Product Offering - Purenergy CCS Capture System™

The Purenergy CCS Capture System™ is a stand alone carbon capture system that will capture CO2 from the flue gas exhaust of power plants, oil and gas processing facilities and large industrial emitters. The captured CO2 can be used for CO2 enhanced oil recovery or be stored geologically. The Purenergy CCS Capture System™ is pre-engineered, pre-built and modularly constructed by HTC's strategic partner, Kings Steel of Regina/Calgary and uses technologies developed and validated for over 15 years at the University of Regina. The system is capable of capturing up to 3000+ tons per day of CO2, and because of its modular design, is able to be manufactured, shipped and erected at the emitter sight at a much lower cost than other systems that have to be custom built on site.

How the CO2 Capture Technology Works

		HTC Purenergy CCS ™ CO2 capture system

1. The CO2 source flue-gas from the emitter plant is transferred through the duct to the CCS Purenergy plant. Prior to entering the capture plant, the flue-gas is pre-cooled to optimise the absorption process.
2. To enhance the movement of the flue-gas into the absorber tower a blower is located in the flue gas duct.
3. The blower pushes the flue-gas into the bottom of the absorption tower and upward through the tower packing material. The solvent mixture of water, amines and other chemicals cascades down through the tower and typically absorbs 85-90 percent of the CO2 in the flue-gas.
4. Once captured by the solvent the CO2 is transferred from the absorber to the top of the stripper tower, where the solvent is heated to enhance the release (de-sorption) of CO2 . The solvent containing the absorbed CO2 cascades down the stripper column through the packing material, as steam and released CO2 flow upwards.
5. The CO2 is directed to the dehydration and compression stages and on to pipeline transportation.
6. The solvent flows from the bottom of the stripper to the re-boiler (heat-exchanger) where the solvent is cooled and the heat from this exchange is transferred to steam to be used again in the stripper tower CO2 de-sorption process. The heat to operate the system is from an external source. (Normally emitter plant steam or a stand-alone steam system).
7. The 'CO2 lean' solvent solution leaves the boiler and is recycled back to the absorber tower
8. The CO2 stripped solvent then repeats the cycle by dropping down on the packing material (10) which assists in the gas-liquid absorbtion process, thus starting the CO2 capture process once again. .
