Analiza uporabe biokompostarn za pridobivanje biometana

Žnidaršič, Primož (author), Golobič, Iztok (mentor)

V nalogi smo se osredotočili na analizo biokompostarn. Pri tem smo pogledali možnost obdelave biokompostarn za pridobivanje biometana. Na osnovi analize stanja smo analizirali nadgradnjo sistema na osnovi suhe digestacije. Kot najbolj uporabno tehnologijo smo obravnavali sistem KOMPOGAS podjetja Hitachi Zosen INOVA. Ob obravnavi suhe digestacije bi poleg biokomposta izkoristili obnovljiv vir ogljika v obliki biometana. Ocenjujemo, da se iz bioplina lahko izloči 60% CH4 in 40% CO2. Preko membranske tehnologije bi plina lahko ločili in vodili CO2 v biološko ali katalitično metanacijo z obnovljivim H2 ter tako dobili biometan.

• Title: Utilization of bio composting plants for biomethane production

Abstract

This paper is focused on the analysis of bio composting plants. Research is made for the possibility of processing bio composting plants for biomethane production. Based on the analyis of the situation, research is focused on upgrading the system on the basis of dry digestion. The most useful technology used is KOMPOGAS system made by Hitachi Zosen INOVA. Besides biocompost, a renewable carbon source would be used in the form of biomethane when using dry digestion. Estimation was made that biogas is made from 60% of CH4 and 40% of CO2. The gases could be separated via membrane technology. CO2 can be led to biological or catalytic methanation with renewable H2 to obtain biomethane.
