Brazed plated heat exchangers for biogas

Biogas is a naturally occurring, renewable energy source generated by the breakdown of organic matter. Municipal waste (including food waste), animal waste slurry, sewage, residues from forestry products and agricultural crops, and industrial residues can all be converted into biogas and used as an energy source.

SWEP for biogas conditioning

To render biomass useable, it must undergo extensive purification treatment. It can be dried, purified of pollutants, and separated from by-products, including CO₂ and H₂, which can in turn be liquified for storage and transportation and sold, along with the purified bio-methane. SWEP brazed plate heat exchangers (BPHE) are a key component in a wide array of biogas conditioning technologies.

Converting waste into energy

Useful by products, such as CO_2,H₂, or methane (CH₄), can be utilized. For example, CO₂can be captured, liquified, and stored; or valorized and sold as a refrigerant to food and beverage companies, greenhouses, or other industries. Purified bio-methane can be liquefied, stored, and transported to an injection point, where it can be sold. Our Bio-CO₂can be captured, liquified, and stored, and later sold as a refrigerant, as food-grade CO₂ for food and beverage companies, to greenhouses, or to other industries. The growing demand for Bio-H₂also makes it easy to sell.

Meeting the demands of biogas installations

Brazed plate heat exchangers (BPHEs) are crucial to nearly all biogas conversion systems, from the least complex to the most. SWEP has extensive experience dimensioning heat exchangers for demanding biogas installations, including cleaning, conditioning, liquefaction and regasification of biogas, as well as carbon capture and storage (CCAS). Our comprehensive portfolio of BPHEs includes durable solutions for continuous operation across a wide span of temperatures, with capacities up to 150 tons/day.
