Our additive reduces

viscosity of  water-lean solvents and  lowers CO2 capture costs.​

OUR INNOVATION

Solving a viscosity problem

by breaking the full

hydrogen bonded network

into smaller clusters.​

The increase in viscosity during CO2 uptake is a major hurdle in making non-aqueous amine solvents a reality and achieving major cost advantages over current systems. RoCo’s innovative approach of hydrogen bonding segmentation, focuses on introducing a viscosity reducer to break the fully hydrogen bonded network into smaller clusters to solve the viscosity problem.​

 

Our preliminary results on the non-aqueous systems are extremely encouraging. The model amine systems with our additives are generally showing a decrease in viscosity of up to 50% when compared with systems without our additives upon CO2 loading. In certain cases, we have been able to access viscosities as low as 2 cP.

THE OUTCOME

Analysis reveals

significant impact

of solvent viscosity on

capital and operating

costs for CO2 capture. 

Our preliminary results on the non-aqueous systems are extremely encouraging. The model amine systems with our additives are generally showing a decrease in viscosity up to 50% when compared with systems without our additives upon CO2 loading. In certain cases, we have been able to access viscosities as low as 2 cP.​

The quantitative correlation between viscosity of solvent and equipment and operation cost developed has demonstrated that the potential solvent with additive will save capital costs by approximately 16% or more just by viscosity reduction (assuming a 50% reduction in viscosity). A hypothetical example would be a non-aqueous solvent with viscosity of 50 cP that drops its viscosity to 5 cP would result in over 120 MM savings. Similar trend is observed in the annual operating cost. ​
