초록

Fossil fuel depletion and global warming have encouraged to develop new technologies to producepetrochemicals from alternative sources while reducing greenhouse gas (GHG) emission. Moreover, as the quantitativeverification of GHG reduction potential of technologies under development is greatly required, much interest has beendeveloped in GHG emission accounting. This work assessed the greenhouse gas (GHG) reduction potential of ethyleneproduction using Lintz-Donawiz converter gas (LDG) from steelmaking industry and hydrogen gas. We developed twoscenarios based on the GHG accounting methodology used in GHG emission trading system: reduction potentials on theorganizational boundaries of steelmaking and petrochemical industries respectively and comprehensive reductionpotential on the national level. Steelmaking company (LDG supplier) is able to reduce carbon dioxide emission to 31% ofbaseline emission by substituting LDG for natural gas, which has the lower carbon content than the by-product gas, inpower generation plant. In petrochemical company (LDG consumer), GHG reduction isn’t achieved since the developedethylene production process generates more GHG compared to conventional naphtha steam cracking process. However,it is mostly due to the transport of greenhouse gas (i.e., CO2) in LDG from steelmaking company boundary topetrochemical company boundary. In conclusion, overall GHG reduction potential on the national level is 1,083,519 tCO2eqwhich is 8 tCO2/tEthylene by introducing this ethylene production process.
