MEB installations offered by Biopolinex, i.e. Small Bio methane Cogeneration Plants, are an ideal solution for farms, processing plants, dairies, sawmills and all small industrial plants with biomass for biogas production. Biogas is produced in the process of anaerobic methane fermentation in mesophilic conditions (temperature in the range of 30-40 ° C) by-products of agriculture (e.g. corn and grass silage, beet leaves, etc.), as well as food and industrial waste (e.g. whey, stillage, kitchen waste).
The use of new methods of biomass preparation and flows allows for economic justification for 60 - 100 kWe class facilities.
The solutions applied allow for more favorable conditions of biogas plant operation. The methane fermentation process consists of 4 stages:
The correct course of one process depends on the correct course of the previous one. The hydrolysis process involves the decomposition of macromolecular substances, such as fats, lipids, complex sugars and proteins into simpler compounds, via enzymes produced by relevant microorganisms contained in biomass, i.e. simpler compounds, i.e. fatty acids, simple sugars and amino acids. Thanks to this process, acidogenic, acetogenic and finally methanogenic bacteria receive vital substances and may in the subsequent stages of fermentation lead to the formation of the final product, which is biogas. Because the optimum temperature for the bacteria responsible for the hydrolysis process is slightly lower than the optimal temperatures for the remaining microorganisms necessary during methane fermentation, it is good to carry out the hydrolysis process in a separate reactor under different conditions to make it as efficient as possible. Therefore, it was decided that the system developed by us would use separate tanks to carry out the hydrolysis process, which is the main innovation
Before the hydrolysis process, biomass is properly prepared, among others by crushing and pumped into the hydrolyzer. After 24 hours, the hydrolysis process it’s pumped into the fermenter. Appropriate biomass preparation and the use of the hydrolysis process allows for great freedom in the selection of the types of substrates used and their amounts. In the above technology, the biomass is mixed by pumps located outside the cuboid-shaped fermenter. The advantage is that in the event of a pump failure, you do not interfere with the fermentation process, which is an anaerobic process. Emergency pump replacement takes place outside the fermenter. Due to the hydration of biomass in the fermenter, the water from the end of the fermentation process with the remaining methane carriers is recycled to the beginning of the fermenter, which further supports efficiency in the initial stage of fermentation.
Also other solutions implemented with this technology allow for much more efficient operation of the installation in the bio methane production process. The average methane content in biogas ranges from 60 to even 75%, and this translates into lower biomass consumption by 40 - 50% compared to other technologies.
The biogas produced is standardized for high methane fuel for propulsion of cogeneration and fuel with GZ-50 parameters, or CNG compressed fuel or liquefied LNG. A biogas-powered cogenerator produces electricity and heat or, using absorption chiller, it can convert thermal energy into cold, supplying, for example, air conditioning or finding application in industrial cold stores.
Part of the process heat is directed to the biogas plant's own needs (biomass heating, maintaining constant temperature in tanks and in the technical building).
Other heat produced can be:
- use to heat facilities in the vicinity,
- use to power the absorption cooler,
- use to supply a thermoregenerative cell generating additional electricity
- sell, through a heating center, to a heating plant.
Thanks to innovative solutions, we can configure any system depending on the production needs of customers:
producing only biogas that can be purified to GZ-50 gas parameters
producing electricity and heat, with the option of adding an absorption cooler to replace process heat in the cold.
producing electricity and gas fuel.
producing only electricity.
