Petroleum Liquid Feedstocks – Naphtha And Fuel Oil – Chemical Economics Handbook (CEH)

The first uses for naphtha and gas oil are the production of fuels, gasoline for naphtha, and diesel for gas oil. A secondary use for naphtha is as a feedstock for steam cracking to produce petrochemicals (ethylene, propylene) and the manufacturing of aromatic petrochemical products (benzene, toluene, and xylenes). Gas oil is used as a chemical feedstock for steam cracking, although usually much less preferred than naphtha and natural fuel liquids (NGLs, including liquefied petroleum gases).

Naphtha and gasoline oil refinery outputs rely on the composition of feed crude petroleum utilized and in flip the crude oil regional source. Crude oil extracted from Middle Eastern fields has totally different properties from that extracted in Alaska. Crude oils with an API gravity of 30° or more produce bigger amounts of products such as naphtha, kerosene, and light gasoline oils than these with an API gravity of lower than 30°. As well as, naphthenic crude oils have a tendency to provide comparatively higher portions of naphtha than the paraffinic crudes of the same specific gravity, which produce higher relative amounts of gasoline oils.

The next pie charts show world consumption of naphtha and gas oil in 2016.
Light naphtha consumption will enhance rapidly worldwide, except in North America, driven primarily by steam cracker feedstock demand. A lot of the demand development shall be in Southeast Asia, India, and the Center East. Consumption of gentle naphtha is also growing in North America, particularly Canada, as a diluent for heavy crude mixing, and considerably for direct mixing into gasoline and isomerization for octane Petroleum Equipment enhancement. In 2016, steam cracking accounted for a lot of the world consumption, followed by direct mixing into motor gasoline and isomerization.

Heavy naphtha consumption is forecast to extend at 1.6% yearly throughout 2016-21. Aromatics and gasoline production are brent crude oil price average the leading drivers for progress. As more heavy naphtha turns into obtainable from refineries, the exports development price will decline. In 2016, nearly all of heavy naphtha is used as reformer feed for production of aromatics and excessive-octane gasoline. Mixed with direct blending into motor gasoline, the percentage will increase much more.

Most heavy naphtha is used as reformer gasoline, break up between reforming for gasoline and reforming for aromatics. If one additionally considers direct mixing of motor gasoline, the ratio is skewed even more towards for gasoline manufacturing. Toluene, xylenes, and heavy aromatics that are produced in chemical reformers in excess of what is required to meet downstream chemical and solvent demand is brent crude oil price average blended into the gasoline pool as high-octane fuel parts.

The transportation sector accounted for almost 70% of fuel oil consumption, accounted for primarily by domestic transportation (motorcar consumption of diesel) and worldwide bunkers (primarily marine gasoline). Industrial (and commercial) utilization is the second-largest software for gasoline oil, with progress forecast at 1.2% annually during 2016-21. Industrial is often light heating oil for industrial and commercial makes use of. Transformation is the third-largest software, with consumption forecast to decline at 1.0% annually throughout 2016-21. Transformation processes include conversion of primary forms of power to secondary and further transformation to supply electricity or heat. Energy accounted for 1.5% of gas oil consumption, and is forecast to develop at 0.5% annually throughout 2016-21. Energy consists of use and losses by the vitality industry itself through the refinery course of. General fuel oil consumption is forecast to increase at 1.Four% per 12 months during 2016-21.
