Description
Fuel gas is a coproduct in the coal-based methanol to ethylene glycol production process, which can be used in areas such as household heating, gas stoves, water heaters, and power plants; this dataset includes environmental burdens associated with major raw and auxiliary materials, energy inputs, atmospheric emissions, and water discharges from the production process, but excludes infrastructure burdens such as production equipment, factory infrastructure construction, and equipment maintenance; the life cycle inventory was compiled from multiple data sources and optimized and modeled based on the best available information for 2022; the process flow for producing fuel gas from coal-based methanol involves coal powder gasification, purification, methanol synthesis, distillation, and olefin separation. Processes including hydrocarbons, olefin cracking for ethylene production, ethylene oxidation for ethylene oxide production, and ethylene oxide hydration for ethylene glycol production.

Process Description
Fuel gas is a gaseous mixture used as fuel, typically composed of various gases. It is a convenient and efficient form of energy widely utilized in residential, commercial, and industrial applications. Common fuel gases include natural gas and liquefied petroleum gas (LPG). Natural gas primarily consists of methane (CH4), a colorless and odorless gas that produces heat and water vapor when combusted. As a clean fuel, natural gas emits fewer pollutants during combustion and has a relatively low environmental impact. It is extensively used in residential heating, gas stoves, water heaters, and power generation stations.
