Ethylene oxide is an important raw material for synthesizing chemical products such as polyethers, glycols, polyether alcohols, resins, and surfactants. This dataset includes main raw materials, auxiliary materials, energy, and water emissions from the production process; infrastructure such as production equipment and factory construction is not included within the system boundaries of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The production process of ethylene oxide includes steps such as raw material preparation, chlorination, saponification, and crude and fine distillation.
