Compressors for the gas and biogas industry

Safety, reliability and low operating costs are the winning features of Mattei compressors for the natural gas, technical gas and biogas treatment and handling.

How to choose your compressor

Choosing an air compressor must hinge on the specific production and environmental characteristics of this industry.

Application fields of gas compressors

In order to be handled and used in different applications, gases need to “travel” within networks that transport them safely and at a certain pressure from the point of withdrawal to their final destination. This “journey” takes place thanks to their compression, carried out by means of machines with special characteristics.

Gas compressors are indispensable in the energy sector, both for upstream hydrocarbon extraction and processing applications and in electricity and heat production plants; they are also used in the chemical processing of many industries for the treatment of technical process gases.

In more recent times, gas compressors have also become protagonists in the agricultural industry, in the food industry and in waste management sector, thanks to the practice of recovering biogas generated by fermentation and transforming it into biomethane, which can be used for energy purposes.
Given the special nature of the fluids treated (natural gas, technical gas, biogas), gas compressors must be designed to ensure maximum reliability and safety, even in harsh environmental conditions such as outdoor sites with great temperature range.

Biogas industry

The biogas generated by fermentation in anaerobic digesters of animal waste, agricultural and food waste, or organic waste, is a renewable energy source that, when properly treated, can be used exactly like methane gas: it can be fed into the distribution network or used on site as fuel in boilers and cogeneration plants for the combined production of electricity and heat.

The purification treatment that transforms biogas into biomethane, called “upgrading”, consists in the elimination of impurities, contaminants and excess carbon dioxide. This is a particularly “green” practice because, in addition to using waste to produce energy, it avoids releasing large quantities of methane, a gas highly responsible for the greenhouse effect, into the atmosphere.

In these processes the compressors play a fundamental role in capturing and conveying the biogas to the upgrading system and, subsequently, to the distribution network or to the motor of the cogeneration plant. Applications dealing with biogas involve special requirements, which must also be met by the particular compressor technology.

Safety and reduction of operating costs

In gas treatment, safety is a fundamental characteristic of a compressor. To this end, Mattei gas vane compressors meet the requirements of ATEX regulations, which require the use of stainless steel instead of other metals, and the remote positioning of electronic control equipment to prevent the risk of fire and explosion.

The filtering system also guarantees excellent gas quality, while the suction valves and the constant control of flow rate and pressure eliminate the risk of leakage and ensure the supply of gas according to the demand of the energy system or the capacity of the distribution network.
In addition to these features, high performance, operational reliability over time, energy efficiency and low maintenance costs guaranteed by the vane construction design make Mattei machines the lowest Life Cycle Cost products on the market.

The benefits of Mattei compressors for gas treatment

The experience matured by Mattei in the realisation of customised compressors has allowed the company to develop machines with the ideal characteristics to operate in the treatment of natural gas, biogas and technical process gas. Below are the main ones:

  • compressors designed for different types of natural gas: sweet gas, acid gas (containing high quantities of hydrogen sulphide) and biogas;
  • systems complying with the requirements of the Atex (Atmosphères Explosives) directives;

  • reduced maintenance costs thanks to the construction design that minimises the interventions for component replacement;
  • reliability over time: Mattei compressors work at full capacity 24/7;
  • gas flow rate control at constant pressure: a particular software performs a feedback control function, before the gas is introduced into the compressor, checking that the flow rates are set according to the parameters set based on the request;
  • filtration system that guarantees excellent gas quality;
  • no yellow metal components; cast iron vanes and stators that resist wear;
  • possibility to create customised solutions, for specific applications or critical environmental conditions.
