  • the gas pressure inside the gas field decreases in a short time interval, such that central high pressure compressors and low pressure wellhead compressors are used from the beginning of the gathering of the gas from the gas field.
  • the low pressure wellhead compressors and the high pressure central compressor are configured as separate and independent subsystems.
  • the low pressure wellhead compressors and the high pressure wellhead compressor may form independent and separated units.
  • the high pressure central compressor is optimized for a small range of inlet pressures and inlet mass flow values.
  • the low pressure wellhead compressors are optimized for individual ranges of respective inlet pressures and mass flows.
  • Each low pressure wellhead compressor thus produces an output pressure and an output mass flow of gas without considering the small range of inlet pressures and mass flow of gas at which the high pressure central compressor works efficiently.
  • a variation of the gas pressure in the gas field does not affect the efficiency of the low pressure wellhead compressors dramatically, whereas the efficiency of the subsequent high pressure central compressor is affected dramatically during pressure changes.
  • the gathering of the gas is thus inefficient if the high pressure central compressor is not working under an efficient working point for which the high pressure central compressor is configured for (e.g., the inlet gas pressures and inlet mass flow of the high pressure central compressor vary).
  • the present embodiments may obviate one or more of the drawbacks or limitations in the related art.
  • an efficient gas gathering system for gathering gas from a gas field is provided.

  • gas e.g., natural gas
  • gas may be gathered from a conventional gas field or from an unconventional gas field, in which tight gas, shell gas or coal bed methane gas is gathered.
  • the high pressure compressor is installed between the gas field and the gas export system.
  • the high pressure compressor is adapted for receiving the gas from the gas field with a first pressure (e.g., approximately 10 to 14 bars) and adapted to compress the gas up to a second gas pressure of approximately 60 to 90 bars used by the gas export system.
  • the high pressure central compressor may, for example, be of a centrifugal type compressor and is most suitable for the gas gathering in order to generate the high gas pressure for the subsequent gas export system.
  • the high pressure compressor includes a small efficient range regarding the inputted mass flow and input pressure in which the high pressure compressor works efficient. Due to changes in inlet conditions, such as in the mass flow and in the inlet gas pressure, a high impact on the operation efficiency is caused.
  • the gas export system includes, for example, a pipeline system for transporting the gas to a desired destination.
  • the export gas system may also include a gas power plant for generating electricity or further gas treatment systems.
  • the measuring unit is coupled to the gas input of the high pressure compressor and is adapted for measuring a variety of parameters that are indicative of the input mass flow of the gas at the gas input of the high pressure compressor. For example, the measuring unit measures the input mass flow value (e.g., kg/s). Additionally, the measuring unit may measure the first gas pressure of the gas at the gas input and the second gas pressure at the gas output. The measuring unit is also adapted for measuring the output mass flow at the gas output of the high pressure compressor. Additionally, the measuring unit may measure the composition of the gas as well as the temperature of the gas at the gas input and the gas output of the high pressure compressor.
  • the input mass flow value e.g., kg/s
  • the measuring unit may measure the first gas pressure of the gas at the gas input and the second gas pressure at the gas output.
  • the measuring unit is also adapted for measuring the output mass flow at the gas output of the high pressure compressor. Additionally, the measuring unit may measure the composition of the gas as well as the temperature of the gas at the gas input and the gas output of the high pressure
  • the measured values are provided to the mass flow control unit.
  • the mass flow control unit compares the measured values (e.g., the input mass flow value) with a given set point input mass flow value. If there is a difference between the input mass flow value and the set point input mass flow value, the mass flow control unit controls the input mass flow value such that the input mass flow value corresponds to the set point input mass flow value.
  • the set point input mass flow value defines the mass flow at the gas input of the high pressure compressor, by which the high pressure compressor is working at a working point of the high pressure compressor and thus is working with the highest efficiency.
  • the working point is dependent on the pressure relation between the first gas pressure at the gas input and the second gas pressure at the gas output, the mass flow of the gas through the high pressure compressor (e.g., the mass flow at the gas input) and the rotational speed of the high pressure compressor.
  • a set point input mass flow value is thus given for running the high pressure compressor at a working point of the high pressure compressor and hence at a best efficiency.
  • a deviation of the input mass flow value causes a severe effect on the efficiency of the high pressure compressor. For example, if the measured input mass flow value differs dramatically to the set point input mass flow value (e.g., at given first and second gas pressures), compressor surge may occur.
  • the mass flow control unit is adapted for reducing the deviation of the measured input mass flow value from the given set point input mass flow value.
  • the mass flow control unit may control various subsystems for influencing the input mass flow of the gas at the gas input.
  • the mass flow control unit may control upstream installed low pressure compressors, delivery valves or a mass flow in a return flow tubing and/or a mass flow of a bypass tubing, which will be explained in more detail below.
  • a predetermined and desired input mass flow at the gas input of the high pressure compressor is adjustable by the mass flow control unit such that the high pressure compressor is working approximately at a working point of the high pressure compressor.
  • the efficiency of the high pressure compressor and hence the gathering of gas from a gas field is more efficient.
  • the system includes a first low pressure compressor that is connectable to a first wellhead arrangement of the gas field for receiving the gas from the first wellhead arrangement.
