HOW IT WORKS
Our natural gas compression and treatment stations are designed onto an easy handling skid, composed of an oil-injected rotary screw block, directly coupled to an electric motor. At the suction side, the dry gas is sucked, filtered and then it flows to the rotors through a control valve. During the gas compression process, oil is injected inside the rotary screw chamber to perform three main functions: lubrication, sealing and heat absorption. After the compression stage, most of the oil is removed thanks to specific filters and then the gas flows through an air cooler to lower its temperature. A mechanical by-pass valve recirculates the exceeding gas to modulate the capacity from the value achieved at minimum speed of the electric motor, down to 0%. When the system stops, the circuit is depressurized by conducting the gas into a specific expansion buffer or bleeding it out to the atmosphere.
