| Use advice for data set | When using this LCA data set, ensure consideration of all relevant inputs such as raw materials, energy, electricity, steam, water, and auxiliary chemicals for the sub-stages involved in the production of syngas and propylene. Pay particular attention to the environmental burden allocation between the main product and by-products using the mass distribution method. The waste emissions of each process should also be included. Note that this evaluation does not cover the end-of-life treatment of products produced using propylene, as well as infrastructure and equipment maintenance. The functional unit of 4.82 tons should be used as a reference point for scaling data to larger or smaller production capacities as needed for your specific application. |
| Technical purpose of product or process | The syngas product from this process is a feedstock for industrial applications, including but not limited to the production of chemicals such as propylene via the coal to olefins route. The catalytic cracking process for olefins production at Sinopec Zhanjiang Dongxing Petrochemical Co., Ltd is specifically designed for the production of propylene, with a capacity of 116,000 tons annually, which can be utilized in a variety of chemical synthesis operations and manufacturing processes where propylene is a requisite raw material. |

| 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. |
