How It Works

These biogas compressor series have been mainly designed for feeding biogas upgrading systems. The function of the biogas feed compressor is to elevate the pressure of the incoming biogas as well as –improving the gas quality.

As per Adicomp common process, the wet gas is sucked through a suction filter acting also as a water separator with automatic condensate drainer, then the gas passes through a suction control valve before entering into the rotary screw block.

During the gas compression process, oil circulates in a close circuit, and it is injected into the screw block to perform three main functions: lubrication, sealing and heat absorption.

Immediately after the compression, the excess of oil is removed by a gas/oil separator ; once separated, both oil and gas are cooled down by the compressor main cooler. If required the gas can be further cooled and filtered thus reducing the dew point down to 5°C/41°F, oil at 0.01mg/m3; at the end of the process the compressed gas can also be re-heated leaving the skid at a specific controlled temperature achieving the highest gas quality standards required by the customer.

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 the availability or demand of biogas.

All the components in contact with the gas are made in stainless steel or duly protected, due to the presence of H2S, CO2 and or other aggressive contaminants.

Providing adequate conditions maintenance intervals are extended at 8000 operating hours.
