At the Fractionation Plant, NGL will be purified through De-Propanizer chamber to become Pure Propane (C3) and De-Butanizer chamber to become Butane (C4) and then mixed by static mixers, known as Mixed Liquid Petroleum Gas (Mixed LPG) stored in the storage tank 2×1.000 MT and 2×2.000 MT capacity and Condensate (C5+) are stored in a storage tank with capacity of 25,000 Barrel and transferred through a 1.2 km long pipeline to the ship unloading facility at the existing dock and 4,2 km long Mix LPG pipeline to Pulau Layang (Gasdom) for stocking needs of Southern Sumatra (Palembang, Jambi, Bengkulu, Lampung, Bangka Belitung). At the Fractionation Plant in Banyuasin, certain utilities system such as electricity supplied by Refinery Unit III PT Pertamina (Persero) with a capacity of 900 kW equipped with two (2) units of 6.6 kV transformers. Products from the LPG refinery is mixed LPG. NGL is processed through the De-Propanizer and De-Butanizer column to be a pure Propane (C3) and Butane (C4). Mixed LPG then kept stored in the storage tank 2×1.000 MT and 2×2.000 MT capacity, while condensate (C5+) are stored in a condensate storage tank 25,000 Barrel capacity. The LPG products are transferred through a 1.2 kilometer long pipeline in the Jetty – 1 to be sent outside Palembang, while for Palembang demands sent through 4.2 km pipelines to Pulau Layang (Gasdom), for Palembang, Jambi, Bengkulu, Lampung and Bangka Belitung.

The Extraction facilities located in West Prabumulih is designed to extract the optimum amount of NGL from the combination of source gas at a capacity of 250 MMSCFD that available in Gas Compression Station 10 (SKG-10) in West Prabumulih. The NGL extraction plant, provide the means to extract NGL from gas pipeline. Extraction lean (residue) Methane gas (C1) and Ethane (C2) with the De-Ethanizer returned to the metering gas station and NGL extraction (Propane/C3, Butane/C4, Condensate/C5+) are transferred to the Fractionation plant that located in Refinery Unit III Pertamina Plaju/ Sungai Gerong, Banyuasin. NGL pipeline size 8 inches installed around 89.6 km long to transport NGL from Extraction Plant to Factionation Plant. NGL Extraction Plant in Prabumulih is designed to be self-sufficient by necessity in the provision of all utility systems, one and only across the line system, being feed gas supplier, back to lean gas, NGL pipelines and fuel gas track, and has gas power generator facilities with capacity of 3×725 kW and 1 unit emergency diesel generator with a capacity of 537 kW. NGL Extraction Plant in Prabumulih located next to PEP-SBSa�� gas metering station SKG-10, provides facilities to extract NGL from gas pipeline from PEP gas field in South Sumatra. The exhaust Methane (C1) and Ethane (C2) gases that is not drawn through De-Ethanizer process returned as a gas to gas metering station, whereas Propane/C3, Butane/C4, Condensate/C5+ is transferred to the Fractionation Refinery located in Refinery Unit III Sungai Gerong in Palembang by NGL pipelines size 8 inches A� 90 km long.
