CryoCell® Technology

Cool Energy's gas conditioning package is based on a new cryogenic CO2 capture technology

Solidifying, separating, extracting, and re-melting CO2

The CryoCell® technology extracts the CO2 contaminant from a gas stream in a liquid form suitable for geo-sequestration or other industrial applications.

In the process the temperature of the gas stream is reduced in stages before being passed through a Joule-Thomson valve that drops the pressure and reduces the temperature to below the CO2 solid formation temperature for the gas mixture. The solid CO2 is then separated from the vapour stream, which will then meet pipleline sales gas specifications.

The CO2 solids separate by gravity to the bottom of the CryoCell® separator. Heat is introduced in the separator bottom to melt the CO2, which is removed from the separator as a liquid. CO2 can then simply be pumped up to the injection pressure required for geo-sequestration. Equipment requirements and energy consumption for geo-sequestration compared to conventional technologies are relatively very low.

CryoCell® CO2 technology overview:

  • Gas sweetened by the CryoCell® technology will comply with the specifications for pipeline transportation.
  • CO2 is removed as a liquid thereby allowing low cost sequestration and elimination of greenhouse gas emissions.
  • In gas feedstocks with higher concentrations of CO2, the elimination of dedicated solvent processes and their supporting utilities permits Cool Energy's technology to function with substantially lower capital and operating costs.
  • Current and future developments of the technology are expected to result in meeting the low CO2 levels needed for LNG production.

Cool Energy's proprietary technology offers the following advantages over current CO2 removal processes:

  • Captures CO2 as a pressurised liquid allowing for low-cost geosequestration
  • Eliminates the use of chemicals
  • Lower capital and operating costs
  • Highly scalable with footprint depending on gas flow rather than CO2 content
  • Reduced weight and footprint
  • Simpler operation
  • Fewer supporting utilities
  • No corrosion concerns
  • Configuration and process flexibility to meet a range of applications
