Capital cost is reduced
The higher gas and liquid velocities in the RFC column allow the cross-section to be reduced compared with a conventional counter-current flow contactors. Moreover, only about 40 per cent of the packing height is required with RFC technology, compared with conventional columns, to achieve the same amount of mass transfer.
Engineering cost and time may be reduced
With very large conventional columns, there’s also the cost of moving all the material to site, fabricating the column and associated infrastructure onsite, the amount of labor involved in erecting the tower, and the size of the cranes and the foundation. Shrinking the size of the absorber system offers capital cost savings beyond the cost of the equipment itself.
Reduced infrastructure costs
The RFC technology can reduce infrastructure costs with reduced plant size; reduced contactor size, smaller regenerator size, smaller pipelines. and reduced on-site erection cost (less labour, crane ratings, crane time and so on). The technology can cut in half the footprint area and reduce the height of the gas-liquid absorption column by 50 to 60 per cent, compared with conventional absorption columns.
The RFC technology reduces OpEx compared to conventional contactors with solvent pulsing and enabling the use of precipitating solvents thereby simplifying the entire process flow of the whole industrial site and reducing overall energy costs. The reduced height reduces energy requirements to pump solvent to the top of the contactor and reduced energy costs of operating smaller regenerators, pumps, and less piping to transport the solvent. Foundation ratings may even be reduced.
