Definitions

  • the present invention concerns transport, storage and distribution of compressed natural gas (CNG).
  • CNG compressed natural gas
  • the invention concerns a system for transport and storing of compressed natural gas (CNG) at high pressure (HP) and distribution of the stored compressed natural gas at high pressure (HP), medium pressure (MP) and low pressure (LP) at large industrial scale.
  • CNG compressed natural gas
  • HP high pressure
  • MP medium pressure
  • LP low pressure
  • a pressure container for transportation of natural gas from a gas source at high pressure is associated with a low initial temperature because the gas must be choked before reaching the empty container, which involves a substantial pressure difference.
  • the initial temperature may fall to e.g. -100 °C which will result in the formation of gas hydrates and ice unless the gas has been dried in a molecular sieve gas drier.
  • the very low temperature may cause great material related problems for the construction. Further, very high gas speeds and choked flow in the tube system will occur, and the time for filling the tank can be very long.
  • the transport container may be loaded directly without significant temperature problems.
  • One example is high temperature gas downstream export compressors. Unloading from a pressure container is also associated with low temperatures. The receiving container will be subjected to expansion effects with associated low temperature during unloading of the transport container. A still more serious problem is the extremely low temperature which is obtained in the transport container per se due to expansion of gas in the container at near adiabatic conditions. The thermodynamic effect which occurs when gas in a container expands is different from the mechanism upon choking, and calculations show that the temperature of the gas and in the container upon unloading may sink to -150 °C.
  • Patent Publication US 4446804 a process for transportation of oil and gas at high pressure in tanks on board a ship is disclosed, whereby loading and unloading are carried out using a suitable liquid under pressure, for instance water, in the separate tanks.
  • the loading comprises filling a tank or group of tanks containing liquid under pressure with oil and gas while the pressurized liquid is simultaneously displaced to the next tank or group of tanks to be filled, whereupon the next tank/group of tanks is filled with the load while liquid under pressure is further displaced to a third tank/group of tanks and so on.
  • the unloading comprises removing the load from one tank or group of tanks by introducing a liquid under pressure into the tank/group of tanks, unload the load in the next tank/group of tanks through the transfer of liquid under pressure from the first tank/group of tanks to the next one and so on, whereby the ratio between oil and gas in the mixture is kept as constant as possible during the entire unloading operation by adjusting the unloading of gas from the different tanks or groups of tanks.
  • a system for transport and storage of compressed natural gas (CNG) at high pressure (HP) and distribution of said natural gas at high pressure (HP), medium pressure (MP) and low pressure (LP), which system comprises: i) transport units having one or several tanks for loading and transport of HP CNG and equipment for loading, internal transportation in the transport unit and unloading HP CNG and liquid at high pressure, ii) a storage unit having one or several tanks for storing of HP CNG and equipment for loading, internal transportation in the storage unit and unloading HP CNG and liquid at high pressure, and a storage tank for liquid which may be delivered at HP, MP and LP, and iii) a distribution unit comprising one or more tanks for HP CNG, one or more tanks for MP CNG and one or more tanks for LP CNG, which tanks are connected for distribution to consumers of HP CNG, MP CNG and LP CNG respectively, and equipment for loading HP CNG and internal transportation in the distribution unit of HP CNG, MP CNG and LP CNG and liquid, and equipment for
  • the system according to the present invention is distinguished in that its lay out is such that during fluid communication to or between units of the system or internally between tanks of the separate units a closed loop may be formed wherein gas at specific pressure is transported from one or more first tanks to one or more second tanks while liquid at the same pressure as the gas or marginally higher pressure is transported from said one or more other tanks to said one or more first tanks, the volume in said one or more first tanks being approximately equal to the volume of said one or more other tanks.

  • Both units may comprise several pressure containers produced from commercially available steel tubes which may be coupled together in groups.
  • the separate tanks of the transport unit or groups of tanks shall most preferably have the same volume as the separate tanks or groups of tanks of the storage unit. During the change of gas it is only need for a smaller amount of liquid corresponding to the volume of the segment or tank.

  • the distribution unit may comprise many tanks for CNG in each pressure range, preferably tanks of corresponding type as in the storage unit, so that loading from the storage unit may take place simply and uniformly.
  • the tanks may be in the form of tube sections mounted at a small angle (2° - 4°) to the horizontal in order to drain the liquid which is used during the loading sequence. This enables delivery of natural gas at high pressure at any time. If the loading pressure is 200 barg, one single tank may deliver gas at close pressure for only a short period of time. If the storage unit comprises many HP tanks, one single tank may deliver HP gas until the tank pressure falls towards the limit for the receiving unit. Then a new tank may take over, and the first tank may be used for delivery of MP natural gas and then for delivery of LP natural gas. Accordingly, the distribution unit may be optimized for the necessary delivery, independent upon whether this is at HP, MP or LP.
  • the further storage tank for liquid may be connected in order to deliver or receive liquid as demanded in order to avoid or cushion the previously mentioned temperature effects.
  • the previously mentioned significant temperature effects are prevented.
  • the sectioned transport, storage and distribution according to the invention for compressed natural gas at a pressure which may be higher than 220 barg and at surrounding temperature confers many advantages of which the most important ones are:
  • a compact storage unit compared with a traditional underground installation.
  • Gas network for delivery of gas at HP, MP and LP can be connected.
