Propane Storage And Export

General Project Description

The Total capacity of Phase 13 onshore facilities is 2000 MMSCFD of reservoir fluid. Phase 13 onshore Complex will include all processing units, utilities, offsite and infrastructure necessary to produce sales gas, gaseous ethane cut of petrochemical feedstock quality, commercial grade propane and butane for export and stabilized condensate. The complex is fed by the reservoir fluid delivered to the onshore plant (Tie-in) via two multiphase lines:

• Receiving facilities for HP separation of raw gas and condensate/water mixture.

• Condensate stabilization producing stabilized condensate for storage and export and light ends recycled in the HP gas system. One condensate flashing unit, normally not operated, is provided as a back-up of the stabilization facilities. Mercaptan is removed from condensate in the DMC unit.

• Gas treatment facilities producing sales gas, gaseous ethane and NGLs and consisting of:

• H2S removal from gas / CO2 partial removal from gas

• Dehydration unit, using molecular sieves technology

• Mercury guard

• Ethane extraction unit producing sales gas, gaseous ethane and NGLs

• NGL fractionation facilities to produce gaseous ethane and sour liquid butane and propane

• Gaseous ethane cut treatment for CO2 removal and drying for further export

• Propane and butane treatment for mercaptan removal and drying for further storage and export

• Export gas compression to export pipeline pressure MEG regeneration and injection unit including MRU

• Sulphur recovery, producing liquid Sulphur for further solidification and export

• Utilities, offsite required for operation
