T he contribution of energy in ensuring the sustainability of modern life is a primary requirement. Today, energy technologies are advancing towards the use of clean energy resources. However, it is observed that it would take long years to develop the technologies that could be adequate for global energy requirements [1]. Today, energy conversion technologies based on fossil fuels are used in power generation and to fulfill power requirements. Due to the development of energy conversion technologies based on fossil fuels, the importance of composite cycles in the reduction of exhaust emissions released to the environment per unit of generated electrical energy and the thermal efficiency of the system has increased. The combined power cycles for high efficiency and reduction of negative effects on the environment have led to the consideration of combined power cycles as ideal conventional power systems [2,3].

“…However, besides being one of the most economical options for large scale electricity generation, these conventional power plants also contribute huge amounts of greenhouse gas emissions. Therefore, performance enhancement of fossil fuel based power plants through increased efficiency and thereby reduced fuel consumption and gas emissions has received much research interest [60]. Currently, thermal efficiency of modern power plants range between 43 and 55% for subcritical and supercritical coal-fired power plants, while it is 62% for combined cycle thermal power plants [59].…”

This paper gives a brief review of energy and CO 2 emissions related topics resulting from the chemical and related industries. The main issues, challenges and opportunities are highlighted together with perspectives of process alternatives for more efficient energy consumption and CO 2 emission management. Analysis of the data indicate that not all available energy resources are being utilized efficiently, while the energy resources causing the largest emissions of CO 2 are being used in the largest amounts. Also, the chemical and related industries are among the largest consumers of energy, indicating that solutions for reduction of energy consumption and CO 2 emissions in these industries need to be investigated. Information on promising alternatives for reduction of energy consumption and CO 2 emissions are collected and a selection of them are evaluated. Also, two specific case studies involving energy intensive separation operations replaced by recently developed technologies that may achieve significant reductions in energy consumption, CO 2 emissions and total annualized costs are presented. Through these examples issues of energy need versus CO 2 neutral design, sustainable conversion, retrofit design, and process intensification for chemical and related industries are highlighted.

“…Yapılan analizler sonucunda düşük debi, yüksek türbin giriş sıcaklığı ve yüksek kompresör sıkıştırma oranının olduğu durumda bypass vanasının açılmasının, çevrimlerin verimini azalttığı tespit edilmiştir. Yüksek debi, yüksek türbin giriş sıcaklığı ve yüksek kompresör sıkıştırma oranının göz önünde bulundurulduğu durumda ise bypass vanasının kapalı olmasının çevrim verimini arttırdığı gözlemlenmiştir [10].

Nükleer, biyoyakıtlar ve yenilenebilir enerji kaynaklarının enerji üretimindeki kullanımları gün geçtikçe artsa da enerji üretiminde fosil yakıt kullanımı yaygın olarak devam etmektedir. Fosil yakıtların daha verimli bir şekilde kullanılmasını sağlayan en iyi seçeneklerin başında kombine çevrim santralleri gelmektedir. Brayton ve Rankine çevrimlerinin birleştirilmesinden oluşan bu santraller bir taraftan fosil yakıtları daha verimli kullanırken, diğer yandan çevreye daha az zarar vermektedir. Bu çalışmada doğalgazla çalışan bir kombine çevrim santralinin enerji ve ekserji analizleri, santralin gerçek operasyon verileri kullanılarak gerçekleştirilmiştir. Ortam sıcaklığının ve basıncının sırasıyla 25,4 °C ve 98,1 kPa olduğu şartlarda gerçekleştirilen analizler sonucunda, santralin ekserji verimi % 61,2 olarak bulunurken, en yüksek ekserji kaybına sahip olan bileşen 89 MW ile yanma odası olmuştur. Ekserji verimi en yüksek santral bileşeni ise % 96,4 ile yoğuşturucu olarak tespit edilmiştir. Santralden elde edilen toplam güç 205 MW olarak hesaplanırken Brayton çevriminin gücü 134 MW, Rankine çevriminin gücü 71 MW olarak hesaplanmıştır. Ortam sıcaklığı ile gaz türbini giriş sıcaklığının arttırılmasının etkileri bu çalışmada ayrıca incelenmiştir.
