Aviation turbine fuels are manufactured predominantly from straight-run kerosene or kerosene-naphtha blends in the case of wide-cut fuels that are produced from the atmospheric distillation of crude oil. Straight-run kerosene from low-sulfur (sweet) crude oil will meet all the requirements of the jet fuel specification without further refinery processing, but for the majority of feedstocks, the kerosene fraction will contain trace constituents that must be removed by hydrotreating (hydrofining) or by a chemical sweetening process (Speight, 2000). 

The problems of iron corrosion were already well known in antiquity for example, they were already highlighted in the Bible Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal [4]. In the oil extraction industry, corrosive attacks in pipelines for the transport of sweet crude oil extracted from high-pressure wells were... 

Accounts of early exploration and examination of the Athabasca deposit can be found elsewhere [3, 11-13] as can accounts of some of the early process development efforts [14-16], Commercial plants now mine oil sands and then extract bitumen using the hot water conditioning and flotation process (at production levels of over 300,000 bbl/d). The extracted bitumen is subsequently upgraded by refinery type processes to produce light, sweet crude oil. 

The toxicity of crude oil correlates with the relative content of l osoie, naphtha, and gasoline. Dosages of 48 ml/kg (sweet crude oil), 56 ml/kg (kerosene), or 74 ml/kg (sour crude oil) over the course of 1 week cause aspiration pneunonia ai, eventuiJIy, death.

Prepare a mixture of organic inhibitor with diesel oil or sweet crude oil in a separate mixing tank. The inhibitor-oil mixture can be varied from 1 6 to 1 13. 

Sour and sweet are terms referring to a crude oil s approximate sulfur content. In early days, these terms designated smell. A crude oil with a high sulfur content usually contains hydrogen sulfide—the gas associated with rotten eggs. Then the crude oil was called sour. Without this disagreeable odor, the crude oil was judged sweet. Today, the distinction between sour and sweet is based on total sulfur content. A sour crude oil is one with more than 0.5 wt % sulfur, whereas a sweet crude oil has 0.5 wt % or less sulfur. It has been estimated that 58 percent of U.S. crude oil reserves are sour. More important, an estimated 81 percent of world crude oil reserves are sour. ...
