| Use advice for data set | Users of this LCA dataset for paraxylene production should note that we considered the waste flows from production processes but excluded the environmental burdens of waste disposals (e.g., incineration), factory infrastructure construction, and equipment maintenance from the scope of analysis. |
| Technical purpose of product or process | As a basic chemical material, ethylene glycol is crucial to its downstream economic industries of polyester, textile and apparel, packaging materials, electronic appliances. |

| General comment on data set | The objective of the LCA model in this study is to quantitatively assess the environmental loads of ethylene glycol produced by OEG. The functional unit of the LCA model is defined as making one ton of ethylene glycol product with a purity of 99.9% in weight. The system boundary of ethylene glycol production was defined as "cradle to gate". The LCA was performed by the attributional method that assigns the specific environmental impacts to its functional unit. The specific processes include ethylene production by cracking naphtha as raw material, followed by ethylene oxide, which is finally converted to ethylene glycol product by hydration. |

| Model description | Feedstocks of coal, naphtha and ethane come from varied market sources. Therefore, we excluded the environmental burdens of raw materials transportation to lower the uncertainties. |
