A short history of gas oil
Around 1912, U.S. demand for gas oil began to exceed the amount resulting from refinery crude- gas oil runs geared to the demand for kerosene, fuel oils, etc. Since then, the gas oil industry's biggest single problem has been devising new ways to meet the tremendous demand for gas oil without, at the same time, overproducing other gas oil products. Thus, it has devoted great time and effort to the development of processes for increasing the gas oil yield obtainable from crude oil. Simultaneously, in order to satisfy the gas oil -quantity requirements resulting from continual progress in engine design, the industry also has has to develop other processes for improving gas oil properties, even, if necessary, at the expense of yield. In achieving both of these somewhat conflicting goals, refiners have advanced gas oil manufacture from the status of a relatively simple art to one of the world's most complex and efficient technologies.
The processes by which they produce today's high-octane gas oil are described below. Gas oil refining begins with the distillation of crude oil into fractions of different boiling ranges. The crude oil is heated to 370 degrees to 470 degrees Celsius, pumped into a fractioning tower, and separated into the following major fractions. Because they are naturally occurring fractions of crude oil, the naphtha fractions obtained by distillation are called virgin naphtha, or straight run gas oil. Both the amounts of these naphthas and their hydrocarbon compositions depend on the type of crude oil being distilled. Thus, straight run gas oils differ widely in such properties as specific gravity, vaporization characteristics, and antiknock quality. The light naphtha fraction is usually of sufficiently high ON to be used as a component of finished gasoline without any more refining than is needed to remove undesirable impurities. The heavy naphtha is catalytically reformed to higher-octane blending stock. The kerosene and light gas oil fractions, referred to collectively as middle distillates, are used in the production of kerosene, jet fuel, gas oil fuel, and furnace oils. The heavy gas oil fraction may be used in heavy gas oil fuel, industrial fuel oil, and bunker oil. However, in the United States, gas oil demand is so high that much of the heavy gas oil and other heavy oils recovered from the reduced crude are cracked into gas oils by processes described below.
Since natural gas oil (also called casing head gas oil) is a highly volatile mixture of light hydrocarbons, only a limited amount of it can be included in finished gas oil without exceeding desired volatility characteristics. Moreover, antiknock quality of natural gas oil is relatively low since it contains a large amount of straight-chain paraffinic hydrocarbons. Early in the history of petroleum refining, it was found that higher-boiling hydrocarbons could be broken down, or cracked, into lower-boiling ones by subjecting them to high temperatures for an appreciable length of time. In fact, a form of cracking was used as early as 1869 to convert heavier crude-oil fractions into kerosene. Use of cracking to produce gas oil began in 1913 and grew rapidly as the nation's motor-vehicle population multiplied. Cracking in the presence of hydrogen, has recently been gaining favor as a highly flexible refining process because it permits wide variations in yields of gas oil and furnace oils to meet seasonal demand changes. With hydrocracking, refiners can convert heavy fractions into maximum amounts of gas oil and only small amounts of furnace oil, or vice versa, as needed. Moreover, hydrocracking is particularly effective in processing highly refractory (hard-to-crack) stocks. Thus,the process enables refiners to convert practically worthless heavy cracked stocks into gas oil, fuel oil, or other highly salable products.
All reforming processes have the same general purpose: to convert low-octane gas oil-range hydrocarbons into higher-octane ones. Reforming is largely limited to the upgrading of heavier gas oil fractions, such as straight run stocks boiling from 90 to 200 degrees Celsius, because lighter fractions do not contain substantial amounts of hydrocarbons suitable for reforming. Only about 80 percent of the feedstock volume processed is recovered as full- boiling-range gas oil, because the cracking reactions produce substantial amounts of gases.
Unlike cracking, alkylation makes larger hydrocarbons from smaller ones; it produces gas oil-range liquids from refinery gases. Because of its cost, however, its major value stems from the exceptionally high antiknock quality of its product, rather than from the fact that it offers another way to make gas oil. Extensive use of alkylation began during World War II to produce the high-octane (100+) gas oils required by military aircraft. After the war, some alkylation units not required to meet the demand for aviation gas oil were operated to make highly desirable blending stocks for passenger-car gas oil. And more recently, a number of refiners have installed new units exclusively for such use.
