Abstract
Bu çalışmada mikroalg beslemeli bir anaerobik
reaktörde üretilen biyogazı yakıt olarak kullanan kojenerasyon sisteminin
ekonomik analizi gerçekleştirilmiştir. Bu sistem temel olarak şu alt
sistemlerden oluşmaktadır; mikroalglerin yetiştirildiği açık havuz,
yoğunluğunun artırıldığı zenginleştirme kısmı, biyogazın ortaya çıktığı yüksek
kapasiteli anerobik reaktör, biyogazın elektrik ve ısıya dönüştürüldüğü
kojenerasyon. Böyle bir sistemin uygunluğunu araştırmak için bir ekonomik model
verilmiştir. Ekonomik değerlendirme ölçütleri olarak net kârın bugünkü değeri,
yıllık eşdeğer, geri ödeme oranı ve geri ödeme süresi dikkate alınmıştır.
Ayrıca, teknik ve ekonomik parametrelerin sistem ekonomisine etkilerini
göstermek için duyarlılık analizi gerçekleştirilmiştir.

Abstract
In this study, economic analysis of the cogeneration system using the biogas produced in the anaerobic reactor feed by microalgae has been performed. This system consists of the following main parts; pool open channel for growing microalgae, pre-concentration section, high-rate anaerobic reactor for producing biogas and cogeneration section that biogas is converted into electricity and heat energy. An economic model to investigate the viability of such a system has been given. The present worth of the net profit, the annual equivalent, rate of return, pay-back time are considered as an economic evaluation criteria. In addition, a sensitivity analysis has been performed in order to show the effects of technical and economic parameters on the system economy.
