Abstract
A gas transfer station has high pressure gas delivered in pipeline 1 and a low pressure side connected to a consumer network 14. The gas pressure is reduced by cooling in the secondary side of a heat-exchanger 3 and expansion in a machine 6. Expanded gas at lower pressure and temperature passes through a heat exchanger 8 which is one element of a cooling system with circulating pump 9 and cooling space 11. Expanded gas passes through the primary side of heat exchanger 3 and is compressed to the required discharge pressure by a compressor 12 driven by machine 6. Part of the gas leaving the compressor 12 is conducted back to the inlet of expansion machine 6 while another part is delivered through driers 5a & 5b and metering apparatus 13 into the consumer network 14. <IMAGE>
Description
SPECIFICATION
Gas transfer station
The invention relates to a gas transfer station provided with a high pressure side connected to a pipeline, and a low pressure side connected to a consumer network and with a pressure-reducing device between them.
Piped gas transmission is widely used in the natural gas industry. The necessary gas quantity transmitted by a pipeline can be realized only with the utilization of energy. Kinetic and potential energy have to be transmitted with the gas in order to transfer the gas in the pipeline from one station to another further station. The energy necessary for transmission of the gas is generated by the use of pressure-intensifying compressors. The potential energy of the gas effects the medium to be transmitted in the form of pressure. Intensity of the existing pressure - i.e. the starting pressure - is determined by the terminal pressure loss and by the existing pipe diameter.
Pressure of the gas at the location of delivery transmitted to great distance is substantially higher than the permissible consumer pressure at both the consumers connected to the intermediate and those at the end of the gas pipeline. The value of the arriving pressure generally fluctuates between 20-35 bar, while the permissible consumer pressure is between 3-10 bar. The arriving pressure is reduced to the necessary value of the consumer pressure by pressure-reducers or pressure regulators.
The pressure reduction takes place at the gas transfer stations. In the currently used technological solutions this pressure reduction is achieved in the gas transfer stations with the use of a choke valve.
No work is performed by the potential energy output of the gas. Consequently a significant part of the energy in put is lost.
The invention aims to provide a gas transfer station wherein the potential energy of the delivery pressure of the gas is utilized.
Thus the invention relates to a gas transfer station provided with a high pressure side connected to a pipeline, and a low pressure side connected to a consumer network and with a pressure reducing device arranged between them, wherein the pressure reducing device is an expansion machine (socalled detander) the outlet of which is connected to the inlet of the machine(s) utilizing mechanical work, while its outlet is connected to a system utilizing cooling energy, at least one element of which is formed as a gas cooling heat-exchanger arranged in front of the expansion machine, while another element is formed as heat-exchanger cooling the heat transfer medium of the cooling battery.
Thus the station according to the invention converts the potential energy of the gas to cooling energy and/or mechanical work by cutting out the hitherto used reducing choke valve. The cooling energy of enthalpy incidental to the isentropic process, i.e. the temperature drop is used for refrigerating industrial purposes. Thus, for instance, the demand of a cold storage tank with 300 000 kcal/h refrigerating capacity, or cold storage plant is met by a gas transfer station according to the invention where the consumer's gas requirement taking into account 12 hour per day - reaches a consumption of 20 000 Nm3/h and the extent of pressure drop reaches 1:3 expansion ratio during the same time.
At the 1:3 expansion ratio no liquid hydrocarbon condensation will occur from the piped gas which would disturb the operation of the expansion machine. This is given by the fact that the piped gas is already prepared at the feed point and it contains 94-98 % methane, the condensation temperature of which in this pressure range is around -100"C, while the gas in accordance with the preparation does not contain heavy hydrocarbon components.
The cooling energy derived at the transfer station can be economically conveyed within 5-10 km distance, in other words installation of the gas transfer station and cold storage plant is not bound to the same location.
The machine utilizing the mechanical work according to the invention is a compressor, the inlet of which is connected through the system utilizing the cold energy to the outlet of the expansion machine, while the outlet of the compressor is connected through the distributing device-partly to the consumer network and partly to the inlet of the expansion machine. In the solution according to the invention using the mechanical work produced by the expansion machine for recompression, the expansion ratio of the expansion machine can be increased, since the expansion can be reduced below the discharge pressure in the expansion machine. This technical arrangement increases the refrigerating capacity produced by the expansion machine.
According to a further preferred feature of the invention, the compressor connected with the outlet of the expansion machine may also be formed as a compressor for a conventional cooling cycle with a choke valve. This alternative construction offers the possibility for the provision of two independent cooling cycles. Within the scope of the invention the detander-connected machine performing the mechanical work may be an electric generator, which represents safety, especially in case of failure of the power supply.
Safety is ensured also by the optionai feature of the invention that the expansion machine as the pressure reducing device is provided with a by-pass pipeline fitted with a choke valve. In case of a breakdown connected with the expansion machine, or in the event that the cold storage plant does not require cooling energy, the expansion machine can be disconnected.
