Petroleum products, such as gasoline, kerosene, home heating oil, residual fuel oil, and lubricating oils, come from one source – crude oil found below the earth’s surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25,000 feet into the earth’s interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those producing oil. Pressure at the source or pumping forces crude oil to the surface.

Crude oil wells flow at varying rates, from ten to thousands of barrels per hour. Petroleum products are always measured in 42-gallon barrels.

Petroleum products vary greatly in physical appearance: thin, thick, transparent or opaque, but regardless, their chemical composition is made up of only two elements: carbon and hydrogen, which form compounds called hydrocarbons. Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded. The combination of carbon and hydrogen forms many thousands of compounds which are possible because of the various positions and joinings of these two atoms in the hydrocarbon molecule

Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded. The combination of carbon and hydrogen forms many thousands of compounds which are possible because of the various positions and joinings of these two atoms in the hydrocarbon molecule. The various petroleum products are refined from the crude oil by heating and condensing the vapors. These products are the so-called light oils, such as gasoline, kerosene, and distillate oil. The residue remaining after the light oils are distilled is known as heavy or residual fuel oil and is used mostly for burning under boilers. Additional complicated refining processes rearrange the chemical structure of the hydrocarbons to produce other products, some of which are used to upgrade and increase the octane rating of various types of gasolines. Which of the following is not true? A. Crude oil is found below land and water. B. Crude oil is always found a few hundred feet below the surface. C. Pumping and pressure force crude oil to the surface. D. A variety of petroleum products is obtained from crude oil. Many thousands of hydrocarbon compounds are possible because A. the petroleum products vary greatly in physical appearance B. complicated refining processes rearrange the chemical structure C. the two atoms in the molecule assume many positions D. the pressure needed to force it to the surface causes molecular transformation Which of the following is true? A. The various petroleum products are produced by filtration. B. Heating and condensation produce the various products. C. Chemical separation is used to produce the various products. D.

East Somalia’s prolonged shortage of rain, which has already caused food supplies to fail and brought unemployment in farming areas, could also affect the production of electricity, and thus reduce the output from the nation’s mines. The mining industry and especially copper mining, uses a huge amount of electricity and is almost completely dependent on the government’s Electricity Supply Commission. But the Commission has recently asked the mines what would happen if electricity supplies were reduced by ten, twenty or thirty per cent. The Commission’s power stations, which produce the electricity using coal as fuel, are mostly situated near the large coal fields of Eastern Province. But this area has little water so the cooling towers at the power stations have to be supplied with water from elsewhere. The problem now is that water levels in all rivers and lakes have fallen dangerously low and, in some cases are well below the intake pipes which feed into the pipelines which supply the cooling towers. In a desperate attempt to solve the problem, engineers are spending some forty million dollars on building a series of small dams across the Haro river. It is hoped that these dams will make the water level at the Malawa Dam rise so that water can then be pumped through a new pipeline to the power stations. This will take time and it is now the dry season. Very little rain falls before October or November, and, after a shortage which has lasted for four years and is believed to be the worst in two centuries, nobody can say whether the rains will be sufficient. The amount of electricity and water used by the mines has tended to increase in recent years. The mines, which produce about half the country’s export earnings, need electricity in order to pump fresh air through their workings and to drive machines which crush vast quantities of rock. Each mine also has to provide accommodation for as many as three thousand workers. How might West Somalia’s lack of rain affect electricity supplies and mining? A. Copper mines are having to use less electricity. B. Coal supplies are failing to reach power stations. C. Electricity supplies to mines may he cut by up to thirty per cent. D. Copper mines may be unable to pump water by October. Where does the Electricity Supply Commission produce most of its electric its? A. Along the Haro River B. Near the copper mines C. At the Malawa Dam D. In Eastern Province The action that the engineers are taking A. may not help if there is sufficient rain B. will become effective towards the end of the year C. should get enough water to the mines D. will use up a lot of electricity The engineers aim to A. change the direction of the Haro river B. keep more water at the Malawa Dam C. get more water into the Haro riv
