Siloxane removal is crucial in biogas upgrading processes to prevent damage to engines and catalysts caused by silicon dioxide deposits formed during combustion. Effective removal methods include adsorption, absorption, and biological treatment, each with varying efficiency and cost implications depending on the specific application and siloxane concentration in the biogas stream.

Combustion is a chemical process where a substance reacts with oxygen to release energy in the form of heat and light, typically resulting in the formation of new chemical compounds. It is a fundamental reaction in energy production, transportation, and various industrial processes, playing a critical role in both natural and engineered systems.

Adsorption is a surface phenomenon where molecules or atoms from a gas or liquid adhere to a solid or liquid surface, forming a thin film. This process is critical in various applications, including catalysis, water purification, and gas storage, due to its ability to selectively concentrate substances from mixtures.

Adsorption

Absorption is the process by which one substance takes in or assimilates another substance, often involving the transfer of energy or matter. It plays a crucial role in various scientific fields, including physics, chemistry, and biology, where it affects phenomena such as light absorption, nutrient uptake, and sound attenuation.

Absorption

Biological treatment is a process that uses microorganisms to decompose organic matter in wastewater, transforming it into harmless byproducts. This environmentally friendly method is essential for reducing pollutants and maintaining ecological balance in water bodies.
