Process Overview

The pre-combustion capture process is a fascinating and innovative method designed to tackle the ever-pressing issue of carbon dioxide emissions. At its core, this process involves transforming fossil fuels into hydrogen and carbon dioxide (CO2) before any combustion occurs. Imagine a scenario where we can extract the harmful emissions right at the source, before they even have a chance to escape into the atmosphere. This is exactly what pre-combustion capture aims to achieve.

To break it down further, the pre-combustion process begins with the gasification of fossil fuels, which is a method that converts solid or liquid fuels into a gaseous state. This gasification process generates a synthesis gas (syngas), primarily composed of hydrogen and carbon monoxide. The next step involves a water-gas shift reaction, where steam is introduced to the syngas, leading to a chemical reaction that produces additional hydrogen and CO2. Essentially, we are separating the CO2 from the hydrogen before it can be used as an energy source.

Once the CO2 is separated, it can be captured and subsequently stored or utilized in various applications, such as enhanced oil recovery or even in the production of synthetic fuels. This not only reduces the carbon footprint of energy production but also promotes a more sustainable approach to energy consumption. The entire pre-combustion process can be summarized in the following steps:

• Gasification: Fossil fuels are converted into syngas.
• Water-Gas Shift Reaction: The syngas is treated with steam to produce more hydrogen and CO2.
