Thermodynamic Optimization and Part-load Analysis of the NET Power Cycle

Roberto Scaccabarozzi, Manuele Gatti, Emanuele Martelli

Energy Procedia > 2017 > 114 > C > 551-560

This paper performs the thermodynamic optimization and part-load analysis of the NET Power cycle (also called Allam cycle), a natural-gas-fired oxy-combustion cycle featuring 100% CO₂ capture level, very high net electric efficiency, and potentially near-zero emissions level. To determine the maximum achievable cycle efficiency and optimal cycle variables, an Aspen Plus flowsheet including accurate...

Evaluation of Five Alternative CO2 Capture Technologies with Insights to Inform Further Development

Jonathan Forsyth, Stuart Lodge, Stefano Consonni, Daniele Di Bona, more

Energy Procedia > 2017 > 114 > C > 2599-2610

The high cost of CO₂ capture using amine solvents from combustion sources such as natural gas-fired power plants remains a barrier to the adoption of CO₂ Capture and Storage (CCS) as a climate change mitigation measure. The objective of the work reported in this paper was to carry out a preliminary assessment of the potential of five alternative technologies suitable for post-combustion CO₂ capture...

Thermodynamic analysis and numerical optimization of the NET Power oxy-combustion cycle

Roberto Scaccabarozzi, Manuele Gatti, Emanuele Martelli

Applied Energy > 2016 > 178 > C > 505-526

This paper presents a thorough thermodynamic analysis and optimization of the NET Power cycle (also called Allam cycle), a natural-gas-fired oxy-combustion cycle featuring nearly 100% CO₂ capture level, very high net electric efficiency, and potentially near-zero emissions level. The main goals of this study are the systematic optimization of the cycle for the maximum efficiency, and the quantification...

Review, modeling, Heat Integration, and improved schemes of Rectisol®-based processes for CO2 capture

Manuele Gatti, Emanuele Martelli, François Marechal, Stefano Consonni

Applied Thermal Engineering > 2014 > 70 > 2 > 1123-1140

The paper evaluates the thermodynamic performances and the energy integration of alternative schemes of a methanol absorption based acid gas removal process designed for CO₂ Capture and Storage.More precisely, this work focuses the attention on the Rectisol^® process specifically designed for the selective removal of H₂S and CO₂ from syngas produced by coal gasification.The study addresses the following...

Numerical optimization of steam cycles and steam generators designs for coal to FT plants

Emanuele Martelli, Thomas G. Kreutz, Manuele Gatti, Paolo Chiesa, more

Chemical Engineering Research and Design > 2013 > 91 > 8 > 1467-1482

In this work, a recently developed optimization methodology for the design of heat recovery steam cycles (HRSCs) and steam generators (HRSGs) is applied to the design of steam cycles for two interesting coal to Fischer–Tropsch (FT) fuels plants: a FT synthesis process with high recycle fraction of the unconverted FT gases (CTL-RC-CCS) to maximize the production of liquid fuels, and a FT synthesis...

Supercritical pressure–density–temperature measurements on CO2–N2, CO2–O2 and CO2–Ar binary mixtures

Mario Mantovani, Paolo Chiesa, Gianluca Valenti, Manuele Gatti, more

The Journal of Supercritical Fluids > 2012 > 61 > Complete > 34-43

This paper presents new supercritical volumetric measurements on three binary mixtures mainly composed of carbon dioxide. The interest in the tested mixtures derives primarily from carbon capture and storage applications. In particular, CO ₂ -rich streams with low amounts of nitrogen, oxygen and argon are representative of the flows that are treated by the compression units and the purification...
