Description
Crude hydrogen is an intermediate product in refining and chemical production; this dataset includes key raw materials, energy inputs, and waterborne emissions from the production process, but infrastructure such as production equipment and facility construction is excluded from the system boundary; the life cycle inventory is compiled from data sourced from multiple references; the crude hydrogen is generated in an ethane oxidative cracking process, which specifically includes steps such as ethane pyrolysis, cooling, separation, distillation, and hydrogen collection.
Activity Description
The crude hydrogen is generated in the ethane oxidative cracking process, which specifically includes procedures such as ethane thermal cracking, cooling, separation, distillation separation, and hydrogen collection.
Process Description
Crude hydrogen is a mixed gas produced during petroleum refining and chemical production processes, containing hydrogen and hydrocarbons. This mixed gas is typically generated from petroleum cracking or the processing of other hydrocarbon feedstocks. Crude hydrogen usually contains certain proportions of hydrocarbons such as ethylene, ethane, propane, and butane, as well as hydrogen. In petroleum refining and chemical production, crude hydrogen serves as an important intermediate product.
