Basic Engineering Design of NGL-2300 and CFU-200 (C2+ Separation) Units
A) NGL-2300 (Ahwaz)
The purpose of the NGL-2300 plant is to maximize the recovery of C2+ components. The feed gas for this plant is sourced from:
- Separated gas from the 1st stage of the Maroon-Khami plant: 156 MMSCFD
- Gas condensate stabilization units of the Maroon-Khami plant: 18 MMSCFD
- Produced gas from the Maroon-5 production unit: 82 MMSCFD
The recovered C2+ condensates from this plant are transferred to the CFU-200 separation unit in Mahshahr, while the produced sweet gas is injected into the Maroon oil field. This plant comprises the following units:
- Low-pressure gas compression unit
- Gas sweetening unit
- Gas dehydration unit
- Acid gas compression unit
- C2+ recovery unit
- C2+ purification unit
- Utilities
- Pipelines for C2+ condensates, sweet gas, and acid gas
B) CFU-200 C2+ Separation Plant (Bandar Maah-Shahr)
The CFU-200 plant gathers C2+ components from NGL 2300 (mentioned above), NGL 1700, 1900, and 2000. In this plant, ethane, propane, butane, and C5+ components are recovered, stored, and transferred. This plant includes the following units:
- De-ethanizer
- De-propanizer
- De-butanizer
- Storage tanks for propane, butane, and C5+
- Transfer pumps
- Utilities
