Guillermo Jara, sales and process engineer at HRS, offered a technical presentation at the International Bioenergy Congress, focused on thermal transfer solutions to improve the energy balance in anaerobic digestion plants. His presentation is part of the experience of HRS, a company with more than 40 years of dedication to thermal transfer and process optimization. The presentation aimed highlight areas where heat exchangers in anaerobic digestion plants can be improved and how HRS addresses these issues.
First, Jara mentioned heating digesters with internal rings of tubes, a traditional system with maintenance and performance problems. HRS proposes a modular external recirculation solution that preheats the sludge before entering the digester, prevents sedimentation and reduces the risk of blockages. This solution is easier to maintain and minimizes downtime.
In the line of gases and cogeneration engines, Guillermo Jara highlighted the importance of recovering heat from the exhaust gases. HRS offers heat exchangers designed for this task, allowing reduce energy losses and improve plant efficiency. Biogas dehumidification was also addressed, another crucial point for the performance of cogeneration engines. HRS offers solutions for this process, from loose equipment to turnkey systems with chillers and droplet separators.
HRS's biogas chiller and heat recovery system has seen significant growth in recent years, highlighting its effectiveness in improving plant performance. It was mentioned the recirculation technology with tube-in-tube heat exchangers as a highly efficient option, especially in anaerobic digestion plants with higher amounts of fibers that can cause blockages in the exchangers.
Another critical aspect that was addressed was sludge pasteurization, with the aim of complying with hygiene regulations. HRS offers pasteurization systems that include energy recovery and a modular design that allows for simple and efficient maintenance. Likewise, the concentration of digestate was highlighted as a way to reduce sludge management costs and produce biofertilizers.
Guillermo Jara concluded his presentation by emphasizing HRS's commitment to optimizing the energy balance in anaerobic digestion and biogas plants. The company offers itself as a point of contact to provide solutions with both turnkey plants and heat exchangers, backed by its extensive experience in thermal transfer and processes. The audience had the opportunity to visit the HRS booth to obtain more information or clarify doubts.
