Definitions
- the invention firstly relates to a device for connecting a production facility for non-fossil natural gas to a gas distribution network, in particular a public gas distribution network, in which the supply of gas to the network is measured and monitored.
- JP 57 200799 A discloses a technical solution for switching from a city gas supply to natural gas supply using a satellite supply system.
- a natural gas substituting the city gas is prepared from city gas and propane gas derived from a tank.
- the city gas is adjusted to a predetermined pressure by a compressor and a pressure adjuster sets the pressure of the propane gas. Then the components are premixed by a pre-mixer and subsequently re-mixed in an after-mixer prior to supply to the city gas supply area.
- the public gas distribution network for natural gas consists of a nationwide high-pressure network with branch lines to regional and local distribution networks in which the pressure is lower (usually 8 bar or less).
- the network operator is responsible for the quality of the natural gas, both with regard to composition and with regard to heat content.
- the present invention relates to the introduction of non-fossil natural gas into such a network, generally the local network which is at relatively low pressure.
- stringent requirements have to be imposed on the non-fossil natural gas which is to be introduced into the network.
- the composition and therefore the properties of the non-fossil natural gases can vary considerably, depending on the process which is used to process the biological residual and waste material, the starting material and the process conditions which are applied.
- the device for connecting a production facility for non-fossil natural gas to a gas distribution network comprises a supply line for introducing non-fossil natural gas produced in said production facility, provided with at least one shut-off valve; a return line for returning non-fossil natural gas which is flow-connected to said supply line via a shut-off valve; a discharge line for discharging non-fossil natural gas which is flow-connected to said supply line via a shut-off valve; pressure-reducing means for reducing the pressure of non-fossil natural gas produced in said production facility to a predetermined value; a flow meter for measuring the flow rate of non-fossil natural gas; a measuring device for measuring the caloric value of non-fossil natural gas or a characteristic related thereto at a location upstream of the shut-off valve in the supply line; an analyzing device for at least partially analyzing the composition of non-foss
- the device according to the invention is an independent apparatus which can readily be placed between any production facility for non-fossil natural gas with its own process-specific process control unit and the public gas distribution network, and which can measure and monitor the quality and quantity of the non-fossil natural gas which is to be supplied to the gas distribution network depending on the production facility used, the specific process used, the process conditions and starting materials.
- the device according to the invention comprises a supply line between the production facility and a shut-off valve.
- this supply line the gas produced in the production facility flows.
- the quality of the gas is measured in this line by means of gas-sampling devices using component analysis in the analyzing device and a determination of the caloric value or characteristic related thereto in said measuring device.
- the caloric value usually has to be within a defined range having an upper limit and a lower limit.
- the complete composition of the non-fossil natural gas will be determined, although in most cases a more limited analysis of the hydrocarbons which are present (mainly methane) and carbon dioxide would suffice.
- the shut-off valve is operated on the basis of the measured values. If the gas is of the desired quality, it will flow to the distribution network via the pressure-reducing means and via the shut-off valve in the discharge line.
- the pressure-reducing means lower the pressure of the non-fossil natural gas produced to a desired value, typically to the pressure prevailing in the public network in question. If the gas does not meet the quality standards, it will flow into the return line.
- This return line may, for example, be connected to the production facility, so that the gas is returned to the process or part thererof, for example, only to any possible working-up steps.
- the return line may also end in a flare, where the gas which has been produced is burnt.
- the flow meter measures the volume of gas per unit time, which gas is introduced into the distribution network.
- the control unit controls the shut-off valve, for example a three-way valve, on the basis of measured signals originating from the gas analyzer and the measuring device which are compared to predetermined values or ranges.
- the measuring device is preferably a (certified) meter for determining the Wobbe index of the gas to be supplied to the distribution network.
- the Wobbe index is an indicator for the combustion energy of the gas. In the Netherlands, natural gas in the standard network has a Wobbe index of between 43.46 and 44.41, for example.
- the gas-analysis device is preferably designed to analyze at least the CO 2 , O 2 and H 2 S content of the biogas. These are gases which are frequently found in biogas. These gases should only be present in the distribution network in limited amounts. In addition, the temperature, hydrocarbons (in particular methane) and relative humidity are advantageously determined as well.
- Sampling, analysis and measurement are preferably carried out semi-continuously, it being possible for the periodicity of the analysis and of the measurement to differ with respect to one another.
- the supply line, return line and discharge line are provided with gas-sampling devices which allow gas samples to be taken from these lines.
- the control device preferably comprises a memory for storing data originating from the analysis device, measuring device and flow meter, which can be used later for verification and/or billing purposes.
- the memory can advantageously be accessed remotely, for example via a telephone line or in another telemetric way.
- the invention also relates to an assembly comprising a production facility for producing non-fossil natural gas and the coupling device according to the invention.
- a production facility for producing non-fossil natural gas from biological residual material, such as manure or sludge is denoted by reference numeral 10.
- the regional distribution network which distributes natural gas to private and industrial users is denoted by reference numeral 12.
- a coupling device 14 according to the invention is situated between the production facility 10 and the network 12.
- the independent device 14 generally comprises a housing 16 inside which the various components are arranged.
- the device 14 comprises a supply line 18 which is coupled to the production device 10.
- a gas analyzer 20 for at least CO 2 , O 2 and H 2 S and a Wobbe index meter 22 are coupled to this supply line 18 upstream of a shut-off valve 24.
- Signals originating from the gas analyzer 20 and the meter 22 are processed by the control device 26 in order to control shut-off valve 24.
- the shut-off valve 24 connects the supply line 18 to either a discharge line 28 which is connected to the network 12 or to return line 30 which in this case is connected to the production device 10.
- Pressure-reducing means 38 for example a reduction valve, and a flow meter 32 are provided in the discharge line 28, the signals of which are transmitted to control device 26.
- This control device 26 comprises a memory 34 for storing data. As has been indicated above, these data can be passed on for billing purposes, for example by means of a communication means (not shown), such as a telephone, a computer, etc.
- Reference numeral 36 denotes the relevant sensors of the gas analyzer 20, Wobbe index meter 22 and flow meter 32.
