Abstract

Dalam pemisahan minyak diseparator 3 fasa, untuk mendapatkan proses pemisahan yang sempurna dilakukan pengendalian proses, khususnya tekanan. Karena adanya proses pengendalian, maka perlu untuk adanya pengaman pada tekanan agar tidak terjadi bahaya selama prosesnya. Oleh karena itu, dilakukan pembuatan tugas akhir ini mengenai rancang bangun safety instrumented function untuk pressure pada separator 3 fasa. Sistem pengaman yang digunakan yaitu mode kontrol on-off (digital) dengan setpoint 25 psi (high pressure) dan 35 psi(highhigh pressure). Adapun instrumen yang digunakan yaitu mikrokontroler arduino uno, final element berupa Solenoid Valve Asco 8320G203 dan elemen transmisi, Pressure Transmitter Altronic Press. Sensor P/N 691201-1. Dari data yang diperoleh didapatkan penggolongan safety berdasarkan safety integrity level (SIL) yaitu SIL 1 dengan hasil perhitungan nilai pfd yaitu 0,00917321 (pressure transmitter), 0,0109 (mikro), 0,03406966 (psv) sehingga didapatkan pfd total yaitu 0,05414287 dengan gambar FTA (fault tree analysis) menggunakan OR. Dari hasil running sistem didapat nilai jarak antara waktu pembacaan dan bukaan valve dengan kepekaan pressure transmitter yang tinggi yaitu 0,38s. ================================================================================================================== In separation of oil in separator 3 phase, to get perfect separation needs control of process, especially pressure. Because of there are control process,so it’s impotant to install a safety accessory of pressure for minimize the danger. So that, this final project made about design and build safety instrumented function for separator 3 phase. Safety system which use is on-off contol mode (digital) with setpoint 25psi (high pressure) and 35psi (high-high pressure). The instruments which used are microcontroller arduino uno, Solenoid Valve Asco 8320G203 as final safety element, and transmition element, Pressure Transmitter Altronic Press. Sensor P/N 691201-1. From the data obtained safety classification obtained by the safety integrity level ( SIL ) is SIL 1 with the calculated value of the PFD is 0.00917321 (pressure transmitter),0.0109 ( micro ),0.03406966 ( psv ) to obtain the total PFD is 0,05414287 with the picture FTA (fault tree analysis) using OR. From this running system got the time value among pressure sensors and respons of valves with high sensitivity of pressure transmitter is 0,38s
