Definitions
- the invention relates to a device for preheating a gas before its expansion in a gas pressure control and measuring system with the features of the preamble of claim 1 and a method for operating such a device with the features of the preamble of claim 13.
- Natural gas for the public gas supply is conducted under high pressure between approx. 40 and 80 bar over long distances to regional or municipal distribution networks. Under high pressure, gas is also temporarily stored in storage facilities in regional or municipal distribution networks. Before it reaches the end user, the gas in the gas pressure control and measuring system must be reduced to the lower supply pressure of approx. 20 - 50 bar in the regional or municipal distribution networks, to 3 - 12 bar in the main distribution rails and to 20 - 1000 mbar to the end user be relaxed. This relaxation leads to the Joule-Thomson effect, namely to the cooling of the gas.
- temperatures occur in the gas pressure regulating and measuring systems, at which it can be expected that either the gas hydrates contained in the gas will freeze inside the components of the gas pressure regulating and measuring system or that system parts, apparatus or devices will freeze due to condensates on the outside, malfunctions or failures of system parts or the entire gas pressure control and measuring system are to be expected.
- To impermissible hypothermia To avoid the gas at high pressure differences, it is known to warm the gas before the expansion. Inadmissible temperatures can occur particularly when there are faults in the heat supply to the heat exchangers.
- WO 94/11626 discloses a method and a device for expanding gas under high pressure in a line, in which a turbogenerator is used as the pressure reducing device, which is preceded by a heat exchanger.
- the heat exchanger is supplied with heat by at least one combined heat and power unit (CHP), which contains a gas combustion engine and a generator.
- the CHP is operated with the gas after the turbogenerator.
- the heat exchanger preheats the gas before it is fed to the turbogenerator for expansion. Both the CHP and the turbogenerator ' generate electrical energy that is fed into a power grid.
- CHP combined heat and power unit
- the gas preheater is supplied with thermal energy using conventional heating systems, i. H. with fuel gas fired boilers, as they are also used - depending on the performance requirement - in industrial, commercial or private areas.
- WO 94/11626 gives no information for the supply of gas pressure regulating and measuring systems with electrical energy.
- the object of the present invention is to propose a device and a method for preheating a gas before its expansion in a gas pressure control and measuring system, with which the energy supply to the system is improved, and a method for operating such a device.
- the solution is achieved with a device for preheating a gas before its expansion in a gas pressure control and measuring system with the features of claim 1 and a method for operating such a device with the features of claim 13.
- a device for heating a gas which is under high pressure in a line to a gas pressure control and measuring system is provided with a heat exchanger, a subsequent pressure reducing device to a further line and a heating device for the heat exchanger operated by the gas from the line.
- the heating device is designed as a gas-powered fuel cell, which additionally provided to the thermal energy electrical energy is adapted particularly advantageous to the needs of 'gas pressure regulating and •' measuring equipment and makes it particularly independently of other electric supply means.
- the device according to the invention advantageously saves primary energy compared to conventional heating systems without electricity generation. This leads to a reduction in the emission of C0 2 .
- the pipe-bound heat transfer pipe network consists of pipes, fittings, fittings and other components that are also used in conventional heating technology.
- Other thermal components include regulation and control devices and self-protection safeguards. Any excess thermal energy can be used elsewhere and fed into a district heating system, for example.
- the fuel cell is designed so / that it so that at least the requirement of the gas pressure regulating and measuring plant is fully covered in thermal energy at least completely supplies the heat exchanger with heat.
- the heat-side device downstream of the fuel cell supplies the heat circuit of the gas preheater exactly with the heat that is necessary to compensate for the reduction in the relaxation temperature, via a primary heat exchanger, which can also be designed as a heat pipe heat exchanger.
- a primary heat exchanger which can also be designed as a heat pipe heat exchanger.
- the fuel cell is designed so that the electrical energy generated by it for self-supply, for Operation of the gas pressure control and measuring system can be used and fed into a public electricity network, in particular.
- Different amounts of questions from the fuel cell available electrical energy based on the fact that the fuel cell in heat-controlled operation .lauft '.
- the thermal energy provided by the fuel cell varies with the gas throughput through the gas pressure control and measuring system.
- the electrical energy provided by the fuel cell correlates with the thermal energy emitted by the fuel cell.
- the electricity requirements of the fuel cell and the gas pressure control and measuring system are mostly almost constant. Electrical energy obtained from the fuel cell is initially used according to the invention in order to satisfy the fuel cell's need for electrical energy.
- the fuel cell which generates a large or larger amount of electrical energy compared to thermal energy, can cover the electricity requirement of a gas pressure regulating and measuring system in addition to the heat requirement and offer excess electrical energy to the market.
- the electrical components provided for this purpose are, for example, direct current circuits, fuses and switches, inverters with fuses, alternating current circuits with transformer and mains connection.
- the current-side device after the fuel cell feeds a direct current circuit which is connected to direct current consumers and the inverter.
- the inverter which can also be bidirectional, is used to connect to the necessary transformer and to the grid connection.
- Heat-controlled operation means that, due to the pressure conditions, an expected temperature decrease is derived over time due to the gas expansion.
- the fuel cell is controllable according to the predicted course of the. Lowering the temperature to provide the amount of heat and compensating for the lowering of the temperature if possible. If the temperature drop occurs so quickly due to the pressure conditions that exact compensation is not possible due to the thermal inertia, the aim of the control is to bring the temperature back to the old level as quickly as possible.
- the heat exchanger is designed as a heat pipe for particularly efficient heat transfer.
- gas for operating the fuel cell can be removed from the line before the odorization.
- the fuel-side device in front of the fuel cell either removes the gas before the odorization on the high-pressure or low-pressure side of the line. This considerably simplifies the gas cleaning step upstream of the fuel cell. If the fuel was removed after the odorization, a more complex gas treatment would be necessary.
- the gas for operating the fuel cell can be removed either before or after the pressure reducing device.
- a direct current and an alternating current network are simultaneously provided in the gas pressure control and measuring system.
- the fuel cell is designed as a low, medium or high temperature fuel cell.
