Dynamic Analysis of Energy Recovery Utilizing Thermal Storage from Batch-Wise Metal Casting
The thermal exergy contained in the liquid metal in ferroalloy production makes it an interesting source for energy recovery. The heat released during casting is rarely utilized today. This work investigates the feasibility of continuous power production from batch wise ferroalloy casting using an...
Comparing Three Methods for Design Analyses of Rankine Cycle for Waste Heat Recovery from Natural Gas Compression
This study applies three methods for design of Rankine cycles utilizing waste heat in the oil and gas industry. The methods differ in the level of detail of heat exchanger model applied and in the flexibility with respect to heat exchanger design. All the methods involve formulating a constrained...
Gradient Based Design Optimization of a Radial Inflow Turbine
The expander is one of the key components of an ORC as the cycle efficiency strongly depends on the expander efficiency. This paper presents a method for design optimization of a radial inflow turbine (RIT) using a mean-line model. The novelty of this work lies in the equation-based formulation of...
Techno-economic comparison of three technologies for precombustion CO2 capture from a lignite-fired IGCC
This paper compares the techno-economic performances of three technologies for CO2 capture from a lignite-based IGCC power plant located in the Czech Republic: (1) Physical absorption with a Rectisol-based process; (2) Polymeric CO2-selective membrane-based capture; (3) Low-temperature capture...
Plate heat exchanger optimisation model - 2019 update
A novel methodology for Rankine cycle analysis with generic heat exchanger models
A new approach to the identification of high-potential materials for cost-efficient membrane-based post-combustion CO2 capture
Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, this paper presents a new approach to identify membrane materials with a...
Comparison of Rankine cycle and trilateral flash cycle for power production from low temperature heat sources
A Comparison of Post-combustion Capture Technologies for the NGCC
Four different post-combustion capture technologies are compared for the same NGCC (electric efficiency 58.1% without CO2 capture). The technologies are aqueous amine, polymeric membranes, a low temperature sorbent and Ca-looping. The effect of 40% Exhaust Gas Recirculation (EGR) is compared for all...
