Microbox-Bio™
Biogas upgrading and RNG compression package
Microbox-Bio is a fully integrated biogas upgrading and biomethane compression package, which provides you a +99% Methane Recovery Index. Its plug-and-play technology processes up to 295 standard cubic feet per minute (scfm) of raw biogas. Hence, you can monetize your waste and supply clean Compressed Renewable Natural Gas (Bio-CNG*) for transport, power generation, and the energy industry as a whole.
* Bio-CNG is the same as Bio-NGV
Main features
The standard Microbox-Bio configuration is designed to offer you fast installation and uptime at low operation and maintenance costs.
Portable and plug-and-play
Focused on the rapid availability of Bio-CNG, its plug-and-play configuration allows for a direct connection to biodigesters. Equipped with all the elements required for a safe operation, Microbox-Bio takes only 10 days for its installation and commissioning.
+99% Methane Recovery Index
Biogas undesirable components (H2O, H2S, COV, and CO2) are removed by an integrated ZC membrane and adsorption upgrading system. Once biogas is purified, the biomethane obtained is compressed to fulfill the necessary conditions to be transported via Virtual Pipeline to a valorization site for its injection into the natural gas grid, or to be used as a heavy-duty vehicle fuel or for power generation.
Low Carbon Intensity
It refrigerates the system and supplies the kilocalories per hour (Kcal/h) that ensure the thermal operating conditions of the biodigester, without the need for an external heating system.
Proprietary compression technology
We have more than 30 years of experience and we produce 90% of our gas compression packages components. That's why we develop solutions that ensure your uptime.
Wide range of inlet pressures
Its MX 400 compressor work with inlet pressures that range from 11.6 to 14 psig. This gas reciprocating compressor adapts to different conditions and ensures the required Bio-CNG flow rate. In addition, the inlet pressures are kept constant by an axial flow regulator that does not affect the Bio CNG flow.
Scalability
Modularity, lightweight, economic transportation and easy installation turn Microbox -Bio into the most flexible solution for future expansions, relocations and the financing of the equipment.
Priority panel
A single or multiple path panel manages the Bio-CNG flow and offers an optimal dispatch capacity as well as efficient storage management.
Programmable alerts and 24/7 monitoring
Complemented by our proprietary SCADA system, a set of programmable alerts guarantees immediate preventive and corrective action on all operating parameters.
Integrated lubrication management system
Pre-lubrication pump
Ensures optimal lubrication even under intermittent operating conditions.
Automatic oil replenishment system
Provides you at least 7 days of unmanned operations.

Options
Our wide variety of configuration options maximize Microbox-Bio's benefits and boost your operation profitability.
We help to monetize your RNG
With our Virtual Pipeline, we transport your Bio-CNG by truck for injection into natural gas pipelines. Similarly, we can distribute it in container modules with a capacity of 1,000 to 1,500 Nm3 (280-420 GGE) or deliver it to filling stations to supply vehicles (NGVs). And we offer scalability and constant remote monitoring of every step in the chain beyond your facilities.
