Indonesia is a country with a population of 270 million as of 2020 which thus requires a substantial amount of energy to support growth and development. Over the last 5 years from 2012 to 2017 natural gas production averaged 2.9 trillion standard cubic feet (Tscf) making natural gas the third primary source of energy used in Indonesia after oil and coal. With its significant use as an energy source in Indonesia natural gas has significant impacts on the environment such as global warming potential (GWP) during its lifetime. Thus the study aims to evaluate the potential environmental impact per 1 MMscf of natural gas produced using the life cycle assessment method based on ISO 14040/14044 standards and investigate the most contributed impact categories and unit process to the overall impact using Principal Component Analysis (PCA). The target of the study is an offshore natural gas production site located on Makassar Strait South Kalimantan Province Indonesia. On the basis of the 2019 research data the results of impact assessment are as follows: Abiotic Resource Depletion (ARD): 1.1 E06 MJ/MMscf Acidification Potential (AP): 1.1 E00 kg SO2 eq./MMscf Eutrophication Potential (EP): 2.5 E01 kg PO4 3 eq./MMscf Fresh Water Ecotoxicity Potential (FAETP): 8.0 E05 kg 1 4-DCB eq./MMscf Global Warming Potential (GWP): 1.1 E03 kg CO2 eq./MMscf Human Toxicity (HT): 3.5 E00kg 1 4-DCB eq./MMscf Marine Aquatic Ecotoxicity Potential (MAETP): 3.8 E03 kg 1 4-DCB eq./MMscf Photochemical Oxidant Potential (POP): 6.0 E02 kg ethylene eq./MMscf and Terrestrial Ecotoxicity Potential (TETP): 9.0 E02 kg 1 4-DCB eq./MMscf.

Abstract

Indonesia is a country with a population of 270 million as of 2020 which thus requires a substantial amount of energy to support growth and development. Over the last 5 years from 2012 to 2017 natural gas production averaged 2.9 trillion standard cubic feet (Tscf) making natural gas the third primary source of energy used in Indonesia after oil and coal. With its significant use as an energy source in Indonesia natural gas has significant impacts on the environment such as global warming potential (GWP) during its lifetime. Thus the study aims to evaluate the potential environmental impact per 1 MMscf of natural gas produced using the life cycle assessment method based on ISO 14040/14044 standards and investigate the most contributed impact categories and unit process to the overall impact using Principal Component Analysis (PCA). The target of the study is an offshore natural gas production site located on Makassar Strait South Kalimantan Province Indonesia. On the basis of the 2019 research data the results of impact assessment are as follows: Abiotic Resource Depletion (ARD): 1.1 E06 MJ/MMscf Acidification Potential (AP): 1.1 E00 kg SO2 eq./MMscf Eutrophication Potential (EP): 2.5 E01 kg PO4 3 eq./MMscf Fresh Water Ecotoxicity Potential (FAETP): 8.0 E05 kg 1 4-DCB eq./MMscf Global Warming Potential (GWP): 1.1 E03 kg CO2 eq./MMscf Human Toxicity (HT): 3.5 E00kg 1 4-DCB eq./MMscf Marine Aquatic Ecotoxicity Potential (MAETP): 3.8 E03 kg 1 4-DCB eq./MMscf Photochemical Oxidant Potential (POP): 6.0 E02 kg ethylene eq./MMscf and Terrestrial Ecotoxicity Potential (TETP): 9.0 E02 kg 1 4-DCB eq./MMscf. After normalisation and PCA most contributed impact categories are grouped with the first group of AP EP GWP POP and HT which are associated with gas compressor unit and the second one is FAETP MAETP TETP and also HT which are associated with produced water treatment unit.
