CO2 compression, liquefaction and dehydration
Lead Research Organisation:
Cranfield University
Department Name: School of Water, Energy and Environment
Abstract
The student project will provide a more fundamental answer to how impurities including water influences liquefaction, dehydration and compression processes to help enable the shipping option. Given the importance that impurities play in process performance, a thorough understanding of the thermodynamics, phase equilibria and flow behaviour will enable more efficient processes to be developed to de-risk the expected phase changes or corrosion. The researcher will be responsible for experimental and modelling studies to achieve these improvements using existing Cranfield pilot-scale facilities. This will involve:
Demonstrating the continuous operation of the pilot facility (which is part of the UKCCS Research Centre's Pilot-scale Advanced Capture Technology Facilities, www.pact.ac.uk) to understand processes such as compression, liquefaction and dehydration
Optimising the process operating conditions to facilitate the validation of flowsheet models for shipping transport.
Improving scientific understanding the inherent thermodynamic advantages of shipping transportation
This project will involve collaboration with several Industries relevant to CO2 transportation. The student will work closely with other industrial collaborator, such as PSE.

| Description | - Elastomer seals of different materials (Buna, EP, neoprene, Viton) have been characterised in a supercritical CO2 environment with presence of different impurities - Developed an understanding of mechanisms leading to boil-off gas generation of carbon dioxide near the triple point during real operations (loading, voyage, unloading) in relation to different parameters - Developed an optimisation of liquefaction processes for CO2 shipping in order to develop a sensitivity analysis and full understanding of the impact of process variables on process economics - Development of safety protocols to mitigate and study accidental leakage from the vessel during voyage |
| Exploitation Route | Further research on commercialisation of CO2 shipping to be implemented to improve the economics and safety of the process in relation to choice of suitable materials and operations Understanding of risks and propensity for accidental leakage during real operations Investigation on the Implementation of emergency release systems during marine loading |

| Results and Impact | UKCCSRC ECR Activity Fund is a small is a small fund of £1000 of which I am co-recipient with another 2 PhD students at the University of Sheffield. The fund enables us to carry an activity in May 2019 at Sheffield University and invite undergraduate students to teach them more about CCS, its importance and technicality. The conference will engage academics and professionals and it will be carried in an interactive way. The aim is to educate and raise awareness on CCS as a mitigation measure against global warming |
