Special Issue Information

Dear Colleagues,

In an era of constantly rising energy demand and the imminent need to address climate change, developing efficient and sustainable energy systems is a crucial global challenge. Combustion, CO2 capture, and looping technologies play an indispensable role in this endeavour. Combustion is the cornerstone of energy conversion and has been widely applied in power generation and many industrial fields. However, traditional combustion methods are the main source of greenhouse gas emissions. The urgent need to innovate combustion processes to mitigate climate change has driven the development of advanced CO2 capture technologies. Looping technologies, such as chemical looping combustion, offer a promising approach to improving energy efficiency and reducing emissions. These technologies offer attractive prospects and accelerate the construction of a more sustainable path for energy production.

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, application, and optimization of combustion, CO2 capture, and looping technologies.

Topics of interest for publication include, but are not limited to, the following:

  • Chemical looping combustion/reforming/gasification;
  • Calcium looping technology;
  • Oxy-fuel combustion;
  • High-performance CO2 adsorbent;
  • Chemical absorption enhancement;
  • Reactor design and system optimization;
  • Multi-energy complementary looping system;
  • Different combustion technologies, including coal/biomass combustion, premixed combustion and diffusion combustion;
  • Combustion characteristics of different fuels;
  • Advanced modelling approaches.

This study evaluates the technical feasibility of deploying containerized oxy-combustion power modules with integrated CO2 capture in remote Ecuadorian Amazon oil fields. Associated petroleum gas is conditioned with a 35 wt.% diethanolamine (DEA) sweetening stage specifically implemented to remove H2S and reduce acid-gas loading prior to combustion, improving fuel quality and protecting downstream equipment while increasing methane mole fraction for combustion. System efficiency is governed by stoichiometric oxygen demand, with methane requiring 2 mol O2/mol fuel and hexane requiring 11 mol O2/mol fuel; favoring methane-rich streams reduces ASU energy demand, enhances combustion performance, and lowers separation costs. The combined oxy-combustion cycle attains a thermal efficiency of 33.10% and an exergetic efficiency of 39.98%. Major energy penalties arise from the cryogenic air separation unit and the CCS train, yet operational tuning of CO2 recirculation and steam flow could raise thermal efficiency by up to 2%. The ASU produces oxygen at 96.67% purity with an energy consumption of 0.385 kWh/kg O2, while the CCS achieves 99.99% CO2 capture at 0.41 kWh/kg CO2. Sourcing gas from three production blocks provides flexibility to accommodate supply variability. The modular 272 MW unit demonstrates viability for off-grid power supply, routine flaring reduction, and scalable acid-gas valorization in frontier oilfields. Full article
