CO2 Reduction

Your Problem:

You must reduce your CO2 emissions being generated from fuel combustion.

Our Solution:

Quadrise Canada has a process, Multi-fuel Combustion Sequestration Technology (MCST®), covered under patent CA2505449 which we license to our customers, that captures 100% of your CO2 from your combustion applications.

Who We Help (Our Customers):

If you are burning a hydrocarbon (e.g. petroleum coke, coal, oil, heavy fuel oil, or natural gas) in your boiler to generate steam, and must capture CO2, then we have a solution for you.

Our solution is for those in the Power, Refining, Upgrading, Thermal Heavy Oil (e.g. SAGD), Mining Oilsands, Petrochemical and Metallurgical Industries.

How does Multi-fuel Combustion Sequestration Technology (MCST®) work?

In the MCST® process, hydrocarbons are burned in an oxygen enriched flue gas recirculation process, heat is removed, water of combustion and ash are recovered, SOx and NOx can be removed (optional), and the CO2 is captured and sequestered to benefit enhanced oil and gas recovery operations.

This diagram shows an MCST® configuration based on a sulfur, nitrogen, and ash containing fuel where a "carbon capture ready" existing facility is converted. The NOx and sulfur dioxide emission controls are removed, and the stack to atmosphere is closed. The basic configuration is that all combustion gases are injected into the reservoir.

Fuel is combusted in a conventional steam generator or boiler with a recirculated stream of flue gas augmented with oxygen gas, and flame temperatures are kept in typical combustion ranges. Oxygen levels are controlled to a minimum.

The boiler cools the gases to around 260°C. Particulates are removed in the electrostatic precipitator (ESP) and ash is recovered for metals recovery. The ESP is not required if natural gas is burned. The gas is cooled to below 60°C with a recirculating stream of water in the quench tower. Both the particulate removal system and the quench tower are conventional devices that have been used in the metals smelting industry for over 50 years.

The flue gas travels through several stages of compression and cooling, where most of the water is removed. The gas is compressed to injection pressures of several thousand kpa depending upon the circumstance. Trace water is removed through triethylene glycol or molecular sieve dehydration equipment. The gas compression and treating section uses conventional technology that has been practiced by the acid gas injection industry for 20 years.

Where is MCST® applied?

The technology would be applied at Steam Generating Power Stations and Thermal Heavy Oil facilities. An ideal application is where nitrogen is used for enhanced profitable hydrocarbon recovery (where oxygen is vented as a waste product) and where CO2 injection for enhanced oil recovery is desirable.

The primary market under development is Canada, however, the technology is being patented in the USA, Venezuela, the EU, Middle East, Indonesia and other nations. MCST® will be sold on a license and royalty basis.

Key Features and Benefits of the MCST® technology are:

Proven conventional equipment
  • Minimizes technical risk
  • Ability to overhaul and reuse existing facilities to achieve a reduced CO2 footprint at a competitive cost versus amine type systems
Captures 100% of CO2
  • Avoid CO2 penalties or create CO2 credits, enhanced hydrocarbon recovery application or gas cap re-pressurization
Recovers water of combustion
  • Less water demand from the environment; can replace desalination plant water
Co-generates Nitrogen from the oxygen plant
  • Can be used for enhanced hydrocarbon recovery operations
Captures 100% of SO2, NOx and Ash
  • Eliminates emissions; faster permitting
