Carbon Clean

Carbon Clean  is ca CCUS company founded in 2007 in Oxford, UK. They offer a standardized, fully modular technology CycloneCC which utilizes Carbon Clean’s advanced proprietary amine-promoted buffer salt solvent (APBS-CDRMax) and rotating packed beds. 
Alternatively, Carbon Clean also offers their CDRMax solution, which is a “normal” carbon capture plant custom made for customers’ desires and utilizing the more traditional amine-based carbon capture setup. 

They claim competitive advantage based on the following:

  1. Low footprint: Compared to traditional capture methods, Carbon Clean’s CycloneCC technology requires less physical space, minimizing disruption at existing sites. They do not require any absorber tower, making their overall footprint 50% smaller than a conventional system.
  2. Modular and adaptable technology:  Carbon Clean offers modular capture units that can be easily integrated with existing industrial facilities, offering flexibility and scalability for various applications.
  3. Cost-effective solutions: Due to their advanced solver solution and smaller footprint, they can reduce up to 50% in CAPEX requirement by utilizing lower-grade materials in construction and 50% in OPEX requirement by using less thermal energy for operations.

Capture technolgy - Rotating packed beds

1. Absorbtion of flue gas with the help of rotating packed beds

The CO2-rich flue gasses are introduced into the rotating packing bed from outside in, resulting in a concurrent flow between solvent and flue gas. The solvent is introduced in the middle of the rotating packed bed.


When the packing is rotating, the liquid and the gas can move between each other more rapidly than normally. That assists with mass transfer between liquid and gas. This enhanced mass transfer allows for a higher absorption of flue gas to the liquid solvent and is forced towards the edge via centrifugal force. 
Rotating packed beds operate at hundreds of RPMs, similar to conventional pumps.

2. Rich solvent regeneration

Solvent regeneration occurs in desorption tower, adjacent to the rotating packed beds. 
The solvent is based on the Amine-Promoted Buffer Salts technology (APBS-CDRMAX), a patented Carbon Clean solvent. The company claims to achieve:

  • 20x Less corrosion and 10x less degradation 
  • Reduction in foaming and waste, leading to 50% less ongoing chemical requirement and waste disposal
  • Lower aerosols
  • 5x longer solvent life and 86% less solvent makeup

Reference projects

The Mongstad pilot project was designed to assess the environmental impact, corrosion potential and energy efficiency of the Amine-Promoted Buffer Salts solvent technology.

  • Project Dates: It ran from November 2015 to March 2016.
  • Project Goal: Its primary objective was to assess the environmental impact, corrosion potential, and energy efficiency of the APBS technology in a large-scale industrial setting.
  • Results: The pilot was deemed successful, demonstrating potential for significant cost reductions in carbon capture compared to existing methods.

Currently, CycloneCC technology is being tested at two locations 

Scotland:

  • Project Announcement: October 2023
  • Project Goal: Demonstrate CycloneCC’s ability to capture carbon emissions from a cement kiln at Altrad Babcock’s Emissions Reduction Test Facility in Scotland.
  • Partners: Carbon Clean, Altrad Babcock, and the Scottish Government
  • Duration: Expected to be 12 months, suggesting completion by October 2024.

Abu Dhabi Al Ruwais Industrial Complex:

  • Project Announcement: October 2023
  • Project Goal: Demonstrate CycloneCC’s ability to capture carbon emissions from a nitrogen fertilizer plant in the Al Ruwais Industrial Complex
  • Partners: Carbon Clean, ADNOC and Fertiglobe

Carbon Clean’s technology is being demonstrated at Tata Steel’s Jamshedpur steel plant in India, capturing 5 tonnes of CO2 per day. The modular skid mounted unit captures CO2 directly from the blast furnace gas and makes it available for onsite reuse in a variety of applications. The depleted CO2 gas is then sent back to the gas network with an increased calorific value.

  • Location: Tata Steel’s Jamshedpur plant in India
  • Technology: Carbon Clean’s semi-modular unit for capturing CO2 directly from blast furnace gas.
  • Capture capacity: 5 tonnes of CO2 per day.
  • Project Goal: Demonstrate the feasibility and cost-effectiveness of carbon capture within the steel industry.
  • Significance: The first-of-its-kind project in the global steel industry for blast furnace carbon capture in India.

Carbon Clean’s technology is in operation at the Tuticorin Alkali Chemicals and Fertilizers plant in India. 

  • Location: India
  • Technology: Carbon Clean’s semi-modular unit for capturing CO2 directly from coal-fired boiler
  • Capture capacity: 60kt CO2 per year
  • Project Goal: Utilize CO2 in the production of soda ash (sodium carbonate)
  • Significance: The first non subsidized carbon capture and utilization plant in India
