ABSTRAKHidrogen sulfida merupakan gas beracun yang terkandung pada instalasi
produksi associated gas suatu industri eksplorasi minyak dan gas. Skripsi ini
merupakan penelitian deskriptif dengan pendekatan semi kuantitatif menggunakan
data sekunder perusahaan dan literature serta observasi lapangan yang kemudian
dianalisis menggunakan perangkat lunak Areal Location Hazardous Atmosphere
(ALOHA). Tujuan penelitian ini adalah mengetahui konsekuensi yang terjadi
berdasarkan jangkauan dispersi gas, dan populasi berisiko terpajan dari skenario
kebocoran instalasi produksi associated gas yang sudah dirancang.
Hasil penelitian ini didapatkan bahwa skenario worst case (ruptur dan
tidak terkendali) pada pipa gas berukuran 10 inch memiliki dispers gas paling
luas. Dalam satu jam, dispersi gas H2S terjauh dengan AEGL-1 0.51 ppm (60
min) mencapai 3.6 km dengan populasi berisiko mencakup penduduk yang tinggal
di sekitar area station produksi PT. X. Selain itu didapatkan gambaran
pengetahuan populasi berisiko terpanajan mengenai bahaya kebocoran gas serta
gambaran sistem keselamatan kebocoran gas yang tersedia di PT.X
ABSTRACTHydrogen sulfide is a toxic gas that is contained on the installation of
associated gas production of an oil and gas exploration industry. This thesis is a
descriptive study with a semi-quantitative approach using secondary data from the
company, literature and field observations. Then, these data are analyzed using the
software Areal Location of Hazardous Atmosphere (ALOHA). The purpose of
this study was to determine the consequences that occur based on the range of gas
dispersion, and population at risk to exposed of leakage scenarios that have been
designed at the associated gas production installations.
The results of this study found that the worst case scenario (uncontrolled
rupture) in a 10 inches gas pipeline has the most extensive gas dispersion. Within
an hour, the farthest H2S gas dispersion with AEGL-1 0.51 ppm (60 min) reached
3.6 km with a population at risk include people living in the surrounding area of
production station. Moreover, other results from this study were the level of
knowledge from population at risk about the dangers from gas leaks and gas leaks
safety systems overview that available in PT.X."
