Karbondioksit hidrojenasyonu, alternatif yakıtları çevre dostu bir şekilde üretmenin umut verici bir yöntemidir. Mevcut literatürdeki araştırmacılar temel olarak çeşitli kaynaklardan gelen karbondioksiti ve su elektroliz ünitelerinden gelen hidrojeni kullanan karbondioksit hidrojenasyon sistemlerinin performansını araştırmışlardır. Bu çalışmada, metan ve güç üretmek için kombine bir kömür gazlaştırma ve metanlaştırma ünitesinin performansı araştırılmıştır. Metanasyon ünitesi için karbon dioksit ve hidrojen, kömür gazlaştırma sisteminden sağlanmaktadır. Buradaki karbondioksit ve hidrojen değerlerinin optimizasyonunu sağlamak için parçacık sürü optimizasyonu (PSO) yöntemi uygulandı. Bu nedenle yüksek miktarda enerjiye ihtiyaç duyan su elektroliz ünitesi sistemden verimli şekilde uzaklaştırılmıştır. İncelenen sistemden elde edilen sonuçlar, yılda ~946 kiloton kömür kullanarak yılda ~225 kiloton metan üretmenin mümkün olduğunu göstermiştir. Ayrıca, sonuçlar yıllık ~624.3 kiloton karbondioksit kullanımının mümkün olduğunu ortaya koymuştur. Sistem verimliliği yaklaşık %49 olarak tahmin edilmektedir.

Performance assessment of a combined coal gasification and methanation system with particle swarm optimization method

Öz

Carbon dioxide hydrogenation is a promising method of producing alternative fuels in an environmentally friendly way. Researchers in the current literature have mainly investigated the performance of carbon dioxide hydrogenation systems that use carbon dioxide from various sources and hydrogen from water electrolysis units. In the present study, the performance of a combined coal gasification and methanation unit is investigated to produce methane and power. The carbon dioxide and hydrogen for the methanation unit are provided from the coal gasification system. A Particle swarm optimization (PSO) method is applied to optimize the carbon dioxide and hydrogen values here. Therefore, the water electrolysis unit, which needs high amounts of energy is removed from the system, effectively. The results from the studied system showed that it is possible to produce ~225 kilotons of methane annually by using ~946 kilotons of coal per year. In addition, the results revealed that annual carbon dioxide utilization of ~624.3 kilotons is possible. The system efficiency is estimated at around 49%.
