چکیده
Global interest in LNG products and supply chains is growing, demand continues to rise. As a clean energy source, can nevertheless emit air pollutants, albeit at lower level than transitional sources. An plant capable of producing up 126 MMTA was successfully developed simulated this study. A hybrid life cycle assessment model examine the social human health impacts chain’s environmental emission formation. The Multiregional Input–Output (MRIO) database, Aspen HYSYS model, Maritime Transportation Emission Quantification Tool are key sources information for extensive novel We began our research by grouping emissions according participation each stage chain. MDEA Sweetening plant, loading (export terminal), transportation stages were discovered have maximum emissions. midpoint data estimated stage’s CO2-eq, NOx-eq, PM2.5-eq per unit generated. According analysis results, terminal has most considerable normalized CO2-eq NOx-eq contribution across all chain stages. Furthermore, incredible intensity value recorded SRU TGTU units. Following impact findings calculated using ReCiPe 2016 characterization factors quantify daily loss associated with process units significant impact, followed terminal) about 7409.0 1203.9 (DALY/million Ton produced annually), respectively. Natural gas extraction NGL recovery fractionation lowest consequences.

Human health risk assessment of air emissions from development of unconventional natural gas resources.
BACKGROUND Technological advances (e.g. directional drilling, hydraulic fracturing), have led to increases in unconventional natural gas development (NGD), raising questions about health impacts. OBJECTIVES We estimated health risks for exposures to air emissions from a NGD project in Garfield County, Colorado with the objective of supporting risk prevention recommendations in a health impact...
متن کاملComparative life-cycle air emissions of coal, domestic natural gas, LNG, and SNG for electricity generation.
The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation....

This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...
