— In our day, due to the both depletion of the reserves and the significant environmental problems of fossil based fuels, efforts to improve and smooth use of alternative energy sources have gained momentum. The work on alternative energy sources is mainly focused on the solar, wind and biogas fields and studies have been carried out and being continued to carry out to develop new systems and application methods in order to develop these resources. Biogas, one of the alternative energy sources, is a gas which is obtained by deterioration of biological wastes in a anaerobic environment. The pollutants in the biogas can decrease the lower heat value of the fuel and also cause corrosion and rust in the equipment and components used. Therefore, before using the biogas, it is necessary to remove contaminants in it. In this performed study, biogas has been produced from animal waste by co-fermentation method. In order to purify the pollutant gases in the produced biogas content, the effect of granular slag (an iron steel plant waste) in H2S removal from the biogas, has been experimentally investigated for different flow rates. As a result of the experiments, it was determined that the 198 ppm H2S value of the biogas measured before entering the purification tower with slag material was purified with a ratio of 76,8% and decreased to 46 ppm without methane loss.

Abstract: Increasing energy consumption, depleting fossil fuel reserves and arising environmental concerns have increased the demand form alternative energy sources. Increasing demand for the alternative energy sources also promoted the researches on producing and using cheap, clean and adequate amount of energy. As an alternative energy source, biogas has a high heating value and can be produced by agricultural, animal or biological waste through different production methods. Biogas, according to its methane content, can be used seamlessly in many areas from cooking to electricity production, from cooling to heating. In this study, annual amount of animal waste in Karabuk city is determined and the potential of biogas production from this waste is calculated. Besides, a domestic type biogas plant is designed, and cost analysis is performed. Özet: Son yıllarda artan enerji tüketimi, fosil kaynaklı yakıtların tükenmeye başlaması ve önemli çevresel sorunlara neden olması, alternatif enerji kaynaklarına olan talebin artmasını sağlamıştır. Alternatif enerji kaynaklarına olan talebin artması, ucuz, temiz ve yeterli miktarda enerji üretmek ve sorunsuz kaynak kullanımı konusundaki çalışmaları ivme kazandırmıştır. Alternatif enerji kaynaklarından biri olan biyogaz; tarımsal, hayvansal ya da biyolojik atıklardan farklı yöntemlerle üretimi mümkün olan ısıl değeri yüksek bir gazdır. Biyogaz içeriğindeki metan oranına bağlı olarak pişirmeden, elektrik üretimine, soğutmadan ısıtmaya kadar birçok alanda sorunsuz bir şekilde kullanılabilmektedir. Yapılan çalışmada, Karabük iline ait yıllık hayvansal atık miktarı belirlenmiş, belirlenen atığın biyogaz potansiyeli ortaya koyulmuştur. Çalışmada ayrıca aile tipi bir biyogaz tesisi tasarımı gerçekleştirilmiş ve maliyet analizi yapılmıştır.
