Biogas recovery.
Cogeneration equipment and pretreatment systems.
Energy use of biogas.
The most efficient way to take advantage of the biogas obtained from waste treatment is to use it on-site, where it is produced, to produce renewable electricity and heat through cogeneration. The circle of optimal use of resources is closed in the simplest way, saving costs, energy and CO2 emissions.
Altare is an equipment manufacturer specialized in cogeneration with biogas.
Our solutions include:
- Cogeneration modules with unit powers ranging from 15 kWe to 710 kWe.
- Biogas pretreatment and drive systems.
- Pre-assembled plants of up to 1.4 MW in different formats.
Altare compact cogeneration modules
We design and manufacture in Spain a wide range of compact cogeneration modules. Equipment that integrates the gas motor-generator and the heat recovery system in the same frame, along with complete electrical cabinets and an advanced control system.
A cogeneration plant concentrated in a single piece of equipment, which is delivered assembled and tested, ready to operate.
Installing cogeneration has never been so simple and fast.
Our compact modules give you:
- Performance and reliability: we use industrial gas engines from renowned manufacturers such as LIEBHERR, MAN or SCANIA, which combine the best performance with proven reliability and durability.
- Flexibility: with fifteen power levels between 15 and 710 kWe and open or cabin versions, we can offer the optimal solution for each project. We also offer the possibility of designing custom configurations and integrating equipment in a container or shed.
- Independence: we use open control systems, not PLCs with proprietary code that make you a prisoner of the supplier. State-of-the-art systems developed by the best European specialists in motor-generator control.
- Quality: our equipment is designed and built in Spain with the highest quality standards. We use the best materials and first-class systems and components, and we rely on the knowledge acquired through long and varied experience.
- Service: We offer direct support from the factory, without intermediaries. With its own Technical Office and Technical Service. Your equipment will be cared for by the engineers and technicians who designed and built it.
Container plants
When it is necessary or convenient to install equipment outdoors, integration in a container is often the solution.
Altare designs and builds containerized plants tailored to each project. From small units of 30 or 50 kWe to Twin Pack containers with two generators and a combined power of up to 1.4 MW. The complete plant is modeled in 3D and analyzed with the client to adapt the approach and construction details as much as possible.
We also design containerized plants designed for overseas transport or for remote locations where it is critical to minimize on-site work and associated risks, as well as plants in special prefabricated sheds that offer more flexibility in dimensions than a container solution.
Biogas conditioning
The conditioning of biogas before its use in engines and other equipment reduces efficiency losses and breakdowns to a minimum, prolonging the useful life of the entire installation. It is an investment that recovers quickly and reports great benefits in the short, medium and long term.
Altare has designed and built standardized systems for biogas pretreatment that adapt to the needs of small-scale plants and equipment (up to 1.4 MWe / 600 Nm3/h). Economical and effective systems for the elimination of humidity and contaminants, as well as for the adjustment of temperature and pressure:
- Condensation dehumidification.
- Activated carbon filtering to eliminate siloxanes and sulfur.
- Temperature adjustment.
- Drive and pressure adjustment.
Standardized capacities: 30-60-100-180-250-320-470 and 600 Nm3/h.
Turnkey installations
In addition to equipment and systems, Altare has the capacity and experience to build turnkey facilities for the conditioning and use of biogas in cogeneration. From sizing and preliminary design, to assembly, commissioning and legalization of complete plants:
- Previous and detailed engineering.
- Design and manufacturing of equipment and systems.
- Assembly in plant and connection to facilities.
- Commissioning.
- Documentation and administrative procedures.
Everything from a single supplier.
