Description

Ethylene complex, by-product propylene and C4 When using this data for Life Cycle Assessment of ethylene production, it is important to allocate the environmental loads for co-produced substances (propylene and C4) correctly. The allocation should be based on the mass of the products, using the coefficients 0.54 for ethylene, 0.26 for propylene, and 0.19 for C4 derived from the inventory data. Additionally, as the CO2 emissions for the production of 1 ton of ethylene are provided, these data points should be incorporated appropriately into the LCA model considering the annual operating rate of the production line. Due to estimation errors in emission factors, results might require further normalization or validation with updated data.
