Our Process
At Westwin Elements, our innovative and environmentally conscious carbonyl refining process, proves our commitment to sustainability and responsible resource management.
Key Differentiators
-
Lower operational costs
-
Product flexibility
-
Diverse feed inputs
-
More than 200 years of combined carbonyl experience at Westwin Elements
-
Lower environmental impact
-
High purity products
Environmental Compliance
Reduced Energy Consumption
The carbonyl refining process is known for its energy efficiency, requiring less energy compared to traditional methods. This directly contributes to a reduction in our carbon footprint and promotes energy conservation.
Pilot Plant Process
Carbonyl Process Fact Sheet
CO Emissions for Pilot Plant and estimations for commercial scale
Pilot Scale
-
Carbon Monoxide (CO) emissions are below the Oklahoma minor source emissions level for potential to emit
-
CO is combusted to Carbon Dioxide (CO2) in the thermal oxidizer. All process streams of CO pass through the thermal oxidizer before exiting the plant.
Commercial Scale
-
CO emissions are heavily monitored and controlled through multiple redundant thermal oxidizers and flare stacks.
-
CO is recycled and purified with expected recycle rates of ~95%. The remaining 5% of CO is neutralized through the thermal oxidizer or a flare stack before being emitted as carbon dioxide.
-
CO is generated and purified on site.
Waste Streams (no solid waste for Pilot, minimal waste for dissolution)
Pilot
-
No solid waste
-
Minor gaseous waste from thermal oxidizer, mostly CO2 - As defined by the Applicability Determination from ODEQ the total potential effect of the pilot plant on the local environment is classified as a minor source.
-
Solid residue to be bagged and sold/ stored
-
No process liquid waste
Commercial Carbonyl
-
Solid residue to be bagged and sold/stored
-
Minor gaseous waste from thermal oxidizer, mostly CO2
-
No process liquid waste
Commercial Dissolution
-
Liquid waste stream to be handled by on site water treatment to align with ODEQ
-
Solid waste contained in liquid stream handled by same treatment facility
Summary of Wood and Trade-Off studies
-
The carbonyl process has a higher CAPEX, lower OPEX, and higher gross profit compared to traditional hydromet options.
-
The carbonyl process is more flexible (multiple feeds, multiple high purity and value add products: The value add is in specialty products, nickel powder with specific morphology or purity for customers, they pay above standard due to requiring difficult specifications only achievable through carbonyl.
