Low-pressure steam refers to steam with a pressure of below 2.5 MPa and temperature not exceeding 400 °C; this low-pressure steam is a by-product of the following processes: "activated coke, anthracite, for flue gas desulfurization and denitrification", "methanol, coke oven gas", "liquid ammonia, produced from residue oil", "liquid ammonia, coal-based", and "hydrochloric acid, direct synthesis method". The production activity of this product represents the arithmetic average of these processes. If the specific manufacturing process of the low-pressure steam cannot be clearly identified, this dataset can be used. Detailed technical descriptions, system boundaries, and related information can be referenced from various life cycle datasets on low-pressure steam production. Infrastructure such as production equipment manufacturing and facility construction is not included within the dataset boundary.
