Abstract

The necessity of creating a cascade biogas plant design, in which due to the installation of a heat pump with a heat exchanger, reduces energy intensity and improves the process of fertilization, as a result of which biogas produc-tion becomes more energy-efficient. At the expense of three reactors of a cascade biogas plant with different fermenta-tion regimes, an efficient process of bioconversion with a maximum biogas output per unit biomass weight is achieved. Given the inclination and cascade of reactors, there is a self-propelled biomass displacement of reactors. Since a heat exchanger and a heat pump are connected to a mesophilic fermentation reactor in a biogas reactor, the heat is selected and sent to a biogas reactor with a thermophilic regime, which makes the fermentation process energy-efficient and economically feasible.