  • the first low pressure compressor is connected to the gas input for providing the gas to the gas input with a first mass flow.
  • the system also includes a second low pressure compressor that is connectable to a second wellhead arrangement of the gas field for receiving the gas from the second wellhead arrangement.
  • the second low pressure compressor is connected to the gas input for providing the gas to the gas input with the second mass flow.
  • the mass flow control unit is connected to: a) the first low pressure compressor for controlling the first low pressure compressor; and b) the second low pressure compressor for controlling the second low pressure compressor such that the first mass flow and the second mass flow are controllable for controlling the input mass flow at the gas input.
  • Each wellhead arrangement is connected to a borehole through which gas of the gas field is gathered.
  • a gas field may include a plurality of boreholes.
  • a respective wellhead arrangement is attached to each borehole for gathering gas.
  • Each wellhead arrangement is connected to a respective low pressure compressor. For example, if a wellhead arrangement delivers gas with approximately 1 to 4 bars to the low pressure compressor, the low pressure compressor increases the pressure up to approximately 5 to 20 bars. By increasing the pressure, a sucking effect is achieved, such that the gas is sucked out of the respective borehole, so that the respective mass flow through the low pressure compressor is also increased.
  • screw-type or reciprocating compressors may be used. These kinds of compressors are relatively insensitive to changes in inlet conditions.
  • the compressors have a large operating range and may easily handle a wide range of inlet pressure variations and inlet mass flows variations under which an effective operation may still be provided.
  • the measuring unit is adapted for measuring each mass flow and pressure at a respective gas input of a respective low pressure compressor and at a gas output of a respective low pressure compressor. This measured data is sent to the mass flow control unit.
  • the mass flow control unit also receives the information of the input mass flow at the gas input of the high pressure compressor. If more or less mass flow is needed at the gas input of the high pressure compressor, the mass flow control unit controls the respective low pressure compressors (e.g., the first low pressure compressor and the second low pressure compressor).
  • the mass flow control unit receives the information of the working points of the respective low pressure compressors. For adjusting the desired input mass flow of the high pressure compressor, each low pressure compressor is thus controlled under consideration of respective working points such that each low pressure compressors is operated more efficiently. The overall efficiency of the system is thus increased.
  • the system includes a first delivery valve that is connectable to a first wellhead arrangement of the gas field for receiving the gas from the first wellhead arrangement.
  • the first delivery valve is connected to the gas input for providing the gas to the gas input with a further first mass flow.
  • the system further includes a second delivery valve that is connectable to a second wellhead arrangement of the gas field for receiving the gas from the second wellhead arrangement.
  • the second delivery valve is connected to the gas input for providing the gas to the gas input with a further second mass flow.
  • the mass flow control unit is connected to: a) the first delivery valve for controlling the first delivery valve; and b) the second delivery valve for controlling the second delivery valve, such that the further first mass flow and the further second mass flow are controllable for controlling the input mass flow at the gas input.
  • the first and second delivery valves may be installed between the respective first and second wellhead arrangement and the respective first and second low pressure compressors.
  • the first and second delivery valves may be installed behind (e.g., downstream) of the respectively first and second low pressure compressors.
  • the further first mass flow and the further second mass flow of the gas gathered from a respective borehole is adjustable and controllable individually, such that a desired input mass flow of the gas at the gas input of the high pressure compressor is adjustable.
  • gas may be gathered without using low pressure compressors.
  • the delivery valves are installed downstream of the wellhead arrangement in order to control mass flow from the respective wellhead arrangement to the gas input of the high pressure compressor.
  • the system includes a return flow tubing that is connected to the gas output for bleeding off a part of the gas from the gas output and is connected to the gas input for injecting the part of the gas in the gas input.
  • the mass flow control unit is coupled to the return flow tubing for controlling the bleeding off of the part of the gas from the gas output and for controlling the injecting of the part of the gas in the gas input such that the input mass flow at the gas input is controllable.
  • a part of the gas may be bled off from the gas output and injected at the gas input, so that the input mass flow is increased at the gas input.
  • a control valve that is controllable by the mass flow control unit may be installed.
  • the mass flow control unit may act as a supervisory system and controls the anti-surge system.
  • the input gas parameters e.g., the input mass flow of the gas
  • the upstream located systems such as the low pressure compressors (e.g., wellhead compressors)
  • the anti-surge system for the high pressure compressor is safer and more efficient.
  • the system further includes a bypass tubing that is connected to the gas input for bleeding off a further part of the gas from the gas input.
  • the mass flow control unit is coupled to the bypass tubing for controlling the bleeding off of the further part of the gas from the gas input such that the input mass flow at the gas input is controllable.
  • the bypass tubing may bleed off the gas from the gas input (e.g., to the environment or to a further use), for example, into a gas generator. By bleeding off the gas from the gas input, the input mass flow is thus reduced until the desired set point input mass flow value is adjusted.
  • the high pressure compressor of a gas gathering system is controlled and operated more efficiently.
  • predetermined set point input values e.g., set point input mass flow values
  • the high pressure compressor may be optimized for predetermined operating ranges in order to run more efficiently at the given set point input mass flow values.
