4. REFRIGERANT PACKAGE

• Penambahan refrigerant package diperlukan karena adanya kenaikan temparature operasi dari sumur-sumur yang ada di Merbau

• Refrigerant package dibangun dengan tujuan untuk memaksimalkan operasional dari plant Merbau

• Refrigerant package dapat dioperasikan maksimum pada temperature 146 ºF dengan flow 85 mmscfd

• Temperature gas dari sumur bisa diturunkan dengan refrigerant package sampai dengan 60 ºF

PERALATAN UTAMA REFRIGERANT PACKAGE

• Gas-gas Recuperative (HE-33-201R)• Evaporator (HE-33-202R)• Compressor (K-33-208R A/B/C)• Condenser (AFC-33-208R A/B/C/D)• Liquid Receiver (V-33-210R)
