Production and Utilization Stage Analysis of Biogas: Case of IZAYDAS Plant
Öz: This study investigates size and operating condition effects on energy production efficiency, greenhouse gas (GHG) mitigation and economic potentials in production and utilization stages of a biogas system. In IZaYDaS plant, efficiencies of biogas production and electricity generation are found to be 28 % and 20 % independently from operating scheme, respectively. When these results are compared to a small capacity plant without an automatic control keeping the biogas system at or close to favorable conditions for fermentation and a lower quality electricity generator, both biogas and electricity production efficiencies are found to be lower showing the importance of operating conditions and size on energy production efficiency. organic waste processing is the major contributor to the GHG mitigation potential followed by fossil electricity and then chemical fertilizer replacement. Economically, liquid fraction of digestate is the major source of income due to its high amount followed by solid fraction of digestate and electricity sold to the grid. When different utilization paths are investigated for biogas, it is found that direct utilization of biogas has a higher GHG mitigation potential and favorable energetically.

Öz: Bu çalışma bir biyogaz sisteminin üretim ve kullanım aşamalarındaki boyut ve işletme koşullarının enerji üretim verimi, sera gazı salınımının azaltılması ve ekonomik potansiyele etkisini incelemektedir. İZaYDaŞ tesisinde, biyogaz ve elektrik üretim verimleri işletim planından bağımsız olarak sırasıyla %28 ve % 20 olarak bulunmuştur. Bu sonuçlar, biyogaz sistemini fermentasyon prosesi için optimum ya da optimuma yakın koşullarda tutan bir kontrol sistemine sahip olmayan düşük kapasiteli bir biyogaz tesisi ile karşılaştırıldığında, hem elektrik hem de biyogaz verimleri işletme koşullarının ve boyutun enerji üretim verimi üzerindeki etkisini gösterir şekilde düşük çıkmıştır. İncelenen tesiste, organik atıkların işlenmesi ve ardından fosil yakıt ve kimyasal gübre kullanımının ikame edilmesi sera gazı salınımlarının düşürülmesinde ki önemli faktörlerdir. Ekonomik olarak, elde edilen sıvı gübre ardından katı gübre ve şebekeye satılan elektrik gelir kaynaklarını oluşturmaktadır. Biyogaz için farklı kullanım yolları incelendiğinde, biyogazın doğrudan kullanımı enerjetik açıdan daha tercih edilir ve sera gazı azaltma potansiyelinin daha yüksek olduğu bulunmuştur.
