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 relevant gas distribution network in 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.
- the invention is therefore based on the object to provide an apparatus and a method for odorizing a gas stream in a gas network, with which the aforementioned disadvantages are eliminated.
- the invention is in particular the object of providing a device for odorization of a gas stream in a gas network and a corresponding method, with which a more effective metering of the liquid odorant in the gas stream in dependence on the size of a funded by the gas line of the gas network gas flow is possible.
- An apparatus for odorizing a gas stream in a gas network comprises means for storing and metering a liquid odorant depending on the size of a gas flow through a gas line of the gas network, means for injecting the odorant in the gas line, at least one feed device, in the Gas line is arranged and at least one gas-permeable and wettable with odoriferous vaporizing body which extends within the gas line and which fills at least 50% of the free cross-section of the gas line, wherein the at least one feed device is arranged relative to the vaporizing body so that the emerging from the Impfdüse Odorant wetted the vaporizer body.
- the feed device is preferably designed as a vaccine.
- the device according to the invention differs in particular from the prior art that a gas-flowable and wettable with odoriferous vaporizing body is provided which extends over a substantial part of the free cross-section of the gas line and this cross-section fills so that it completely from that through the Gas-flow guided gas volume flow is positively flowed through, wherein the evaporation body has an increased surface wettable with the liquid odorant, so that ultimately ensures that the exiting from the injection nozzle odorant is not entrained in the form of drops with the gas stream, so that a quasi-continuous evaporation of the Odorizer can be achieved, although the odorant is applied in liquid form discontinuously on the evaporation body.
- an odorizing agent may be, for example, a sulfur-containing compound such as tetrahydrothiophene or ethylmercaptan or butyl mercaptan or also low-sulfur and sulfur-free organic compounds based on acrylate.
- a pulse-controlled metering pump for example as a piston pump, which is controlled by a pulse generator, wherein the pulse generator can receive a control pulse from a gas meter or a Mengenmengenumwerter, via a pulse converter is processed.

- the evaporation body extends over the entire clear width and preferably over the entire clear cross section of the gas line.
- an open-pored foam body may be provided as the evaporation body, preferably one which has a certain intrinsic stability, for example a hard foam body.
- Suitable and useful as an evaporation body in the context of the present invention are foam bodies having a flow-through macroporous structure.

- the pore diameter of the macroporous structure of the foam body according to the invention is preferably of the order of hundredths of the inner diameter of the gas pipe.
- the gas line may for example have an inner diameter of 1000 mm to 3000 mm, in this case, the pore diameter of the Schaumköpers be between 3 mm and 6 mm, so that no significant pressure losses are generated by the evaporation body within the gas line.
- the foam body is designed as a metal foam, for example as aluminum foam.

- the gas passing through the evaporation body then causes the odorant to evaporate, so that the evaporated odorant is carried along with the gas stream.
- the at least one feed device can open into the gas line at the circumference of the gas line, wherein in this case several feed devices can be distributed over a circular arc segment of the gas line.
- the at least one feed device is arranged in the direction of gravity above the evaporation body and is preferably connected directly to this, so that the exiting from the feed odorant directly wets the evaporation body.
- the feed device can also be arranged within the evaporation body.
- the evaporation body is arranged in a flow-through and preferably exchangeable cassette.
- Such a variant of the arrangement of the evaporation body can also be provided when the evaporation body is designed to be self-supporting stable in the form of a rigid foam.
- the evaporation body can also be formed as an open-pored soft foam body, which is held in a cassette. Then, for example, the cassette as a whole can be exchangeable, if necessary, the evaporation body can also be removed from the cassette in the sense of interchangeability.
- the at least one feed device is arranged at the leading end of a radially extending into the gas pipe dip tube and an orifice of the feed device approximately co-axial to the longitudinal center axis and preferably in the longitudinal central axis of the gas line is aligned.
