Definitions

  • the invention relates to a method and a device for providing a continuous supply of natural gas in a pipeline network.
  • liquid natural gas The liquid form of natural gas, hereinafter referred to as liquid natural gas, has a relatively high energy density: natural gas only has an energy density of approx. 9 kWh / Nm 3 , while liquid natural gas has an energy density of approx. 6 kWh / l. Liquid natural gas is therefore well suited for storing energy. For this reason, natural gas is transported in ships in liquid form from the producing countries to the consumer countries, and liquid natural gas is used as a fuel for motor vehicles.
  • Liquid natural gas is also considered by energy companies Winter storage used. Because that is often used for heating purposes Natural gas has a seasonally fluctuating demand. For the cover very high demand for natural gas, especially in the winter months, in addition to a winter stock in natural Underground storage also created storage tanks with liquid natural gas. The Liquid natural gas is often only used to cover peak loads used. These storage tanks for liquid natural gas are used in the summer filled and remain refrigerated until it reaches such high levels on a few winter days Withdrawals of natural gas from the pipeline of the natural gas network of the Power company comes that gas pressure in the pipeline collapsing. Then the liquid natural gas is evaporated and into the Grid fed.
  • the natural gas is liquefied through the use of mechanical refrigeration circuits.
  • gases partly the natural gas itself, are compressed, cooled and relaxed again.
  • the relaxation cold released in the process becomes cooling second hand.
  • High pressures up to over 200 bar and low temperatures from below -160 ° C place high demands on the systems used. This Plants are relatively maintenance-intensive and their operation is therefore relatively expensive.
  • the invention has for its object the disadvantages of the state mentioned to overcome technology and to create a method and a device where a continuous natural gas supply in a pipeline network ensured and at the same time on a use of filled in summer, very large storage containers for liquid natural gas at least partially waived can be.
  • the object underlying the invention is achieved by a method for Provision of a continuous natural gas supply in a pipeline network solved, in which natural gas in the daytime without very high natural gas withdrawal from the Pipeline network is removed and using a low-boiling liquid Gases, especially nitrogen, oxygen or argon, or in individual cases also hydrogen, helium or another low-boiling gas is liquefied, in which the liquefied natural gas is supplied to a storage container in which in times of day of a very high natural gas withdrawal from the pipeline network liquefied natural gas removed from the storage container, evaporated and the Pipeline network is fed again.
  • a low-boiling liquid Gases especially nitrogen, oxygen or argon, or in individual cases also hydrogen, helium or another low-boiling gas is liquefied
  • a “very high natural gas extraction” here means in particular one Natural gas extraction greater than approx. 20% than the arithmetic mean of Natural gas extraction based on the whole day.
  • times of day without very high Natural gas extraction is the night hours, especially from 10 p.m. to 5 a.m. meant and under “times of day with a very high natural gas withdrawal” are here understand the hours of the day, especially from 5 a.m. to 10 p.m.
  • the object underlying the invention is further achieved by a method for Provision of a continuous natural gas supply in a pipeline network solved, in the natural gas from the pipeline network in a suitable amount is removed if the weather conditions require a very high amount of natural gas or can be expected for several days from the pipeline network without Feeding this additional natural gas from the storage container does not increase would cover where the extracted natural gas with the help of a low-boiling liquid gas, in particular nitrogen, oxygen or argon, is liquefied, in which the liquefied natural gas is fed to a storage container and on Days and / or times of the day a very high natural gas withdrawal from the Pipeline network removed the liquefied natural gas from the storage container, evaporated and fed back into the pipeline network.
  • a low-boiling liquid gas in particular nitrogen, oxygen or argon
  • the natural gas withdrawn from the pipeline is preferably liquefied according to the invention with a liquefaction device which has a liquefaction capacity greater than the maximum withdrawal requirement times the withdrawal time by the minimum liquefaction time, which typically means in the order of magnitude greater than 5000 m 3 / h.
  • the invention opens up through the use of a low-boiling liquid Gases, especially nitrogen, oxygen or argon essential Potential savings and also reduces maintenance costs. Because the technically complex and maintenance-intensive mechanical refrigeration circuits for liquefaction are not necessary here. Doing so will be a continuous Natural gas supply in the pipeline network due to the relatively high Liquefaction performance of the liquefaction device ensured. Because about Relatively short periods of time can empty storage tanks again with liquid natural gas be filled.
  • natural gas is withdrawn from the pipeline network when the Pressure in the pipeline network is more than 1 bar higher than the pressure at the feed is present.
  • the liquefied natural gas from the The storage container is removed and returned to the pipeline network, when the pressure in the pipeline network has dropped more than 1 bar compared to the pressure that is present during the liquefaction time.
  • the feed pressure of the natural gas into the pipeline network is higher or equal to the condensing pressure and a pressure increase on Storage tanks are made by a pressure build-up evaporator or by means of a Pump, but preferably pressure build-up evaporator, in the relatively short time between liquefaction and feed.
  • natural gas is produced using cryogenic liquid nitrogen liquefied. This has the advantage of being simple and therefore relative cost-effective and trouble-free plants at short notice large amounts of natural gas can be liquefied.
  • the natural gas is on days and / or Times of day taken from the pipeline network and liquefied, in which Withdrawal capacity is free.
  • the liquefied natural gas is on days and / or times of day removed from the storage container and fed back into the pipeline network, in which the pipeline cannot deliver the required quantity.
  • the liquefied natural gas is only used for a period of approx. 24 hours in the reservoir before it reaches the pipeline network is fed.
  • This measure advantageously leads to a) a very high stock is low, b) there are no losses due to evaporation, and c) the storage container replenishes is empty again and therefore poses no danger.
