Hydrate formation and cryogenic distillation systems

Capture Research
_

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 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.

The hydrate and cryogenic CO2 capture method has the advantage of using chilled water to capture CO2 in from 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.
