Buka lebar b.v suction 103-J.(CO2 + CO < 10 ppm ).

- Normalkan level OHT HP-LP 103-J. Naikkan rate gas 70 --> 80 % ( tabel lama ). - Naikkan tekanan HS ke 90 K. Start 103-J sesuai prosedure -Jalankan 120-J, jaga temp TI-5 = 8oC. -Continue drain casing compressor ( buang air ). - Purge dengan LS - 102-B - Naikkan tekanan discharge 103-J ke 95 K. - HCV-11 buka lebar dan isolir SP-35. Mulai press up loop via B/P MOV-1--> 30K/H. Buka lebar MOV-1. ( PI-221 = PI-80 ) -Jadikan HCV-11 = 5%, tutup LS purge 102-B -Buka lebar cock valve inlet 102-B. -Buka MOV-2 sampai flow FI-62 = 6-7 div. - Buka MIC-29 Start firing 102-B -Naikkan temp out syngas 102-B ke 450oC, dengan kenaikan bed katalis 105-D 50oC/H. Crack open chiller 125C,117C,118C,dan 119-C ( bila temp bed 105-D =300oC), perhatikan level flush drum dan kickback 105-J Produk NH3 Stop 120-J Atur quench MIC-13/14/15/16 sesuai figure temp bed 105-D. Naikkan rate gas ke 90 % Stop firing 102-B dan purge dengan LS Kirim purge gas ke PGRU-IV Tarik H2 dari PGRU-IV Sesuaikan rate gas/ produksi 100 % ( tabel baru ).
