Change has arrived

for biomethane with
BIOCH4NGE®

BIOCH4NGE® is the technology developed by AB for the production of biomethane from biomass, WWT and OFMSW.
Using the expertise it has acquired in the sector AB has designed a compact, modular, versatile and high-performance system able to recover and convert the gases produced by anaerobic digestion into biomethane to power vehicles. This is suitable for feeding into the grid or can be easily transported by road.

It is the advanced biogas-to-biomethane upgrading system to make your company more sustainable, taking it to the forefront in the quest to achieve a circular economy.

Project

Biomethane
the resource of the future

Biomethane is a renewable energy source consisting of over 97% pure methane. For this reason it can be fed directly into the natural gas grid or transported by road, and is aimed at the transport sector.

Change starts
with AB

BIOCH4NGE® is the innovative system created by AB – the leader in cogeneration and the energy exploitation of renewable sources – to produce biomethane using biogas derived from the anaerobic digestion of biomass, agri-food waste, organic refuse and wastewater.
Product

The upgrading that changes perspective

Biogas produced by an anaerobic digester is full of water and pollutants that have to be removed to ensure that the upgrading system works correctly, producing biomethane suitable for feeding into the network. The first stage of the process carries out this purification.

The flow is initially treated in the “Biogas Treatment” system with a first filtration process along with the elimination of the water, which is condensed by cooling with a purpose-designed chilled water exchanger. The dehumidified gas is compressed, cooled further by a second exchanger and sent to the next treatment phase. This uses activated carbons under optimal pressure and temperature conditions. By passing through the bed of activated carbons the biogas is purified of any remaining pollutants (H2S, VOCs). The “Lead-Lag” configuration of the carbons provides maximum flexibility through a series of valves to enable inverted flows and the bypassing and sectioning of the individual filter, thus ensuring reliability and continuity of service. The pre-treated and purified biogas is then ready for the upgrading process itself, i.e. the separation of methane from carbon dioxide: the gas is compressed to enable it to pass through several stages of membranes separating the CO2 from the CH4. In this way the process is optimised in terms of energy consumption and enables the production of biomethane with characteristics as needed for different uses, maximising efficiency in recovering CH4 from the biogas.

Product range

BIOCH4NGE® is available in standardised units from 150 to 1500 Nm3/h, complete with pre-treatment systems that can be used with existing biogas plants and integrated with possible extensions linked to the liquefaction of gas and the exploitation of CO2. Further solutions in different sizes can be made to measure for the Italian and international markets.

Plus

Industrial product

BIOCH4NGE® is entirely designed and produced by AB, being pre-assembled at the Orzinuovi production facility and tested before shipment to the installation site.

Soluzione modulare outdoor

BIOCH4NGE® is a solution designed for outdoor installation; available in different sizes, it guarantees the highest modularity of application.

Compactness

Being extremely compact, BIOCH4NGE® has been engineered in all respects to restrict the space required for its installation to a minimum and to simplify maintenance operations.

Plug&Play

BIOCH4NGE® is quick to install, without the need for on-site construction activities.

Sustainability

BIOCH4NGE® is a flexible solution in terms of both the quality requisites of the gas produced and the residual gas emitted into the atmosphere; in combination with secondary AB systems it ensures the total elimination of CH4 emissions.

Remote control

BIOCH4NGE® is equipped with a centralised monitoring and supervision system, produced and managed by AB, which enables the remote control of all system parameters and related production processes.

Full service

AB guarantees a “Full Service” after-sales maintenance contract providing assistance 24 hours a day, 365 days a year, remote monitoring of the system and the availability of original spare parts.

BIOCH4NGE® + ECOMAX®

BIOCH4NGE® integrates perfectly with cogeneration plants to create a “totally sustainable” energy system.

Applications

The synergy that generates energy

The need to obtain electrical energy for upgrading and heat for biology is effectively resolved with an ECOMAX® system. This can be combined with the BIOCH4NGE® system, whether fed by methane gas from the grid or by surplus biogas.

The membrane system

There are various biomethane upgrading technologies available on the market, based on different chemical and physical principles relating to gas separation. AB has chosen the membrane-based system, the most widely used worldwide, consisting of special polymeric materials with a selective permeability useful in separating CH4 and CO2. The pretreated gas is compressed over several phases and sent to different stages of membranes to optimise the operation; two stages aligned in series ensure compliance with grid specifications, while a third stage has the specific task of optimising methane recovery while simultaneously limiting emissions into the atmosphere. Through independent compressions management the control system is able to regulate the operating pressures in the separation stages, thus ensuring the required performance with the lowest possible energy consumption. Other advantages are the simplicity of the process (without intermediate phases or the use of chemicals or consumables) along with high scalability and flexibility – e.g. operation also with partial loads (ideal for possible future plant expansion).
