Document Summary

It is often used to refine crude oil. Then, the vapor created is piped into the column, where the vapor cools as it rises. Various petroleum products (e. g. residue, diesel oil, kerosene, naphtha, petrol, and refinery gas) reconstitute from vapor to liquid at different temperatures. The point in time when the maximum rate of petroleum extraction is reached, after which the production rate is expected to enter terminal decline. Primary energy: energy that has not been subject to a conversion or a transformation process (e. g. coal, oil, natural gas, hydraulic, solar, wind, nuclear) Secondary energy: energy that has been subject to a conversion (e. g. electricity, fuel such as gasoline, kerosene, and heating oil) The left side of a sankey diagram tells us what the sources of energy are. Sources of energy listed on the diagram are solar, wind, hydro, biomass, geothermal, nuclear, coal, natural gas, and petroleum.
