Biogas Plants

A biogas plant (BP) is a facility for processing bio-waste by way of anaerobic fermentation which yields biogas.

BP types

  • agricultural
  • waste

Benefits of a biogas station?

  • a stable source of income from the sale of electric power or heat as a solution to owner buildings, etc.
  • a viable solution waste disposal products (droppings, liquid manure etc.) or production waste by-products
  • quality fertilizer

What about the smell?

We use a high quality and tested material for the construction of BP. The roofing system is from the best manufacturers in Europe, such as SATTLER A.G. The smell of a biogas station is minimized when the required technological procedures are observed. It is a closed process.

We offer complete deliveries of agricultural BP to our customers for crops grown for this particular purpose and stations for the disposal of biodegradable wastes.

To customers we offers the following

  • complete “plug-and-go” delivery
  • delivery of the individual building objects
  • delivery of the individual technological facilities
  • repairs and service of all parts of the biogas station

Technology

Wet fermentation – material in tanks with solid content of up to 12%
Dry fermentation – material in tanks with solid content of 25 – 40%

The organic material decomposes without access to air which creates methane, with CO2 as the by-product.

The cogeneration unit provides the production of electric power and heat. Electric power can be distributed into the network with a small amount of power and heat required for the operation of the unit. The remaining part may be used for other needs (heating, drying etc.).

If the cogeneration unit needs to be shut down, the biogas can be eliminated in the burner of the spare heat source (boiler) or by the flare boiler.

The biogas plant is designed and delivered according to the customer’s needs – on the basis of their budget, available quantity and type of material, and the installation area.

BP with “Wet Fermentation“

Standard Equipment of BP

  • fermentation tanks
  • storage tanks
  • gas collector
  • metering vehicle, input tank
  • gas treatment and purification
  • cogeneration unit

Other BP Equipment

  • silo chute
  • sanitation
  • separation
  • separate dryer
  • fertilizer storage
  • handling technology

Standard material: droppings, liquid manure, corn silage, sugar cuttings etc.

BP with “Dry Fermentation“

A dry-fermentation BP is a gas-proof and waterproof digestion chamber where the operating volume of the chamber is approx. 800 m3 of material.

The chamber is emptied and filled by a wheel loader. The input material is injected by mixing fresh bio-waste (approx. 60% of the load) with already fermented biomass (approx. 40% of the load), and then by spraying process water on the fermented mass in the closed chamber. The BP is designed and delivered according to the customer’s needs – on the basis of their budget, available quantity and type of material, and the installation area.

Standard Equipment of BP

  • fermentation tanks
  • storage tank for process water
  • gas collector
  • gas treatment and purification
  • cogeneration unit
  • wheel loader

Other BP Equipment

  • sanitation
  • fermented product dryer
  • fertilizer storage

The entire process is controlled by an automated computer. Remote control of the BP is also available. The entire facility is safe; the key elements are protected from incorrect and unauthorized manipulation.

Micro BP with Dry Fermentation

This is a dry BPS with the output of 15 – 25kWel, designed as a container.

To provide the even production of biogas the entire fermentation device is divided by a gas-proof partition into two independent fermentation chambers with front gas-proof single-leaf doors.

There is a technology room with a separate entrance between the fermentation chambers which includes the heating distribution, catchment and treatment technology, and process water (percolate) distribution.

The internal shell of the fermentation chambers are made from a stainless material. The container is completely heat-insulated. The floor and the side walls have hot-water heating installed. A cogeneration unit provides the heat.

To start the process in the fermentation chambers a boiler for burning propane-butane will be used with a spare source and a flare boiler. The boiler is installed in the technology container.

The closed circuit of the process water provides the drainage of the percolate from the chamber, its transport to the collecting tank, pH treatment and subsequent spraying of the biomass through nozzles.

The produced biogas is transferred from the fermentation chamber to the vacuum gas container located in the protective structure above the fermentation chamber.

From the gas container, biogas is transferred to the technology container, while its qualitative parameters are adjusted, and then it is transferred to the combustion motor of the cogeneration unit using an air blower.

The entire facility can be modularly extended: the additional containers with fermentation chambers do not include a technology room.
