Sentetik Yakıt Üretim Tesislerinde Isı Entegrasyonu

Abstract

Bu çalışma, metanol üretim sistemlerinde enerji yönetiminin kalitesini artırmak için termal enerjinin entegrasyonunu ele almaktadır. Bu çalışmada, optimum ısı transferi için gerekli olan minimum ısı değiştirici (HX) sayısı, sıcaklık aralıkları ve sıkıştırma sıcaklıkları dikkate alınarak, çimdik analizi yöntemi ile elde edilmiştir. Bu yaklaşım, sistem içinde üretilen atık ısının ısıya ihtiyaç duyan diğer sistemlerde kullanılmasına olanak tanıdığı için enerji tüketimini en aza indirir ve enerji geri kazanımını en üst düzeye çıkarır. Böylece sistemin devamlılığını sağlamak için dışarıya ısı girişi ve ısı kaybı miktarında ciddi bir azalma olur. Ayrıca bu çalışma, ısı entegrasyonu (HI) sonunda kömürden kaynaklanan karbon emisyonlarını ve sistemin CO2 emisyonlarını azaltma yeteneğini değerlendirmektedir. Sonuçlar, pinch analiz yöntemiyle optimize edilen ısı değiştiricisi ağının (HEN), şebeke tüketimini önemli ölçüde azalttığını ve metanol üretiminde enerji geri kazanımını arttırdığını göstermektedir. Isıl entegrasyon, emisyon azaltımlarında önemli bir artışa yol açarak süreci daha çevre dostu hale getirmiştir. Sonuç olarak bu araştırma, enerji verimliliği iyileştirmeleri ve çevresel faydalar sunan metanol üretimi ve endüstriyel süreçlerde termal enerji entegrasyonunun önemini vurgulamaktadır. Çalışma sonucunda aynı sayıda ısı değiştirici ile 4513 ton/gün olan emisyon azaltımı, ısı entegrasyonu sonunda 4890 ton/gün'e çıkmıştır.

Heat Integration in Synthetic Fuel Production Plants

Abstract

This study addresses the integration of thermal energy to enhance the quality of energy management in methanol production systems. In this study, the minimum number of heat exchangers (HXs) required for optimum heat transfer was obtained by the pinch analysis method, taking into account temperature ranges and compression temperatures. This approach minimizes energy consumption and maximizes energy recovery, as it allows the waste heat generated within the system to be used in others that need heat. Thus, in order to maintain the system, there is a significant decrease in the amount of heat input and heat loss to the outside. In addition, this study evaluated the carbon emissions from coal at the end of heat integration (HI) and the ability of the system to reduce CO2 emissions. The results show that the heat exchanger network (HEN) optimized by the pinch analysis method significantly reduces the utility consumption and increases the energy recovery in methanol production. Thermal integration leads to a significant increase in emissions reductions, making the process more environmentally friendly. In conclusion, this research highlights the importance of thermal energy integration in methanol production and industrial processes, offering energy efficiency improvements and environmental benefits. As a result of the study, the emission reduction, which was 4513 tons/day with the same number of heat exchangers, increased to 4890 tons/day at the end of heat integration.
