Simultaneous multi-variable gradient-based optimization with multi-start is performed on a 300 MWe wet-recycling pressurized oxy-coal combustion process with carbon capture and sequestration. The model accounts for realistic component behavior including heat losses, steam leaks, pressure drops,...

A pressurized oxycoal combustion process is optimized for variable thermal loading (100%–30%). The steam expansion line behavior is accurately represented based on manufacturer data. Simulations with the nominal design and nominal operation are then performed with variable loads to determine...

Simultaneous multi-variable gradient-based optimization with multi-start is performed on a 300 MWe wet-recycling pressurized oxy-coal combustion process with carbon capture and sequestration, subject to uncertainty in fuel, ambient conditions, and other input specifications. Two forms of flue...

A split concept for boilers and heat recovery steam generators (HRSG), where flue gas recycling is required for controlling the maximal temperature, is proposed for reducing the heat exchange area and/or the recycling power requirements. The concept is demonstrated in the context of an HRSG of a...

This study investigates the feasibility to synthesis methanol from its flue gas and wind hydrogen. The concept is to mitigate CO2 emission through flue gas recovery. Synthesizing methanol, on the other hand requires hydrogen at the rate of 3kmol/kmol of carbon dioxide. Electrolysis is one method...

The need to decarbonize economic production processes is undeniable and has been considered by most countries worldwide. Renewable Energy Sources (RES) and Carbon Capture and Sequestration (CCS) technologies appear among the most promising routes to the decarbonization process. We propose an...

Although a potentially useful climate change mitigation tool, carbon capture and sequestration (CCS) efforts in the United States remain mired in demonstration and development. Prior studies suggest numerous reasons for this stagnation. This article empirically assesses those claims. Using an...

Geologic sequestration has been considered as an effective and critical means for significant reductions of CO2 amounts to the atmosphere among various mitigation approaches. A carbon capture and storage (CCS) management system must be a complex system to accommodate the relevant social,...

We present exergy and economic analyses of two advanced fossil fuel power plants configurations: an integrated gasification combined cycle with advanced H2 and O2 membrane separation including CO2 sequestration (Adv. IGCC–CCS) and an integrated gasification fuel cell cycle with a catalytic...

Four different integration schemes for the Advanced Zero Emissions Power (AZEP) cycle with a parabolic trough are proposed and analyzed: vaporization of high-pressure stream, preheating of high-pressure stream, heating of intermediate-pressure turbine inlet stream, and heating of low-pressure...
