Capture research
Hydrate formation and cryogenic distillation systems
Purpose
This work aims to cost effectively develop a new CO2 capture method using hydrate formation and cryogenic distillation.
Summary
The hydrate and cryogenic CO2 capture method has the advantage of using chilled water to capture CO2 in the form of a solid hydrate, which is environmentally acceptable. This process uses minimal equipment for the release of CO2 from the hydrate. It requires low energy leading to a reduction in cost.
As a follow up of the theoretical study previously concluded, work is being undertaken to:
- experimentally investigate & validate the results obtained for the potential of hydrate and cryogenic systems to CO2 capture applications other than natural gas production i.e. Pre-combustion and Oxy-fuels;
- in both the laboratory and in a pilot plant environment, examine key parameters of the design that affect performance and cost of this technology;
- work towards obtaining optimised operating parameters; and,
- re-examine the feasibility of this technology for a range of industrial applications of interest to CRC partners and identify the limitations.
