Biological gas (biogas) is a substance that consists of carbon dioxide (40%) and methane (60%). Swamp gas, mine gas, sewer and methane are considered its analogues.
If we take manure as an example, then if a ton of this biological waste is formed at the enterprise per day, from this amount of material you can get about 50 m3 gas, or 100 kW of electric energy, or 35 liters of diesel fuel. Equipment for the production of biogas pays off in two to three years, and when using other types of raw materials, the period can be even less - about a year and a half.
Benefit from a biogas plant
Installation for biogas production will bring the company not only monetary profit. There are indirect benefits to its use. For example, it will cost much less than pulling a power line, gas pipeline, creating lagoons or backup diesel generators.
Biogas plants are modern bioreactor complexes. They work with minimal cost and high efficiency. Basically, equipment for biogas production is installed on the basis of livestock enterprises, complexes for processing agricultural products and other waste.
The purpose of the biogas plant
Typically, biogas plants are used in waste recycling food industry and agriculture. Thanks to such equipment, it is possible not only to use recycled materials, but also to improve the environmental situation in production and processing zones.
In addition, an additional source of energy resources is provided. In fact, equipment for the production of biogas reduces the cycle of the cycle of substances many times, from several years to several weeks.
Components that a biogas plant should include
- Homogenization capacity.
- Reactor.
- Raw material loader: solid or liquid.
- Gas holder.
- Stirrers.
- The system of combining fuel and water.
- Gas system.
- Separator.
- Pumping station.
- Control devices.
- Instrumentation with visualization.
- Safety system.
Biogas Production Technology
Raw materials are periodically fed into the reactor using a loader or pump station. A reactor is a reinforced concrete tank, insulated and heated, equipped with mixers. It contains beneficial bacteria that feed on waste and produce biogas in the course of their life.
In order for the bacteria to be constantly viable, they must be fed with raw materials, provide a temperature of no higher than 35 degrees, and stir from time to time. The gas generated in the process is accumulated in a special storage (gas tank), and then after passing through the cleaning system it is fed to the end point, to the boiler or electric generator. The reactor is completely sealed and safe.
Biogas use
Biogas is used as fuel for generating heat, steam, electricity or for refueling cars. Equipment for biogas production can also be installed as a treatment plant at poultry farms, farms, meat processing plants, distilleries and sugar factories.
For new enterprises, the use of such a plant will significantly reduce start-up costs, since it will be possible not to spend money on laying a power line, gas pipeline,Do not install diesel generators or build waste storage tanks. As a result, capital costs are reduced by about 30-40% of the cost of equipment for biogas production.
