water 43 3. Heater Operating Mode is parallel 2 X 50%. All flowrate, power and duty data is total flow/duty for both heaters 44 4. Maximum allowable pressure drop is 10 psi. SUPPILER to confirm the same 45 5.It is assume that pressure drop at Heater is at maximum allowable pressure drop. 46 6. Process / thermal design, sizing, mechanical performance guarantee of Condensate heater is SUPPLIER's responsibility. 47 7. Electric heater along with vessel shall be inspected and certified by MIGAS. SUPPLIER shall be responsible to submit necessary 48

documentation / drawings required for MIGAS certification.

49 8.ANSI K (dual) type thermocouples shall form SUPPLIER's scope of supply. 50 9. Power supply available at PURCHASER's battery limit is 6 kV, 60 Hz, 3 ph for medium voltage and 480 V, 3 ph, 60 Hz for low voltage. 51 10. 10% spare heating elements shall be provided for electric heater. 52 11. Condensate Heater shall be supplied with thyristor control panel suitable for the intended service and continuous modulating control. 53 12. Dimensional details (LxWxH) along with heat dissipation quantity for thyristor control panel shall be submitted along with proposal. 54 13. SUPPLIER to advise minimum turndown as well as pressure drop across heater vessel during dirty and clean conditions 55 14. SUPPLIER shall identify the requirement of anti-condensate heater if any. If required the same shall be supplied and installed. 56 15. SUPPLIER shall refer Equipment and piping insulation spec. 84501-9200-1L-008 for more details 57 16. Fluid Composition is attached on page 3. 58 17. The heater to be analyised during the design phase to ensure that accoustic or flow induced vibration will not occur 59 18. Vendor shall supply suitable and sufficient support to prevent bending of heater elements and flow induced vibration 60 19. Vendor is required to demonstrate either by calculation or by field evidence that heater element is desinged and constructed to provide estimated time to 61

failure of 25 years for the heater elements

62 20. The noise level measured at one metre distance fromt the heater panel, at any position shall not exceed 70 dB at any load. 63 21. Vendor to mention TYPE of Exchanger 64 22. which is designed to minimize peak inrush current 65 23. Electric Heater packages shall have a continous use design life of 25 years. 66 67 68 69 70
