Procedure Category Non Critical

PROCEDURE FILLING N2 GAS BOTTLES

01. Yakinkan ketersediaan level Nitrogen liquid di B atau C atau D -Storage vessel cukup untuk di isi ke botol – botol Gas N2.Yakinkan power supply untuk Pompa N2 Charging sudah tersedia.

02. Sambungkan selang/konektor-konektor ke Botol

N2 gas kosong yang sudah di inspeksi oleh pihak Technical.

03. Yakinkan sambungan-sambungan konektor tersebut sudah terikat dengan kuat.

04. Buka kerangan inlet Pompa V-1.

05. Tutup kerangan PV-019 atau V-4, dan kemudian buka V-448 atau V-648 dan V-698, atau V-703 dan V-727. Yakinkan V-5, V-6, V-7 dan V-9 harus dalam posisi tertutup. Kemudian buka kerangan V-2 .

06. Jalankan Pompa N2 Charging dengan cara menekan tombol start.

07. Lakukan venting beberapa saat dengan membuka V-8 hingga mengeluarkan cairan N2 melalui ujung venting.

08. Apabila cairan N2 sudah keluar melalui saluran venting Pompa, lalu tutup kembali V-8 dan buka sedikit V-3.

09. Tekanan discharge Pompa N2 sudah di Setting melalui PIC-01 pada tekanan 150 kg/cm2.

10. Lakukan venting beberapa saat melalui V-9, kemudian buka kerangan Vx sesuai jumlah botol yang akan di isi.Selanjutnya buka kerangan pada masing-masing kepala Botol N2 satu per-satu.

11. Amati kenaikan tekanan pada N2 Botol melalui pressure gauge.Apabila tekanan N2 di Botol mencapai 150 kg/cm2, Pompa N2 akan mati dengan sendirinya, atau Segera matikan pompa dan tutup kembali semua kerangan pada masing-masing kepala N2 Botol.

01. Assuring availability level of Nitrogen liquid in B or C or D -Storage vessel is enough for filling N2 Gas bottles.Assuring power supply to N2 Charging pump have been made available

02. Jointing hose/connector to emptied Bottle N2 gas had done inspect by Technical.

03. Assuring the extension connector have been trussed powerfully

04. Open inlet Pump valve V-1.

05. Close valve PV-019 or V-4, and than open V-448, or V-648 and V-698, or V-703 and V-727. Make sure that V-5, V-6, V-7 and V-9 must be close position. And then open V-2 .

06. Start N2 charging pump by push button start.

07. Do venting a few minutes with open valve V-8 through releasing dilution of N2 at venting line.

08. If dilution N2 have gone out through venting Pump line, close again V-8 and crack open V-3.

09. Discharge pressure N2 charging Pump have Setting in PIC-01 at pressure 150 kg/cm2.

10. Do venting a few moments through valve V-9, and then open valves Vx ,it’s equal with bottles to fill in . Hereinafter open valve of each head of N2 Bottles one by one.

11. Monitor increase of pressure at N2 Bottles at pressure gauge If pressure in N2 Bottles have reached 150 kg/cm2, N2 Pump will stop by itself, or Immediately stop N2 pump and close again all valves of each head of N2 Bottles.

12. Buang tekanan disepanjang header pengisian N2 botol melalui V-8 dan V-9 hingga habis.

13. Tutup kembali kerangan-kerangan V-1, V-2, V-3 dan Vx. Dan buka kembali kerangan PV-019 dan V-4. Kemudian lepaskan sambungan / konektor ke N2 botol.

14. Selesai.

12. Throw away pressure alongside header of admission filling of N2 bottles through V-8 and V-9 till empty.

13. Close valves V-1, V-2, V-3 and Vx. And back open valve PV-019 / V-4. And than disconnected extension of connector

N2 bottles.

14. Finished.