  • liquefied natural gas is additionally in at least the same or a second reservoir, with the additional natural gas was liquefied earlier but has not yet been released. This can advantageously extend the buffer period.
  • the object underlying the invention is further achieved by a device to provide a continuous natural gas supply in one Pipeline network solved that a sampling line for a natural gas extraction the pipeline network, an adjoining device for liquefaction of the extracted natural gas with a feed line for a low-boiling liquid gas, especially nitrogen, oxygen or argon, and one to the Device for liquefying subsequent storage container for liquefied Has natural gas, which storage container with a feed line for liquid Natural gas in an evaporator and heating device and in the pipeline network is connected, the device for liquefying a heat exchanger which has a cryogenic, adsorptive or permative gas cleaning is connected upstream.
  • the heat exchanger is operated with cryogenic, liquid gas, preferably nitrogen operated. It is advantageously achieved that a) none mechanical and therefore fault-prone machines are necessary, b) the Nitrogen can be stored relatively easily on site for 1 to 2 liquefaction days can and c) the very high condenser performance required very inexpensively can be created.
  • the natural gas is liquefied in summer - the time of overcapacity - and used in winter during fewer peak load hours.
  • the system is designed to cover an additional requirement for 4 hours on 20 days of winter. This can occur, for example, in the morning when the apartment heaters start up.
  • the entire quantity must be stored in relatively large storage containers (tanks) from the moment of liquefaction until the time of use. This storage is associated with considerable energy losses.
  • the condenser capacity is usually doubled due to maintenance-related failures.
  • the invention is based on the fact that even on extreme winter days, where peak load coverage is sometimes required, to others Times of day (e.g. at night) still free transport capacity in the pipeline is available. This is removed at night and depending on the weather for the liquefied the next day or, depending on the weather forecast, a few days before the Cold period liquefied for a longer period.
  • a daily amount is liquefied according to the invention at the beginning of the cold days. Depending on the weather forecast, this can be done one or more days before an expected cold front. After this quantity has been reduced in the peak demand hours, the process repeats itself depending on the temperature development.
  • Such a large condensing capacity can only be achieved with a very powerful condenser that can be started up very quickly and reliably.
  • Such a condenser is preferably a heat exchanger with upstream adsorptive or permeative gas cleaning.
  • the heat exchanger preferably evaporates and heats cryogenic liquid nitrogen and cools and liquefies the natural gas.
  • the specific need for cryogenic liquid nitrogen is around 2 kg per kg of liquefied natural gas, depending on the pressure.
  • the required amount of stock and the storage time are significantly shorter compared to the conventional system according to the prior art.
  • the costs for a 2000 m 3 / h heat exchanger are also lower than for a 20 000 m 3 / h condenser with mechanical operation.
  • the conventional liquefaction for 2000 m 3 / h is technically much more complex and therefore more expensive than a liquefaction according to the invention for 20,000 m 3 / h with liquid nitrogen. Because a flat-bottom tank for 4 million m 3 is more complex than one or more vacuum-insulated tanks with a total capacity of 140 t.
  • the energy consumption of the conventional system according to the prior art is also very high due to the high storage losses of the 1/2-year storage period and the poor efficiency of cooling circuits at temperatures around -160 ° C.
  • the condensation consumes approximately 200 Wh / kg of liquid nitrogen. Taking into account the efficiency of conventional cooling, this corresponds to 1 to 1.5 kWh / kg of electrical motor power.
  • Another advantage lies in the fact that in mild heating periods there is no need for liquefaction, which means no costs attack.
  • the plant according to the invention then stores no natural gas and thus provides also not a security risk. In severe winters, however, the system according to the invention can be used almost daily. The cost is then Although higher, the security of supply remains guaranteed.
  • the natural gas withdrawn from the natural gas line 1 is via lines 2 and 3 or 4 each part 5a or 5b of a gas cleaning system, e.g. Konadsorbtionsstrom, supplied, the parts 5a or 5b mutually operate.
  • the purified natural gas is supplied via lines 6 or 7 and 8 one or possibly two-stage heat exchanger / condenser 9 supplied, in which it is condensed.
  • the heat exchanger / condenser 9 is Liquid nitrogen is supplied via a line 10 from a tank 11 and through a line 12 led away again in gaseous form. This may be in two stages executed heat exchanger / condenser 9 liquefied natural gas is via a Line 13 fed to a tank for liquid natural gas 14. No one is required for this Pressure increase.
  • the tank 14 is designed depending on the application for a one-day or multi-day requirement.
  • the filling of the tank 14 will according to a consumption forecast, for example depending on Weather data, such as temperature and wind data, regulated. If necessary, that means that if the pressure in line 1 is too low, the liquid natural gas will run out the tank 14 via a line 15 to an evaporator 16.
  • the Evaporation takes place through external heating or air evaporators.
  • the natural gas is then fed via a line 17 to a feed device 18, and optionally conditioned, that means for example a Gas odorization or readjustment of the gas quality to the in line 1 provide the required natural gas composition before it has a Line 19 is fed back to the natural gas line 1.
  • Via a line 20 can Return gas from the gas cleaning system 5a, 5b into the natural gas line 1 to be led back. If for the withdrawal of this cleaning residue no gas line of low pressure is available, must be replaced by a Pressure increase unit of the pressure loss in the gas cleaning system 5a, 5b be compensated.
  • the feed into the natural gas line 1 requires here advantageously no compressor or pump. Liquefaction can take place at the Line pressure of natural gas line 1 take place.
  • the tank 14 is provided with a line 21 from the liquid side Phase of the tank 14 into a heat exchanger 22 and from the heat exchanger 22, wherein natural gas is evaporated via a line 23 to the gas phase side Tanks 14 connected. This leads to a pressure build-up in the tank 14. Line 21 is closed before the subsequent liquefaction.
