7.0 From Syngas to LSG: The Conversion Process.

The conversion of syngas into liquefied synthetic gas (LSG) involves several critical stages, each fundamental in ensuring the effective production of this alternative fuel.

Initially, syngas, which is primarily composed of hydrogen and carbon monoxide, undergoes a purification process.

This step is vital for the removal of impurities such as sulphur compounds and particulates that could hinder downstream processes.

By utilizing advanced filtration and scrubbing techniques, the quality of the syngas is enhanced, paving the way for subsequent chemical reactions.

Following purification, the next significant phase is methanation.

Note: Methanation is a chemical process where carbon oxides (carbon monoxide (CO) and carbon dioxide (CO2) react with hydrogen (H2) to produce methane (CH4) and water (H2O).

This reaction is a exothermic reaction (a chemical reaction that releases energy in the form of heat or light).

During this reaction, carbon monoxide and hydrogen from the purified syngas are converted into methane.

This stage is typically facilitated by catalytic processes where metal catalysts, such as nickel, are employed to aid the reaction, resulting in increased yield and efficiency of methane creation.

The success of this reaction is essential, as methane is a primary component of liquefied synthetic gas, influencing its overall energy content and combustion characteristics.

To further process methane into LSG, gas-to-liquids (GTL) technology is implemented.  GTL technology utilizes high pressure and temperature conditions to convert gaseous hydrocarbons into liquid products, enabling the condensation of methane into a storable, transportable fuel form.

The liquefaction process is critical as it reduces the volume of methane substantially, making it easier to transport via pipelines or in liquid storage tanks.

Once produced, the storage of liquefied synthetic gas necessitates adherence to safety and regulatory standards, ensuring that the gas remains in its liquid state within secure containers.

This phase highlights the importance of robust infrastructure capable of handling LSG, addressing potential risks with transport and storage.
