HPC – NovaFlash®

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.

Our Customizations

Designing Excellence

In addition to various regeneration schemes, the CO2 capture units by Giammarco-Vetrocoke can be equipped with numerous customizable features based on the specific application. Below is a non-exhaustive list of possibilities that can be adopted:

1. Number of Absorption and Regeneration Stages
The capture method can involve single-stage absorption/stripping, split stream (solution fed into the absorber at different temperatures), or dual-stage, depending on the specific application and the desired capture target.

2. Solvent Type
All formulations are based on Hot Potassium Carbonate salt dissolved in water. However, depending on the application, they can be either singly activated, doubly activated, Oxygen Proof type, or without any promoter at all.

Solution is not toxic, free from foaming and corrosion, and all solution formulations are freely available on the market and not tied to single vendors.

3. CO2 Purity
Depending on the specific requirement for CO2 purity at battery limits, a device can be installed to release any gases physically absorbed with the solution, thereby increasing the purity level of the final carbon dioxide. A further improvement can be implemented in order to increase the CO2 purity and, at the same time, reduce the CO2 loss.

4. Thermal Energy Reuse
In general, CO2 capture using the HPC (Hot Potassium Carbonate) process needs an external heat source for the solvent regeneration. However, this heat is almost entirely recovered and can be reused for DMW preheating, District Heating, or other integrations that dramatically reduce the net OpEx of the capture island.
