These gas compression and treatment stations are designed into an easy handling skid composed of an oil-injected rotary gas screw block, directly coupled to an electric motor through a flexible or magnetic coupling controlled by an inverter. They are designed using suitable materials and technologies for compressing this particular type of gas.
• HVG: available operating pressures from 3.0 bar(g) to 25.0 bar(g).
HOW IT WORKS
The gas is sucked through a suction filter that removes particles and also acts as a water separator (if required) , then the gas passes through a suction valve. All the components in contact with the gas are made in stainless steel or duly protected, due to the possible presence of aggressive contaminants in the gas. During the gas compression process, the oil is injected inside the rotary screw chamber to perform three main functions: lubrication, sealing and heat absorption. Working in a close circuit with a gas/oil receiver, oil is pressurized to flow through an oil cooler, then filtered before being injected again into the screw compression chamber.
The gas separated from the oil through a cartridge flows through the minimum pressure/no-return valve into a cooler and could be treated before leaving the package in accordance with custumer requirments.
