Sugar refineries are projected.
Manufacturing industry is confined to a few articles and commodities, such as cement, tea, tin cans (for oil), cotton goods, oil refineries, tobacco factories, flour-mills, silk-winding mills (especially at Shusha and Jebrail in the south of Elisavetpol), distilleries and breweries.
Two large refineries, one on Newtown Creek, Long Island, and another in South Brooklyn, also on Long Island, were in successful operation when the abundant pr oduction of petroleum, which immediately followed the completion of the Drake well, placed at the disposal of the refiner a material which could be worked more profitably than bituminous shale.
The existing refineries were accordingly altered so as to adapt them for the refining of petroleum; but in the manufacture of burning oil from petroleum the small stills which had been in use in the distillation of shale-oil were at first employed.
In the earlier refineries the stills, the capacity of which varied from 25 to 80 barrels, usually consisted of a vertical cylinder, constructed of castor wrought-iron, with a boiler-plate bottom and a cast-iron dome, on which the " goose-neck " was bolted.
In the American petroleum refineries it is found that sufficient cracking can be produced by slow distillation in stills of which the upper part is sufficiently cool to allow of the condensation of the vapours of the less volatile hydrocarbons, the condensed liquid thus falling back into the heated body of oil.
It is now rarely practised, although in some refineries both the nitric acid and the sulphuric acid processes are combined, the alloy being first treated with nitric acid.
Czechoslovakia manufactures and exports agricultural machinery, plant for sugar refineries and distilleries, locomotives, railway carriages and trucks and other rolling-stock, motor-cars, tractors.
The leading industry of Udine is silk-spinning, but it also possesses manufactures of linen, cotton, hats and paper, tanneries and sugar refineries, and has a considerable trade in flax, hemp, &c. Branch railways lead to Cividale del Friuli and S.
Besides the petroleum refineries the town possesses oil-works (for fuel), flour-mills, sulphuric acid works and tobacco factories.
Meissen also contains iron foundries, factories for making earthenware stoves and pottery, sugar refineries, breweries and tanneries.
There are several large tobacco factories, flour mills, boot factories, sugar refineries, tanneries, tallow works, meat-preserving, glue and kerosene-oil factories and soap works.
Other principal branches of industry are: tobacco manufactories, belonging to the state, tobacco being a government monopoly; iron foundries, mostly in the mining region; agricultural machinery and implements, notably at Budapest; leather manufactures; paper-mills, the largest at Fiume; glass (only the more common sort) and earthenwares; chemicals; wooden products; petroleum-refineries; woollen yarns and cloth manufactories, as well as several establishments of knitting and weaving.
Brewing, distilling, cooperage, iron-founding, hatmaking and machine construction are carried on, and there are flour-mills, brick-works, saw-mills, sulphur refineries and leather and paper works.
The principal industries are refineries for preparing whale and seal oil and saw-mills.
On some plantations making sugar for particular markets and use in refineries it is the custom to make only one class of sugar, by boiling the molasses produced by the purging of one strike with the sugar in the next strike.
When Cuba was the chief sugar-producing country making clayed sugars it was the custom (followed in refineries and found advantageous in general practice) to discharge the strike of crystallized sugar from the vacuum pan into a receiver heated below by steam, and to stir the mass for a certain time, and then distribute it into the moulds in which it was afterwards clayed.
When centrifugals were adopted for purging the whole crop (they had long been used for curing the second or third sugars), the system then obtaining of running the sugar into wagons or coolers, which was necessary for the second and third sugars' cooked only to string point, was continued, but latterly " crystallization in movement, a development of the system which forty years ago or more existed in refineries and in Cuba, has come into general use, and with great advantage, especially where proprietors have been able to erect appropriate buildings and machinery for carrying out the system efficiently.
In a process employed with great success in some refineries the raw sugars are washed before being melted, and thus a purer article is obtained for subsequent treatment.
In some refineries the travelling cranes are now run by electricity, which still further facilitates the work.
A small pipe entering below the false bottom allows the air in the cistern to escape as it is displaced by the water or syrup. In some refineries this pipe, which is carried up to a higher level than the top of the cistern, is fitted with a whistle which sounds as long as the air escapes.
In most modern refineries the cisterns are so arranged that the spent char falls on to a travelling band and is conducted to an elevator which carries it up to the drying floor of the charcoal kiln.
In the best-appointed refineries the whole of the work in connexion with the char is performed mechanically, with the exception of packing the filter cisterns with fresh char and emptying the spent and washed char on to the carrying bands.
In former days, when refining sugar or " sugar baking " was supposed to be a mystery only understood by a few of the initiated, there was a place in the refinery called the " secret room," and this name is still used in some refineries, where, however, it applies not to any room, but to a small copper cistern, constructed with five or six or more divisions or small canals, into which all the charcoal cisterns discharge their liquors by pipes led up from them to the top of the cistern.
- Systematic feeding for the vacuum pan and systematic washing of the massecuite have been recently introduced not only into refineries, but also into sugar houses or factories on plantations of both cane and beetroot, and great advantages have resulted from their employment.
The most productive of the Piura wells are at Talara and Zorritos, where refineries have been established.
Petroleum refineries, iron-foundries, chemicals, soap-boiling, silk-spinning and the production of ships' fittings, as marine steam boilers, anchors, chains, cables, are the other principal branches of industry.
Natural gas and oil were found here in 1899, and Chanute became one of the leaders of the Kansas independent refineries in their contest with the Standard Oil Company.
Osaka possesses iron-works, sugar refineries, cotton spinning mills, ship-yards and a great variety of other manufactures.
In 1906 sugar refineries were projected at Hamilton, Kalispell, Chinook, Laurel, Missoula, Dillon and Great Falls; and in 1907 the crop was so large that 12,000 freight cars were needed to carry it and the railways had a car and coal " famine."
In 1920-1 some 715,000 tons of sugar were produced, 189 factories and refineries being engaged in the industry, and 300,000 tons were available for export.
Petroleum, or rather the heavy oils obtained in tar refineries, having an equal or superior heating power to coal-gas, may also be used in laboratories for producing high temperatures.

It contains iron foundries, shipbuilding yards, refineries, and other industrial establishments, and enjoys a considerable river trade in grain and coal.
Then follow the petroleum refineries and kindred industries, saw-mills and the fabrication of various wood articles, paper and milling.
The industrial development has been rather slow: sugar-refineries, tea-packing, oil-mills, tanneries, steam flour-mills, iron and mechanical works, factories of jute sacks, chemical works, tin-plate works, paper-factories are the chief.
The local industries are unimportant, consisting of saw-mills, rope-yards, salt refineries, and sail-cloth and margarine factories.
These include petroleum refineries, iron foundries, distilleries, flour mills, sugar refineries, sawmills, paper mills, chemical works, glass works, soap and candle works, &c. A law passed in 1887 provided that any one undertaking to found an industrial establishment with a capital of at least £2000, or employing at least 25 workmen (of whom two-thirds should be Rumanians), should be granted 12 acres of state land, exemption for a term of years from all direct taxes, freedom from customs dues for machinery and raw material imported, exemption from road taxes, reduction in cost of carriage of materials on the state railways, and preferential rights to the supply of manufactured articles to the state.
