Digestate, a nutrient-rich substance, is potential resource of income in biogas plants. It can be utilized as soil amendment and solid biofuel due to containing inorganic organic compounds. However, concerning the environmental regulations, there requirement for further processes, including hydrothermal carbonization (HTC). Regarding selection optimum conditions from experimental data, this study proposes energetic yield performance indicator techno-economic viewpoint, taking load relative equipment size comparison into account well heating value hydrochar. The energy content hydrochar per unit mass reactor inlet, MJ/kg inlet. Among investigated data various digestates, feedstock were HTC agricultural residue (with 5.02 Energetic inlet) at 200 °C residence time 1 h with 30 % based on yields, i.e. selected process simulation. This also investigates required enabling balance simulation models. In addition proximate analysis hydrochar, characterization water important representing dissolved organics. available influences accuracy closure elemental balances addition, aspects producing 20 moisture well: impact property method balance, heat reaction compared literature values, integration concepts. SRK, PSRK, NRTL, IDEAL methods reported same value, −122 kW, duty reactor. corresponds −1.46 dry −1.74 dry-ash-free inlet reaction.
