treatment of gases
Gas is treated before it can be supplied to the marketplace. The extent to which gas needs to be processed will depend on its quality, the amount of associated impurities such as water, carbon dioxide and sulphur compounds, and the ultimate end-use for the gas. Common gaseous impurities found in natural gas are carbon dioxide and sulphur compounds. Both have an acidic reaction and are given the generic name 'acid gases'. These gases can be removed by a number of commercial processes, using either a physical or a chemical solvent. Physical solvent processes tend to be used where gas pressures are high and for gases with lower levels of propane and heavier hydrocarbons. (Source: SHELL)

acid deposition
A type of pollution which washes out of the atmosphere as dilute sulphuric and nitric acids. It tends to be a regional rather than a global phenomenon, linked to particular industrial activities and meteorological conditions. It includes rain, more than normally acidic snow, mist, sleet, fog, gas and dry particles. It upsets the balance of nature, disrupting ecosystems, and destroys forests and woodlands, plants and crops; kills aquatic life by altering the chemical balance of lakes and rivers and corrodes building materials and fabrics. The pollutants are caused principally by discharges from power station chimneys of sulphur dioxide and nitrogen oxides released by burning fossil fuels, coal and oil. (Source: WRIGHT)

sulphur
A nonmetallic element existing in a crystalline or amorphous form and in four stable isotopes; used as a chemical intermediate and fungicide, and in rubber vulcanization. It is deposited from volcanic vents and fumaroles and also is found in sedimentary rocks, particularly with gypsum and limestone, and associated with salt-domes. Native sulphur is the main source of sulphur for the sulphuric acid industry, followed by sour gas (natural gas containing hydrogen sulphide) and pyrite. Sulphur is an essential plant macronutrient.

sulphur dioxide
Emissions of the gas given off during the burning of fossil fuels in power stations and other boilers. Sulphur dioxide is created because sulphur is an impurity in most coal and oils. When the fuel is burned the hot sulphur reacts with oxygen in the atmosphere to form sulphur dioxide. (Source: WRIGHT)

5 выключатель элегазовый
выключатель элегазовый
Выключатель газовый, контакты которого размыкаются и замыкаются в элегазе (шестифтористой сере).

sulphur hexafluoride circuit-breaker
SF6 circuit-breaker
a circuit-breaker in which the contacts open and close in sulphur hexafluoride

disjoncteur à SF6
disjoncteur dont les contacts s'ouvrent et se ferment dans l'hexafluorure de soufre
[IEV number 441-14-31]Для РУ напряжением 110 кВ и выше (вплоть до 1150 кВ) наиболее широко используются воздушные выключатели, где гашение дуги осуществляется потоком сжатого воздуха. Однако в последнее время они вытесняются элегазовыми выключателями, в которых в качестве дугогасящей среды используется электроотрицательный газ — шестифтористая сера (элегаз). Такие выключатели создаются для герметичных распределительных устройств (ГРУ), а также для наружной установки. Использование элегаза в качестве дугогасящей среды обусловлено его высокими изоляционными и дугогасящими свойствами. Это позволяет создать более совершенные выключатели с меньшим числом дугогасительных разрывов, с меньшими габаритами и более надежные в эксплуатации.