The main advantage of the gas transfer station according to the invention is that it converts the potential energy of the arriving gas to cooling energy and mechanical energy, easily operated with a simple expansion machine. At the same time it ensures in the simplest way the utiiization of the derived cooling energy.
A special advantage is that in this way the construction of the cold storage plant and cold storage tank becomes considerably simpler and less expensive, since they do not require costly compressor housings and compressors. Practically, only a cooling medium circulating pump and a cooling battery will be built into the cold storage plant.
The invention is described in detail by way of example with the aid of the accompanying drawings, in which:
Figure 1 is a schematic iayout of the gas transfer station according to the invention; and
Figure 2 is a schematic layout of a further gas transfer station according to the invention.
In the construction shown in Figure 1 given by way of example, the gas delivered in pipeline 1 branching off the high pressure gas network (not illustrated) is carried through parallel-connected cyclones 2a and 2b to a heat-exchanger 3, as one of the elements of the system utilizing the cooling energy. The heatexchanger3 is essentially formed as a gas-gas heat-exchanger in which the delivered high pressure gas is cooled down. As a result of the cooling the condensate developing in the high pressure gas is separated in the precipitator 4 arranged after the heat-exchanger 3. Then the high pressure gas is liberated from the vapour content in the parallel driers 5a and Sb. The so-prepared high pressure gas from driers 5a and 5b is expanded to a lower value than the output pressure in the expansion machine 6.During expansion the enthalpy and thus the temperature of the gas is substantially reduced. The condensate possibly separating from the gas flowing out of the discharge pipe of the expansion machine 6 is removed from the already low pressure gas in the precipitator 7. The cold low pressure gas is conducted through the primary side of the heatexchanger 8, forming one of the elements of the cooling energy utilizing system. The cooling battery 10 connected to the ring duct carrying the heat transfer medium provided with circulating pump 9 is linked with the secondary side of the heat-exchanger 8. The cooling battery 10 is arranged in the cooling space 11 of the cold storage plant (not illustrated).
The gas heated up in the heat-exchanger 8 transfers part of its cooling energy to the heat transfer medium, then cools it down. Circulation of the heat transfer medium by the pump 9 ensures the continuous cooling capacity of the cooling battery 10.
The low pressure gas from the heat-exchanger 8 is returned through the pipeline to the primary side of the heat-exchanger 3, where the high pressure gas admitted through the cyclones 2a and 2b is cooled down. Then the low pressure gas conducted through the primary side of the heat-exchanger 3 is recompressed by the compressor 12, connected to the outlet of the expansion machine 6, to the discharge
pressure.
A certain part of the gas heated during compression leaving the outlet of the compressor 12 is conducted back with the distributing device to the
inlet of the expansion machine, while another part is
delivered through the intermittently operating driers 5a and 5b and metering apparatus 13 into the
consumer network 14.
In the construction given by way of example - as
shown in the schematic layout - the gas is delivered to the consumer even with the traditional choke valve 15 in case of trouble in the technological apparatus, or when the cold storage plant is not in need of cooling energy.
In the construction given by way of example as shown in Figure 2, similarly to the former example, the gas - delivered through pipeline 1 branching off the high pressure gas network (not illustrated), i.e.
the prepared high pressure gas conducted through cyclones 2a and 2b and heat-exchanger 3 as well as through condenser 4 and driers 5a and 5b - is expanded in the expansion machine 6, then it is conducted through the precipitator 7 on the primary side of the heat exchanger 8 utilizing the cooling energy of the cold gas. The secondary side of the heat exchanger 8 - similarly to the former example is linked with heat transfer medium-carrying ring duct provided with circulating pump 9. The cooling battery is arranged in the cooling space 11 (formed as the deep freeze of the cold storage plant (not illustrated).The heated low pressure gas leaving the primary side of the heat exchanger 8, similarly to the former example, is conducted through the primary side of the heat exchanger 3, where a further part of the cooling energy is transferred to the admitted high pressure dust-free gas. Then the low pressure cold gas flowing through the heat exchanger 3 is conducted through the primary side of the heat exchanger 16 forming the element of the cooling energy utilizing system conducted to the secondary side of the outlet of compressor 12, then part of the already heated low pressure gas is conducted to the inlet of the expansion machine 6 while the other part through the intermittently operating driers 5a and Sb and metering device 13 to the consumer network 14.
The compressor 12 connected to the expansion machine 6 is formed as the compressor 12 of the cooling cycle containing the choke valve-fitted cooling battery 18. The heated, gaseous cooling medium leaving the outlet stub of compressor 12 is condensed in the heat exchanger 16. The cooling battery 18 ensures the cooling energy of the cold storage tank 19 of the cold storage plant (not illustrated).
The construction shown by way of example in
Figure 1 can be used to advantage in case of pressure of smalier pipeline branching. The construction shown in Figure 2 is recommended generally for pipeline pressure over 25 bars and when the demand for deep freezing exists.
