SYSTEM FOR GATHERING GAS FROM A GAS FIELD COMPRISING A HIGH EFFICIENT HIGH PRESSURE COMPRESSOR

摘要

A system includes a high pressure compressor having a gas input and a gas output. The gas input is coupleable to a gas field for receiving a gathered gas with a first gas pressure, and the gas output is coupleable to a gas export system for providing the gas with a second gas pressure, which is higher than the first gas pressure, to the gas export system. The system also includes a measuring unit coupled to the gas input. The measuring unit measures an input mass flow value indicative of an input mass flow at the gas input. The system also includes a mass flow control unit that is coupled to the measuring unit for receiving the measured input mass flow value and the gas input for controlling the input mass flow such that the measured input mass flow value corresponds to a set point input mass flow value.

1. A system for gathering a gas from a gas field, the system comprising:
a high pressure compressor comprising a gas input and a gas output, wherein the gas input is coupleable to the gas field for receiving the gas gathered from the gas field with a first gas pressure, wherein the gas output is coupleable to a gas export system for providing the gas with a second gas pressure to the gas export system, and wherein the second gas pressure is higher than the first gas pressure; a measuring unit coupled to the gas input, wherein the measuring unit is configured to measure an input mass flow value that is indicative of an input mass flow at the gas input; 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, wherein the first low pressure compressor is connected to the gas input for providing the gas to the gas input with a first mass flow; 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, wherein the second low pressure compressor is connected to the gas input for providing the gas to the gas input with a second mass flow; and a mass flow control unit, wherein the mass flow control unit is coupled to the measuring unit for receiving the measured input mass flow value, wherein the mass flow control unit is further connected to the first low pressure compressor for controlling the first low pressure compressor, and 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 such that the measured input mass flow value corresponds to a set point input mass flow value.
