REACTOR AND ENERGY INTEGRATION SYSTEM FOR CONTINUOUS THERMAL OR THERMOCHEMICAL HYDROLYSIS OF ORGANIC MATERIAL

摘要

When particulate organic matter is to be subjected to anaerobic digestion, the biodegradability thereof can be facilitated by means of pretreatment of thermal hydrolysis which increases the quantity of biogas produced by more than 50% and reduces the mass of final residue by half. Compared to other processes, the proposed thermal or thermochemical hydrolysis reactor is characterized in that it operates continuously at temperatures of up to 190°C and pressures of 12 bar. The biogas produced can be combusted and can produce green electric energy. The hydrolysis reactor is heated by direct injection of steam which can be obtained from the gaseous streams produced in electricity generation and by means of an energy integration system and the hot streams can be exploited thereby making the system energy self-sufficient.
