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 the solvent and the equipment cost and operation cost developed has demonstrated that the potential solvent with additive will save capital cost by about 16% or even 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 drop its viscosity to 5 cP would result in over 120 MM savings. Similar trend is observed in the annual operating cost. ​
