GAS GATHERING AND RE-INJECTION
Gas is gathered from reservoirs and compressed in the network. Under these circumstances, the wellhead gas must be treated before being injected into the network.
Suction pressure (barA)
From 3.8 to 5.8
Suction temperature (°C)
Discharge pressure (barA)
Maximum flow rate (Sm3/hour) with suction pressure of 5.8 barA
Advantages and features of the SAFE solution:
• Highly engineered package consisting of two modules: Consisting of a skid with an electric motor coupled to a compressor from another OEM with power consumption of 680 kW at 5.8 barA suction pressure and a gas cooling system at each compression stage. The other module – designed for a safe area – is equipped with a control and power room, 15 kV to 690 V transformer, VFD, main motor circuit-breaker, an MCC for all auxiliary equipment and the control panel.
• Maximum availability and reliability: Due to the physical characteristics and composition of the wellhead gas, SAFE introduced a number of auxiliary systems to ensure maximum availability and reliability of the proposed solution: separators to remove the liquid at the inlet of each compressor stage, a gas recirculation system to control the gas flow rate by monitoring the outlet pressure and a pulsation dampening system at each compression stage.
• Highest safety standards: To ensure maximum safety of the system, the skid and all auxiliary systems were packaged inside a soundproof and weatherproof enclosure, equipped with firefighting and fire&gas detection systems.
