3) хранение природного газа. В странах с большими сезонными колебаниями температуры потребность населения в природном газе в холодные зимы неизбежно возрастает. Для удовлетворения этого дополнительного сnроса важно хранить запасы газа. Для этого используют два способа
Преобразование в СПГ и хранение в охлаждаемых резервуарах. этот сnособ приемлем, если речь идет об относительно небольших объемах. Подземное хранение либо в поровых коллекторах, либо в пещерах Наиболее широко распространенным способом хранения больших объемов природного газа является хранение в пустых пещерах или в пористых породах например в истощенных коллекторах газа или нефти и водоносных пластах которые используются как гигантские подземные резервуары для хранения газа, пока он не понадобится на рынке. Однако многие из них слишком велики для того, чтобы служить эффективными хранилищами, Поскольку для создания необходимого внутреннего давления потребовался бы слишком большой объем газа. В идеале, истощенное месторождение должно быть относительно небольшим, должно располагаться недалеко от рынка и должно быть достаточно герметичным (с точки зрения геологических условий), чтобы не допускать утечки газа в окружающие горные породы.

4) Еще одним удобным местом для хранения являются соляные пещеры. Соляной раствор откачивается и заменяется газом. Глубина и размеры пещер могут быть различными, но, как правило, их высота составляет от 100 до 400 метров, при диаметре 100 метров и глубине залегания от 500 до 2000 метров. Газ, который хранится в соляных пещерах, как правило, впитывает дополнительную влагу, поэтому все соляные пещеры оснащаются дегидрационными установками. В настоящее время для хранения газа во всем мире используются 33 соляные пещеры, свыше половины из них находятся в США. В ряде стран используются пещеры в горной породе, которые часто необходимо выстилать изнутри стальными или пластмассовыми листами для предотвращения утечек. в пещерах с такой внутренней облицовкой газ хранится более или менее идеально, поэтому никакой последующей подготовки газа не требуется. При использовании пещер в горной породе без облицовки, хотя они обходятся дешевле, необходимы специальные очистные сооружения для удаления любых примесей, которые могли попасть в газ, прежде чем его можно будет направлять потребителям.

3) natural gas storage. In countries with large seasonal temperature fluctuations in natural gas demand of the population in cold winters inevitably increases. To meet this additional snrosa it is important to store gas reserves. To do this, use two waysConversion to LNG and storage in refrigerated tanks. This snosob is acceptable, if you're talking about a relatively small volumes. Underground storage either in pore reservoirs or in caves, the most common way to store large amounts of natural gas in storage is empty caves or in porous rocks such as depleted oil or gas reservoirs and aquifers which are used as a giant underground tanks for gas storage until needed for reankeh. But many of them are too large to be effective, since the required internal pressure would require too much gas. Ideally, the exhausted mine should be relatively small, must be close to the market and should be sufficiently tight (in terms of geological conditions) to prevent gas leakage into the surrounding rocks. 4) another convenient place for storage are salt caves. Saline solution is pumped out and replaced with gas. The depth and size of the caves may vary, but generally, their height ranges from 100 to 400 meters, with a diameter of 100 meters and a depth of 500 to 2000 meters. Gas, which is stored in salt caverns, tend to absorb more moisture, so all salt caves are equipped with degidracionnymi units. Currently for gas storage worldwide used 33 salt caves, over half of them are in the United States. In a number of countries used the caves in the rock, which is often necessary to build from inside steel or plastic sheets to prevent leaks. in the caves with such internal lining of gas is kept more or less perfectly, so any subsequent preparation of gas is not required. When you use the caves in the rock without facing, although they are cheaper, requires special treatment facilities to remove any impurities that might get caught in the gas before it can be sent to consumers.

3) storage of natural gas. In countries with large seasonal temperature fluctuations in population demand for natural gas in the cold of winter inevitably increases. To meet this additional snrosa important to keep gas reserves. For this purpose, two methods of
conversion to LNG and storage in the cooling tank. snosob this is acceptable, if it is a relatively small scale. Underground storage or porous reservoirs, or in caves The most common way to store large volumes of natural gas is stored in empty caverns or porous rocks such as in depleted reservoirs of gas or oil, and aquifers that are used as giant underground storage tanks for gas, while he It does not need on the market. However, many of them are too large to serve as effective storage, because to create the necessary internal pressure would have required too much gas. Ideally, the depleted field should be relatively small, should be located close to the market and must be sufficiently tight (in terms of geological conditions) to prevent gas leakage in the surrounding rocks.

4) Another good place to store are the salt cave. The brine is pumped out and replaced by gas. The depth and dimensions of caves may be different, but as a rule, their height is 100 to 400 meters, 100 meters in diameter and depth of from 500 to 2000 meters. The gas, which is stored in salt caverns, usually absorbs more moisture, so all the salt caves are equipped with dehydration plant. Currently, the storage of gas in the world used 33 salt caves, more than half of them are in the United States. In some countries, use of the cave in the rock, which is often necessary to pave the inside with steel or plastic sheets to prevent leaks. caves with a lined gas is kept more or less perfect, so no subsequent gas treatment is required. When using caves in the rock without covering, although they are less expensive, require special treatment facilities to remove any impurities that may have gotten into a gas before it could be sent to consumers.

(3) the storage of natural gas. in countries with large seasonal fluctuations in temperature demand for natural gas in the cold winter will inevitably increase. to meet this additional сnроса is important to keep the gas reserves. the use of two waysthe conversion to cng and stored in refrigerated containers. this сnособ is acceptable, if it is a relatively small volume. underground storage in either поровых reservoirs or in caves. the most common way to store large volumes of natural gas is stored in the empty caves or in porous rocks such as depleted reservoirs of gas or oil and water beds which are used as a giant underground tanks for the storage of gas, until needed in the market. however, many of them are too large to be efficient storage, since the creation of the necessary internal pressure would require too large a volume of gas. ideally, aching deposit should be relatively small, must be located not far from the market and should be leak proof (in terms of the geological conditions, to prevent the leakage of gas in the surrounding rock samples.4) a convenient place for the storage of the salt caverns. saline drained and replaced with gas. the depth and size of the caves may be different, but generally their height ranges from 100 to 400 meters, 100 meters in diameter and depth data from 500 to 2000 meters. the gas, which is stored in salt caverns typically absorbs more moisture, so all the salt caverns are дегидрационными installations. currently for gas storage in salt caverns used 33 worldwide, over half of them are in the us. in a number of countries used the caves in the mountain rocks, which often need to be выстилать inside steel or plastic sheets to prevent leaks. in the caves with an internal lining, gas is more or less perfect, however no further training of gas is not required. with the use of the caves in the mountain rocks without lining, although they are cheaper, require special treatment facilities to remove any impurities, which can go into a gas before it can be sent to consumers.
