The amount of individual products produced varies from month-to-month and year-to-year as refineries adjust production to meet market demand and to maximize profitability. Figure 1 Scheme of a РІР‚Вsolar refineryРІР‚в„ў for making fuels and chemicals from CO 2, H 2 O and sunlight On an industrial scale, one can visualize a solar refinery (see Figure 1) that converts readily available sources of carbon and hydrogen, in the form of CO 2 and water, to useful fuels, such as methanol, using energy sourced from a solar. A corn kernel is smaller and more dense than a popped kernel. This increase in volume is similar to what happens to popcorn when it is popped. refineries because of refinery processing gain. 42-gallon barrel of crude oil yields about 45 gallons of petroleum products in U.S. Learn more in Refining crude oil-inputs and outputsР”Р„ U.S. These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt. Products made from crude oilР”Р„fter crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. Petroleum products can also be made from coal, natural gas, and biomass. Petroleum products are fuels made from crude oil and hydrocarbons contained in natural gas.
