10. Separation System Scrubbers - 2 phase separation, to recover liquid carried over from production separator or due to condensation Liquid loading smaller. Application: upstream of mechanical equipment like compressors. Normally vertical Filter separators - designed to remove solid and liquid mists particles less than 10 micron

11. Vortex breaker – To stop funneling action, to prevent gas from escaping. Foaming - causes less efficient separation. To add anti foam agent. Critical velocity - cannot be exceeded, otherwise droplets of liquid in gas do not have the time to drop out. Residence time not enough - vapor bubble has no time to rise from the liquid-vapor interface

12. For large volume of production, normally two or more parallel trains of separation. Avoid full shutdown for repair or maintenance Test separators - periodic measurement for a single well, discharged back to common streams.

13. Gas Handling The gas which is naturally produced or separated from the oil may not be transported by pipeline for sales. Other applications of natural gas: 1.Injected back into the reservoir to help maintain pressure. 2.Assist wells to flow known as gas lift. 3.Fuel gas.

15. Back up

17. This method is using the engineering formula to reconfirm the method 1. Given Q= 38.5 kbd and V= 6 ft/s. Using formula below: d = (0.012Q/V) 1/2 d = (0.012 x 38 500 / 6) 1/2 d = 8.77 inch Percentage error For 10 inch pipeline size Percentage error (%) = (10 – 8.77)/8.77 x 100 = 14.02 % For 8 inch pipeline size Percentage error (%) = (8.77 – 8)/8.77 x 100 = 8.77 %
