Use advice for data set When using the dataset for Lifecycle Assessment, ensure that the system boundaries are consistent with the scope of the provided data, which includes only raw material and auxiliary inputs, energy and resource consumption, and waste emissions. The environmental impact of the end-of-life phase, infrastructure construction, and maintenance of equipment are not included in this model. Users should apply the mass allocation method accurately to apportion environmental burdens between propylene and its co-products, considering all relevant consumptions from sub-stages and waste emissions as outlined in the dataset.
Technical purpose of product or process Oxygen produced by air separation routes is typically employed for various industrial processes such as steelmaking, wastewater treatment, and medical applications. Propylene produced via the coal to olefins route is mainly utilized for manufacturing a wide range of plastic products and as an intermediate in the production of other chemicals. The case plant's capacity for producing propylene through catalytic cracking stands as a significant contribution to the commodity chemical industry.

Mathematical model
Model description The consumption of raw materials, energy, electricity, steam, water and auxiliary chemicals involved in each sub-stage is considered, and the output considers propylene and by-products (such as C4 products produced by the propane dehydrogenation process. The mass distribution method is used to quantify the products The environmental load between propylene and by-products. In addition, this model also considers the waste discharge of each process. This study focuses on the environmental impact analysis of different propylene production processes. Therefore, the utilization of propylene hydrocarbons and the end-of-life treatment of their products, as well as infrastructure Construction and equipment maintenance are outside the scope of this assessment.
