In developing the gas field is designed and technical infrastructure, through which will be capable of providing a resource to the place of consumption.For this laid pipelines that transport natural gas.This assists it in moving natural reservoir pressure, but at large distances and under the influence of different hydraulic resistance in the pipeline to maintain an optimal movement speed becomes impossible.Artificially provide transportation within specified parameters allows the compressor station, thanks to which the backbone network is not only to supply gas to consumers, but also to carry out training of energy raw materials.There are different types of plants that differ in size, principles of operation and service requirements.
device compressor station
main equipment for a compressor station may include different sets of details to ensure efficient operation of the system under certain conditions.The primary device in terms of the installation of equipment, is the knot of his connection to the pipeline.In addition, the compressor station is equipped with cameras receiving and launching the pipeline cleaning system.To ensure the cleaning process uses a whole range of devices, including a dust collector filters and separators.The function of providing gas transportation take the gas pumping units and allows the cooling system to maintain the optimal parameters of the carrier.It is also used for maintenance of the station valves, devices for piping, accessories and the main control board.
Classification compressor stations
usually pumping devices are divided into groups, depending on the type of the resource served.In most cases the compressor station is oriented for use in gas pipelines, but there are also air model.Gas stations provide compressive support to a certain level of pressure, and then move it to further processing, special objects.Air plants allow to receive the compressed air, which can be used for smaller-scale works.For example, to provide a pneumatic functions, as well as reactions and processes that require oxygen.In turn, the gas station are subdivided into three groups: the booster linear and headaches.
Booster Station
Such stations are installed in underground gas storage facilities.The equipment performs two functions: transportation of gas from the main gas pipeline directly to the object for storage and further selection for the transfer to end-users.As a rule, the selection of a central pipeline booster station provides in the winter, after which natural gas is distributed to the subsequent supply of users.Stations of this type can be mounted on the gas field.Such use is usually justified if the reservoir pressure drops below the permissible value.The difference of the booster unit from other species is high compressive force and application in the design of more effective cleaning devices, such as separators, filters, dryers and dust collectors.As a result of booster compressor station improves the preparation of gas, which is taken from the main network, or from an underground storage facility.
Headends
Station head type used in areas that go after the gas field.The primary goal of these devices is to maintain optimal pressure natural gas for its subsequent transport of the backbone network.The fact is that during the development of the field of natural gas reservoir pressure in the pipes drops sharply.For his increase is just used main compressor station gas pipeline, which, incidentally, also has a small degree of compression.The function of such installations provides a consistent work of the whole complex of pumping units and assemblies.At the headend are special requirements for the preparation of the gas: it is purified from by-products produced by dehydration condensation, and mechanical impurities are removed.
Line station
compressor equipment line type is set on the main pipeline every 150 kilometers.The list of problems includes compressing sampled to prepare the gas pressure on the inlet and outlet.Linear Booster Station provides the best quality raw material purification technology.This is because of the high-tech equipment includes cyclones, replacing less efficient oil equivalents.
In this configuration clears the gas station at the same time from different impurities, moisture evaporates and removes mud deposits.Efficiency of a cleaning preparation varies from 85 to 98%.Filtration, which provides a compressor station depends on the flow in the conduit and the cyclone model.Linear stations may be equipped with a cyclone in an amount up to 6 units, which increases the efficiency of the gas purification.
and Operation
During operation of the compressor station provides maximum load on the equipment.This is due to the fact that the installation of impact increases with incomplete unnecessary power consumption.If several stations, for each of them to develop individual work schedule.Depending on the type of equipment, operation of compressor stations may provide and automatic control.But in any case the operator has to keep track selection parameters and the gas supply conduit through start or stop stations - of one or more.Special attention is paid to indicators of pressure - this is one of the key parameters of the normal operation of the compressor.
Maintenance
maintenance activities are closely associated with the operation of compressor stations and, for the most part, due to security requirements.In particular, train drivers must control the appearance nagaromaslyanyh deposits and remove them promptly.As a preventive measure to prevent the practice of using explosive layers of high-quality oils.With proper maintenance layer is formed not earlier than after two thousand hours of operation.To compressor station and its components do not fail prematurely, there are special measures to improve the quality of lubricant mixtures.As a result of such procedure increases the thermal stability of oils and reduced tendency to the appearance of deposits.Also in the list of mandatory measures include regular maintenance cleaning air path station.
