AI Technical Summary

Technical Problem

Existing biomethane production systems face inefficiencies in heat utilization, leading to suboptimal biomethane yield due to the reliance on combustion of digester gas or biomethane for heating, which reduces overall production efficiency.

Method used

A biomethane production system that recovers and utilizes heat from digester gas compression, methanation reactions, and biomethane production to heat organic waste, including the use of heat exchangers and heat transfer media to efficiently maintain the required temperature for methane fermentation.

Benefits of technology

The system achieves a high biomethane yield by minimizing the need for combustion heating, leveraging recovered heat from digester gas compression, methanation reactions, and biomethane cooling, thereby enhancing overall production efficiency.

Abstract

This invention provides a biomethane production system that can improve the yield of biomethane by recovering the heat required for methane fermentation within the system. [Solution] The biomethane production system for generating biomethane from organic waste comprises a digester 1 that digests organic waste to obtain digested sludge and digester gas, a pressurized methane high-concentration device 6 that pressurizes the digester gas with a compressor 5 and obtains biomethane from the pressurized digester gas, and a heating device 15 that recovers the heat from the pressurized digester gas and heats the organic waste with the recovered heat.
