Simulation and Cost Analysis of Structured Adsorbent Capture Technology with Advances in Materials
Confidential 2
“Inventys is developing
technical advances that should dramatically reduce the cost of carbon capture
so that it can be
deployed worldwide.If successful, our technology
could revolutionize carbon capture.”
— Inventys Board Member Dr. Steven Chu, former US Energy Secretary and Nobel Laureate

Rapid Cycle Temperature Swing AdsorptionTHREE SIMPLE STEPS
As flue gas passes through the VeloxoTherm™ Adsorbent Structure, CO₂ clings to the adsorbent while the other gases pass through.
Step 1: Adsorption
After the structured adsorbent becomes saturated with CO₂, it is regenerated. Low pressure steam is used to release the CO₂ from the adsorbent.
Step 2: RegenerationAfter the CO₂ has been released, air is used to cool the structured adsorbent, preparing it for the adsorption step and the process is started over again.
Step 3: Cooling

CAPITAL COST ESTIMATION
Using factor methodology - based on AACE International 16R-90 with user variations based on cost factors from recently conducted FEED studies.
• Purchased Equipment Cost (PEC)
• Bare Erected Costs (BEC): PEC, supporting facilities, materials, bulks/commodities and direct and indirect labor expense
• Total Plant Cost (TPC): BEC + engineering/construction management/home office and contractor premiums, allowances and freight, process and project contingencies.
• Total Overnight Cost (TOC): TPC + pre-production costs, inventory capital, financing costs and other owner costs (where applicable).

BEC Estimation – Distributive Cost Factors
Material Cost = [a] x Equipment Costs, Labor Costs = [b] x Material Costs
In order to account for indirect costs, Inventys used a factor of 180% of direct labor expense which is consistent with the AACEi 59R-10 Recommended Practice range of between 115% and 180%.
