Due to the growing energy shortage worldwide, as well as unhealthy and environmentally harmful energy sources, there is an increasing need for renewable energy sources that are in line with the principles of sustainable development. And their use does not destroy the environment: this is also the case with the energy extracted from biogas!
The establishment of Biogas plants primarily fulfills an environmental protection task and can also generate income and energy in the meantime.
However, this new energy proves to be a useful investment only if we pay attention to the details, including the implementation of reliable control technology used in biogas technology!
New energy? Why is the old one not good?
More and more people live on Earth. We consume more and more energy. However, the increase in energy consumption puts a greater strain on our dying environment. The burning of coal, natural gas and the storage of nuclear waste have such an environmental impact that we have to look for alternative energy sources.
Healthy, green, organic. Trending expressions of the 21st century that leave a positive impression on us. After all, they do not destroy the environment or our health. Due to rising energy prices and non-renewable energy sources, we are looking for solutions!
How does biogas become energy?
When visiting neighboring countries, you must have often seen biogas power plants on livestock farms. In our country, such biogas plants are mainly built with tender support. Their primary purpose is energy production.
Biogas is a natural substance that is produced during the fermentation of various organic materials (fertilizer, agricultural, industrial or municipal materials) and is used in block heating power plants.
But why?
Nowadays, it is mainly used for the production of electricity and thermal energy. Biogas was initially used for heating purposes, as well as for the treatment of organic matter created on farms; however, since the 1990s, it has already been used for energy purposes, during which electricity is also produced in biogas plants.
The remaining valuable end products are composted or used for other agricultural purposes. If a suitable technology is chosen during the production, and at the end of the process it is closed with a fermentum compression, then the carbon sources can be restored with agricultural waste, and compost can be produced from it with the right technology.
Why is it advantageous to use a biogas plant?
The energy produced with biogas does not depend on the weather, and the energy produced from it is environmentally friendly, so there is no need to count on the greenhouse effect, since it does not produce carbon dioxide. With its help, we have to deal with less organic waste.
What makes a biogas plant economical?
The economics of a biogas plant largely depends on the cost of the raw materials used, the efficiency of the selected technology, and the operating costs. From how many hours it operates in a year or how much electricity it can produce.
Furthermore, success also depends on the possibility of selling the thermal energy produced by the biogas plant. But above all, from the reliable control technology involved in the processes!
Biogas plant with appropriate control technology
The operation of biogas plants must be constantly checked! Precise regulation and continuous measurement are the keys to success. An excellently functioning control unit capable of handling hundreds of data points; registration of the amount of raw materials; analysis of the temperature of the fermenters, the amount and composition of the biogas produced; it’s all an ongoing task. But thanks to PLC programming, several types of communication can run in parallel.
The machines operating in the plant (pumps, mixers, cogeneration equipment) must work properly at all times. This is not controversial. In order for a biogas plant to operate efficiently and with low labor costs, well-functioning control technology is necessary to control the processes!
