In the HPC – NovaFlash® scheme, the tendency of the solution to generate steam due to pressure reduction is exploited in a flash tank. Unlike the EcoEnergi® scheme, the produced steam is recompressed, using an ejector or MVR, back to the stripping column for complete regenerative reuse.
The HPC – NovaFlash® scheme is still compatible with the EcoEnergi® scheme as it has been used as a third stripping stage in some applications. This scheme allows for a thermal energy saving of up to 40-50% compared to the Genesys® scheme.
The HPC – NovaFlash® scheme is optimally suited for medium to high-capacity applications, where reducing operational expenditures (OpEx) is a priority and/or a source of live steam is available.
To date, this scheme has been successfully implemented in 10+ plants within the syngas sector, showcasing its efficiency and versatility.
