Definitions

  • the invention relates to a device comprising means for storing and metering a liquid odorant as a function of the size of a conveyed through a gas line of the gas network gas flow, means for injecting the odorant in the gas line and at least one Impfdüse.
  • the invention further relates to a method for the odorization of a gas stream comprising the metering and injection of a liquid odorant into a gas stream as a function of the size of the gas volume flow conveyed through the gas line.
  • the treated natural gas does not have a sufficient warning smell, it must be odorized according to legal regulations. For this reason, it is known and customary to add odorant to the natural gas.
  • odorants are usually malodorous substances into consideration, which give the natural gas a sulfur-like odor.
  • a widely used odorant is, for example, tetrahydrotiophene (THT).
  • THT tetrahydrotiophene
  • low-sulfur and sulfur-free odorants have also been used for several years.
  • natural gas is provided odorierffenza in the gas transport networks (long distance transport lines), an odorization then takes place by the gas network operator of the gas distribution network in question during the removal of the gas from the gas transport network and its pressure reduction to the pressure prevailing in the gas distribution network pressure.
  • a liquid odorant is added via an odorizer in a local gas pressure regulating and measuring system (GDRM system).
  • GDRM system local gas pressure regulating and measuring system
  • the addition takes place in dependence of the size of a standardized gas volume flow calculated from the data of the Gas meter and the gas temperature and the gas pressure.
  • a corresponding amount of odorant is fed by means of a pulse-controlled metering pump a Impfdüse, which is designed as inserted into the gas pipe dip tube.
  • the odorant is supplied to the gas stream, for example, in Germany with a value of at least 10 mg / m 3 of gas volume. It is important to ensure that a predetermined limit, for example, 10 mg / m 3 , is not exceeded during the entire transport of the gas.
  • the odorant is intermittently supplied to the dip tube inserted into the gas line, wherein the dip tube is flowed around by the gas flowing through the gas line. The liquid odorant evaporates and is absorbed by the natural gas.
  • the odorant Since the odorant is not atomized during injection into the dip tube and the odorant is fed intermittently in the gravitational direction of the dip tube, it is not excluded that the odorant does not evaporate on or in the dip tube and that significant amounts of liquid odorant through the gas stream be entrained and distributed uncontrollably in the gas line. So it has already occurred in practice that accumulate significant amounts of liquid odorant below the Impfdüse in the gas line.
