Two-Stage Screw Compressor SSG Series

The SSG Series is a high-performance two-stage screw compressor designed for demanding gas compression applications. Thanks to the advanced HTS23 compressor element, it delivers up to 12% higher efficiency compared to conventional single-stage compressors while ensuring reliable operation at pressures up to 24.5 bar(g). The SSG Series is the ideal solution for pipeline boosting, gas network injection, turbine feeding, boiler feeding, vapor recovery, and industrial process gas applications. 

The SSG Series is available with or without integrated gas treatment systems and is designed for a broad range of industrial gas compression applications where high efficiency and reliable operation are required.

Biogas Upgrading Technologies:

  1. Membranes technology : Biogas upgrading technology based on selective gas separation, where the biogas compressor provides controlled and stable pressure for efficient membrane performance.

Power Generation:

  1. Turbines feeding: Supply of compressed biogas to turbines for reliable and efficient energy generation.
  2. Gas engine feeding: Biogas compression to the required pressure for stable gas engine operation.

Other:

  1. Vapor recovery: Recovery and compression of residual biogas vapors to improve process efficiency and reduce emissions.
  2. Boiler feeding: Controlled biogas compression for consistent boiler supply in thermal energy applications.
  1. Gas enters the SSG package through a filtration and separation system designed to remove contaminants and protect internal components.
  2. All components exposed to the process gas are manufactured from stainless steel or specially protected materials to ensure long-term durability even in aggressive operating conditions.
  3. During the first compression stage, gas pressure is increased while oil injection provides lubrication, sealing, and heat absorption.
  4. An intermediate cooling process reduces gas temperature before entering the second compression stage, significantly improving compression efficiency and reducing energy consumption.
  5. After the second stage, the compressed gas passes through cooling and separation systems before being delivered to the downstream process at the required operating pressure.
  6. The compressor is managed by an advanced control system that continuously regulates pressure, temperature, and speed, maximizing efficiency while extending maintenance intervals up to 8,000 operating hours

A two-stage screw compressor compresses gas in two successive stages rather than a single step. This approach reduces compression temperatures, improves efficiency, and enables higher discharge pressures.
