VG series
These dry gas compression and treatment stations are designed into an easy handling skid composed of an oil-injected rotary screw gas screw block, directly coupled to an electric motor through a flexible or magnetic coupling inverter controlled.
โข VG: available operating pressures from 3.0 bar(g) to 25.0 bar(g).
HOW IT WORKS
The function of the gas feed compressor is to elevate the pressure of the incoming gas as well as improving the gas quality.
As per Adicomp common process, the dry gas is sucked in by an inlet filter and then passes through a suction control valve. During the gas compression process, the oil is injected inside the rotary screw chamber to perform three main functions: lubrication, sealing and heat absorption. The gas goes through the minimum pressure/non-return valve into an air or water cooler after cooler.
A mechanical by-pass valve is used to recirculate the gas in excess into suction to reduce the capacity from the value achieved at minimum speed of the electric motor, down to 0%. Sometimes it is necessary to install a pneumatic or electric controlled by-pass valve to have a more accurate control. When the system stops, the gas is depressurized by feeding the gas into a specific expansion buffer or bleeding it out into the atmosphere. A sophisticated control system in the adicomp series manage the operating pressure upstream or downstream the unit, and automatically adjusts compressor speed to modulate output according to the availability or demand of biogas.
Providing adequate conditions maintenance intervals are extended at 8000 operating hours.
