PETROCHEMICAL SUPPLY CHAIN’S SHARE IN EMISSION OF GREEN HOUSE GASES, CASE STUDY: SHAZAND PETROCHEMICAL COMPLEX

Abstract

In this study petrochemical supply chain shares in global warming is studied by monitoring carbon footprint during manufacturing and distribution phase. For identification and measurement of carbon emissions in petrochemical supply chain, at first step necessary data are collected. Then carbon footprint is calculated in manufacturing process. So GHG is measured during fossil fuel use for chemical productions and electricity production in exclusive power plant in production phase. Also carbon emissions are calculated during chemical process (non-energy use of fossil fuels). The other activity that has an impact on GHG emissions is transportation. In this study Intergovernmental Panel for Climate Change (IPCC) methodology was employed. For conducting this research Shazand petrochemical complex in Iran is selected as a case study. The calculations and monitoring GHG will help to greening the petrochemical supply chain.The result shows GHG emissions in Shazad petrochemical complex supply chain is 6108960.35 tons per year. 6100434.9 tones CO2equ per year emit from manufacturing phase and 8525.4 tones CO2equ per year emit from distribution phase. Based on a comparison with statistics from United Nation Statistics division reports contribution of manufacturing phase of Shazand Petrochemical supply chain in global warming is about 0.020% and Based on a comparison with statistics from Iranian fuel Conservation Company and energy balance reports the contribution of distribution phase of Shazand Petrochemical supply chain in global warming is about 0.004%.
