Examples of the use of KNF pumps in biogas treatment systems.
Biogas is an important pillar for the energy industry in aiming for a sustainable future. Biogas produced from various organic materials such as corn stalks and liquid fertilizers is a carbon-neutral fuel since it does not use fossil fuels. However, this promising energy source also has technical challenges that require cutting-edge solutions. This involves several steps where pumps play a fundamental role, and KNF is pleased to provide the ideal technology. There are multiple challenges in the transport and compression of biogas. The raw biogas emitted from bioreactors is usually fully saturated with water and contains impurities and about 40% carbon dioxide (CO2). Furthermore, this gas is flammable and must not be released into the atmosphere as it is a potent greenhouse gas. Due to these characteristics, pumps that are highly airtight, do not affect the integrity of the medium, and can easily handle various chemicals and condensate are required.

How is safety ensured in LNG propulsion for ships?
Vessels powered by LNG are revolutionizing ship propulsion with cleaner and lower emissions technology. KNF's explosion-proof diaphragm pumps play a crucial role in ensuring safety through continuous leak testing of gas control systems, complying with strict ATEX specifications and marine certifications. Gas control systems utilizing explosion-proof diaphragm pumps must continuously monitor LNG supply and the controlled combustion process of large engines to ensure the reliability and safety of the integrated gas control system. For this reason, each safety module of the gas control system used is equipped with at least two diaphragm pumps, such as the KNF N680.1.2 Ex.
