HPC – ElecTron®

The HPC – ElecTron® scheme was designed to power an HPC capture system using electricity  alone, making it entirely independent of thermal utilities on an ongoing basis. This innovative  approach taps into the natural heat produced by the capture system itself. A heat pump is  employed to raise the thermal levels needed for efficient stripping, reducing the need for any  utility other than the electricity required to operate the heat pump.  

The heat exchange is facilitated through a vapor thermocompression circuit, boasting a  substantially higher Coefficient of Performance (COP) compared to traditional heat pumps.  

The HPC – ElecTron® scheme finds its niche in applications where a thermal source is unavailable  or modifying existing plants for steam-powered capture presents logistical challenges.  

As of now, the scheme has achieved conceptual validation, and plans are in motion to elevate its  Technology Readiness Level (TRL) through targeted actions on the pilot plant

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.
