HPC – Genesys®

The HPC – Genesys® scheme, comprising an absorber and a stripper, represents  the simplest and most widely applicable approach. It is a traditional mainstay in HPC processes,  known for its user-friendly nature and cost-effectiveness.

Each of the alternative schemes presented by GV builds upon the HPC – Genesys® scheme,  enhancing it to meet specific goals regarding capacity, capture efficiency, energy consumption,  and considering distinct boundary conditions.

The optimal application of the HPC – Genesys® scheme is in low-capacity plants characterized by  a fully automated process. For instance, it finds a fitting application in all biogas upgrading  processes, which are typically unmanned facilities. 

Another appealing feature of the HPC – Genesys® scheme is its capacity to maximise the heat  recovery from the process. Therefore, it represents the preferred choice in situations where  thermal integration with other utilities is the primary driver.

We have a robust track record with hundreds of applications in syngas treatment and 15 in  the biomethane market, showcasing the scheme’s proven adaptability and effectiveness.

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.
