Depressurization of CO2-N2 and CO2-He in a pipe: Experiments and modelling of pressure and temperature dynamics
Upward and downward two-phase flow of in a pipe: Comparison between experimental data and model predictions
In order to deploy capture and storage (CCS) systems to mitigate climate change, it is crucial to develop reliable models for design and operational considerations. A key element of the system is the interface between transportation and storage, namely the injection well, where various transient...
A novel methodology for design optimization of heat recovery steam generators with flow-induced vibration analysis
Design of compact, lightweight, and robust heat recovery steam generators (HRSGs) is important for the implementation of offshore bottoming cycles. In this work, a novel methodology integrating flow-induced vibration analysis is proposed for the design optimization of HRSG. The vibration analysis...
Depressurization of CO2 in a pipe:High-resolution pressure and temperature data and comparison with model predictions
The design of safe and cost-efficient CO2-transportation systems is an integral part of CO2 capture and storage (CCS) deployment. To achieve this, accurate transient flow models capturing the occurrence of gas, liquid and solid CO2 are needed. These in turn rely on experimental validation. In this...
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...
