Abstract

Industri petrokimia, khususnya pada produksi amonia di PT Petrokimia Gresik, beroperasi pada kondisi tekanan dan temperatur tinggi yang memiliki tingkat risiko signifikan.
Salah satu tahapan krusial dengan potensi bahaya tinggi adalah proses pemanasan awal menggunakan Start-up Heater 102-B untuk menaikkan temperatur gas sintesis sebelum
memasuki Ammonia Synthesis Converter 105-D. Meskipun tidak beroperasi secara kontinu, heater ini berhubungan langsung dengan bahan bakar gas (fuel gas) yang memicu risiko kebakaran, overheating pada coil, dan ledakan. Oleh karena itu, diperlukan sistem pengaman otomatis yang andal untuk menjamin keselamatan operasi instalasi pabrik. Studi ini bertujuan untuk menganalisis implementasi, fungsi proteksi, logika shutdown, serta arsitektur Safety Instrumented System (SIS) dan Burner Management System (BMS) yang terpasang pada Start up Heater 102-B. Hasil analisis menunjukkan bahwa sistem keselamatan pada Start-up Heater 102-B telah menerapkan prinsip fail-safe dengan konfigurasi Double block and bleed (DBB) pada jalur pipa bahan bakar. Untuk mencegah kegagalan operasi akibat kesalahan sensor tunggal. Selain itu, urutan kerja BMS mulai dari leak test hingga purging terbukti efektif mencegah akumulasi gas berbahaya di dalam ruang bakar. Secara keseluruhan, implementasi SIS dan BMS pada peralatan ini telah memenuhi standar keselamatan berlapis yang optimal.
=================================================================================================================================
The petrochemical industry—specifically regarding ammonia production at PT Petrokimia Gresik—operates under high-pressure and high-temperature conditions that entail significant risks. A critical stage involving high hazard potential is the preheating process using Start-up Heater 102-B, which raises the synthesis gas temperature before it enters the Ammonia Synthesis Converter 105-D. Although it does not operate continuously, this heater handles fuel gas, creating risks of fire, coil overheating, and explosion. Therefore, a reliable automatic safety system is essential to ensure the safe operation of the plant facility. This study aims to analyze the implementation, protection functions, shutdown logic, and architecture of the Safety Instrumented System (SIS) and Burner Management System (BMS) installed on Start-up Heater 102-B. The analysis reveals that the safety system for Start-up Heater 102-B incorporates fail-safe principles, utilizing a Double Block and Bleed (DBB) configuration on the fuel gas piping to prevent operational failure caused by a single sensor fault. Furthermore, the BMS operational sequence—ranging from leak testing to purging—has proven effective in preventing the accumulation of hazardous gases within the combustion chamber. Overall, the implementation of SIS and BMS on this equipment meets optimal multi-layered safety standards.
