Oil-producing industry

Acrylamide polymers are used as multipurpose additives in the oil-producing industry. Introduction of polymers into drilling fluids-drilling muds improves the rheological properties of the fluids in question, positively affects the size of suspended particles, and adds to filterability of well preparation to operation. Another important function is soil structure formation, which imparts additional strength to the well walls. A positive effect is also observed in secondary oil production, where acrylamide polymers additives improve the mobility of aqueous brines injections, which contribute to... 

The production function is a large part of the oil-producing industry, and most of the same firms are dominant in both oil and gas. Exploration and drilling technologies for both oil and gas are essentially identical. Production from both oil well gas and gas... 

Items 1, 2, and 5 are units with a large number of applications within the oil-producing industry, while the others are at pilot unit level and will probably be installed commercially in the near future. 

In view of the laboratory and field experimental data obtained up to this time, as well as satisfactory results from several other commercial pilots presently under way, this process appears to hold promise to the oil producing industry as a means of increasing recovery, reducing production costs and increasing oil reserves. 

Fluorine reacts with the halogens and antimony to produce several compounds of commercial importance antimony pentafluoride [7783-70-2J, bromine trifluoride [7787-71 chlorine trifluoride [7790-91 -2J, and iodine pentafluoride [7783-66-6J. Chlorine trifluoride is used in the processing of UF (see Uraniumand uranium compounds). Bromine trifluoride is used in chemical cutting by the oil well industry (see Petroleum). Antimony and iodine pentafluorides are used as selective fluorinating agents to produce fluorochemical intermediates (see Fluorine compounds, inorganic). 

Petroleum refining, also called petroleum processing, is the recovery and/or generation of usable or salable fractions and products from cmde oil, either by distillation or by chemical reaction of the cmde oil constituents under the effects of heat and pressure. Synthetic cmde oil, produced from tar sand (oil sand) bitumen, and heavier oils are also used as feedstocks in some refineries. Heavy oil conversion (1), as practiced in many refineries, does not fall into the category of synthetic fuels (syncmde) production. In terms of Hquid fuels from coal and other carbonaceous feedstocks, such as oil shale (qv), the concept of a synthetic fuels industry has diminished over the past several years as being uneconomical in light of current petroleum prices. 

The increased availability of energy fueled the Industrial Revolution. The United States became the world s largest oil producer, and the new fossil fuels were abundant and modestly priced. A technology s energy efficiency was not a key part of capital investment decisions. Energy-efficient technology as a priority ranked well behind improved performance. 

Gas oil, which is heavier than kerosene, is the raw material of choice in cracking and other refinery operations. Cracking of gas oil produces a variety of fuels for automotive, industrial, and domestic (furnace) use. 

Following the war, there was a steady increase in imports into the United States relative to total supply. During this period, the U.S. share of world oil production declined from 60 percent to 40 percent (1959). Crude oil imports as a percentage of total crude oil going to refineries increased from about 5 percent to 12 percent and the U.S. industry for the first time shifted its position from a net exporter to a net importer of mineral oils. At the same time, U.S. companies were establishing a strong presence abroad. Indeed, much of the oil produced abroad and imported into the United States at that time was owned by American-based companies. 

Surfactants can be produced from both petrochemical resources and/or renewable, mostly oleochemical, feedstocks. Crude oil and natural gas make up the first class while palm oil (+kernel oil), tallow and coconut oil are the most relevant representatives of the group of renewable resources. Though the worldwide supplies of crude oil and natural gas are limited—estimated in 1996 at 131 X 1091 and 77 X 109 m3, respectively [28]—it is not expected that this will cause concern in the coming decades or even until the next century. In this respect it should be stressed that surfactant products only represent 1.5% of all petrochemical uses. Regarding the petrochemically derived raw materials, the main starting products comprise ethylene, n-paraffins and benzene obtained from crude oil by industrial processes such as distillation, cracking and adsorption/desorption. The primary products are subsequently converted to a series of intermediates like a-olefins, oxo-alcohols, primary alcohols, ethylene oxide and alkyl benzenes, which are then further modified to yield the desired surfactants. 

No. 2 fuel oil is a petroleum distillate that may be referred to as domestic fuel oil or industrial fuel oil. Domestic fuel oil is usually lighter and straight-run refined it is used primarily for home heating and to produce diesel fuel. Industrial distillate is the cracked type, or a blend of straight-run and cracked. It is used in smelting furnaces, ceramic kilns, and packaged boilers. 

Hydrocarbons are used as fuels and as the basic source of many other chemical compounds. The production of coke from coal also produces by-products known as coal-tars, which are used in the pharmaceutical, dye, food, and other industries. The refining of crude oil produces gasoline and many other fractions of the crude oil as well as petrochemical by-products. The range of useful products we derive from crude oil is very broad. These products not only power our automobiles, trucks, trains, and planes, but also provide the base for many of our medicines, foods, and numerous other essential products. (See the section of the book titled Atomic Structure for more on the chemistry of hydrocarbons.)... 

Production. Since citral is used in bulk as a starting material for the synthesis of vitamin A, it is produced industrially on a large scale. Smaller quantities are also isolated from essential oils. 

Orange peel oil is the major oil produced worldwide and is used extensively in the food industry, primarily as a flavouring in beverages and sweets. It possesses a light, sweet, fresh top note with fruity and aldehydic character. Many household and personal-care products employ orange oil owing to its pleasing... 

The essential oils produced by certain members of the widespread genus Salvia (Labiatae) are use extensively in the food and cosmetic industries. Examples are Dalmatian sage oil from S. officinalis (used... 

The use of terpenoids, usually as mixtures prepared from plants, dates from antiquity. The several essential oils produced by distillation of plant parts contained the plant essences. These oils have been employed in die preparation of perfumes, flavorings, and medidnals. Examples are oils of clove (local anesthetic in toothache), lemon (flavoring), lavender (perfume), and juniper (diuretic). Usually essential oil production depends on a simple technology which often involves steam distillation of plant material The perfume industry of Soudiem France uses somewhat more sophisticated procedures in the isolation of natural flower oils since these oils are heat sensitive. The separation of oils from citrus fruit residues m California and Florida is done by machine. 

Flax is grown mainly to produce linseed oil for industrial applications, Western Canada, China and India being leading producers. Other important areas of production are the Northern Plains of the USA (Maddock et al., 2005), Argentina, the former USSR and Uruguay. Flax is grown typically under dryland conditions. In Canada, flax is produced only as an industrial oilseed crop and not for textile use as in some countries.
