Hypercool BioEnergy | Aftercooler for Biogas Applications

Description

The performance of biogas as a fuel depends on effective dehumidification. Saturated biogas contains water and impurities that need to be removed to avoid damage to engine equipment and pipeline and to reduce contamination of engine oil, increasing the efficiency of the whole plant and greatly reducing maintenance costs and plant downtime.

Bioenergy is renewable energy stored in organic materials such as plant matter and animal waste, known as biomass. The wide variety of biomass fuel sources include agricultural residue, pulp/paper mill residue, urban wood waste, forest residue, energy crops, landfills and animal waste. Anaerobic digestion is the process that occurs when bacteria decompose organic materials in the absence of oxygen to generate biogas.

Biogas is primarily composed of methane and carbon dioxide with smaller amounts of hydrogen sulphide and ammonia. Trace amounts of other gases like hydrogen, nitrogen or carbon monoxide are also present in the biogas. Usually the mixed gas is saturated with water vapour and may contain dirt particles.

For biogas as a fuel, most of the impurities have to be removed, as they may cause corrosion, deposits and damage to equipment. In particular biogas needs to be dried by cooling it to temperatures close to 5°C using water-cooled heat exchangers working with water chillers. Hyperchill Bioenergy is a key component of this biogas treatment process.

Hypercool BioEnergy and Hypersep BioEnergy have been specifically designed for Biogas applications. They provide safe and reliable operation in the harsh environments typically found in Anaerobic Digester and Landfill biogas production areas thanks to the use of stainless steel components specifically treated to maximize corrosion resistance.
