Computer Controlled Biogas Processing Plant (PBGC/CTS)
PL-560447
The "PBGC/CTS" Computer Controlled Biogas Processing Plant features two stainless steel reactors outfitted with level sensors and stirring systems, enabling flexible operation in either single-stage or two-stage processing modes. This setup supports separate digestion phases, with hydrolysis, acidogenesis, and acetogenesis occurring in the first digester, while methanogenesis takes place in the second. This separation allows for optimized conditions in each reactor.
A computer-controlled pump delivers substrate from a supply tank, equipped with a stainless steel agitator, to the first reactor. The system can run in continuous or batch mode, with an additional pump transferring the substrate to the second reactor and another moving the digestate to a collection tank, facilitating the study of post-fermentation impacts on biogas production.
Both digesters are equipped with heating jackets that use circulating hot water to regulate temperature, tailored to support specific microbial requirements. Temperature control is maintained through PID regulation, with the hot water circulating in a closed loop, heated in a dedicated tank with a heating element.
For pH regulation, two computer-controlled peristaltic pumps introduce acid or base independently into each reactor, with separate connections from the acid and base tanks. The biogas generated is passed through a silica gel drying column before reaching a measurement pipe. Here, parameters like flow rate, humidity, methane and carbon dioxide concentrations, and temperature are analyzed to assess biogas quality and energy potential.
Integrated with EDIBON’s SCADA system, this unit includes a touch screen interface and software for computer control, data acquisition, and data management, providing comprehensive monitoring and control across all process parameters.
