A Study on a Carbon emission and Reduction Plan for the Construction Phase of a Natural Gas Plant

The estimation of carbon emission from a natural gas plant is performed with the recently ordered project of the plant in South Korea. The carbon emission coefficients suggested in the guideline by the Ministry of Land, Transport and Maritime Affairs in 2011, are used to calculate the carbon emission from all construction materials and the fuel consumption of construction machinery in the construction phase. To present a method for reducing the carbon emission, it is assumed that some portion of construction materials is replaced by industrial byproducts and construction waste recycling materials, and the amount of carbon reduction for the natural gas plant is analyzed. Also, the amount of carbon emission for producing recycled aggregate is analyzed through the data collected from 3 recycling companies. For the given natural plant, it is found that the major elements that generate most are construction materials and pipelines. And the recycling of industrial byproducts and construction waste recycling materials reduces carbon emission by 11%.
