化工廠內溫室氣體排放量評估與減量策略

自1997年京都會議後，全球先進國家均研擬因應溫室氣體減量的方向與措施。近年來全球各國已建立了溫室氣體排放管制的共識，該化工廠因應國家減碳策略，並於2015年度起推動溫室氣體盤查作業，建立該廠溫室氣體盤查管理制度，以求達成二氧化碳排放減量之目標。故本研究旨為透過溫室氣體盤查確實掌握溫室氣體排放狀況，進而研議、提出可行之溫室氣體減量方案，並確實執行減量計畫工作。本研究估算排放源之排放量將利用監測儀器直接量測、排放係數及質量平衡等方法間接求出。本研究溫室氣體排放源鑑別表中屬生產製造作業程序之排放源最多，該類所屬的溫室氣體排放源約佔全部的三分之二，其所產生之溫室氣體排放種類大致為CO2、CH4及N2O。全廠製程所使用天然氣排放源為最主要排放貢獻，其次為外購電力排放源及使用混合微硫燃油排放源，其皆來自於能源使用或燃料燃燒之製造活動，由此可見化石燃料燃燒對全球暖化之衝擊影響最大。間接排放源溫室氣體排放量以電力使用所致總排放量比例高達81.83%，其主要原因為年度使用量甚大，未來仍需針對此項溫室氣體排放量加以評估並妥善控管。

Since the Kyoto Conference in 1997, advanced countries around the world have developed directions and measures to respond to greenhouse gas reductions. In recent years, countries around the world have established a consensus on greenhouse gas emission control. In response to the national carbon reduction strategy, the chemical plant will promote greenhouse gas inventory operations in 2015 and establish a greenhouse gas inventory management system to achieve carbon dioxide emission reduction. aims. Therefore, the purpose of this study is to conduct a greenhouse gas emission check through greenhouse gas inventory, and then to propose and propose a feasible greenhouse gas reduction plan, and indeed implement the reduction plan. This study estimates that emissions from sources will be indirectly determined using methods such as direct measurement of monitoring instruments, emission factors, and mass balance. In this study, the greenhouse gas emission source identification table has the largest number of emission sources, and the greenhouse gas emission sources of this category account for about two-thirds of the total. The greenhouse gas emission types generated by the research are roughly CO2, CH4 and N2O. The natural gas emission source used in the whole plant process contributes to the most important emissions, followed by the purchased electricity emission source and the use of mixed micro-sulfur fuel emission sources, all from the manufacturing activities of energy use or fuel combustion, from which the fossil fuel combustion pair can be seen. The impact of global warming has the greatest impact. The proportion of total emissions from indirect emission sources of greenhouse gases to electricity use is as high as 81.83%. The main reason for this is that the annual use is very large, and it is still necessary to evaluate and properly control this greenhouse gas emissions in the future.
