And fully continuous flow systems. The lowest priced family biodigesters are used in several countries in southeast asia, africa and latin america. They are also an effective energy alternative and are used for cooking or to produce electricity. Biogas and biomethane, are they the same or not really? Biomethane is said to be a gas from the purification of biogas. Purpose? Biogas is maximized so that it is as close as possible to so-called natural gas. This is a non-fossil renewable energy and is used as fuel or injected into our gas network for heating and cooking. Biomethane is also used to produce electricity but, on this occasion, it is still not very profitable, with only 30% efficiency when converting gas into electricity. Biogas includes 40 to 60% methane plus other components such as water, ammonia, volatile organic compounds or hydrogen sulfide. The latter makes the biogas corrosive and toxic at high levels. A purification method is mandatory to completely remove water and hydrogen sulfide from the biogas before restoration, mainly to avoid breakdown of restoration equipment, engines and boilers. Biogas is generally recovered at its manufacturing site, either by direct ignition in a boiler or by cogeneration.
The manufacture of heat and electricity. The cogeneration module consists of a gas engine that drives an alternator to produce electricity, and a system for restoring heat lost by the engine block and in the fumes. Cogeneration also allows us to valorize 35 to 40% of the primary energy of biogas in the form of electricity, even up to 85% of the total, also taking into account the restoration of the heat produced by the cogeneration module and system Singapore Phone Number losses. . Direct combustion boilers : undoubtedly the easiest part to use biogas, which is burned for the production of heat on site or channeled for final use in the form of gas or heat. Cogeneration engines of electricity and heat : this is the standard use of biogas in france, it has good energy production efficiency: about 85%, with 35% of the production of electricity and 50% of the generation of heat. However, heat restoration still requires the existence of outlets close to the place of biogas generation or limited at the time. What gas turbines are : for installations with a large installed turbine capacity, biogas can be incinerated in gas turbines and thus transformed into electricity; for small energies, “microturbines” are available.
Energy efficiency is low at 30%, but turbines need relatively less care than motors. Injection into the natural gas network : the biogas is purified and nourished, then designated biomethane, before being distributed into the natural gas network and for the same uses as the latter, such as cooking, heating, or compressed before being used as fuel. For automobiles. The injection of biomethane is also limited by the network's natural gas consumption rate in summer in the months of may-september. The use of projects may be affected. The choice of equipment the choice of power restoration mode depends on the biogas manufacturing context , activity conditions , treated substrates , etc. It is better to go for a restoration solution where the energy potential of biogas can be fully utilized to the maximum. It may be suitable for a combination of restoration methods, such as electricity and injection.
