Biogas plants can be equipped with a combined heat and power plant that converts biogas to electricity and heat, or with the unique HoSt biogas upgrading technology. This unit is able to separate methane from the biogas with a very high efficiency, >99.5%, using membranes. After the purification, the quality of the biomethane meets the requirements of natural gas. Due to the low own heat demand (direct solid feeding + high dry solid in digester), more heat is available for other purposes.
Robust engineering, high-quality design biogas plants
Characteristic for the farm-type plants supplied by HoSt is that they are equipped with concrete, isolated tanks, furnished with a double membrane roof. The solid feeding input is equipped with vertical augers. These large augers mix the different biomass streams into a homogeneous mixture, resulting in a stable biogas process. Due to the direct feeding of the solid into the digester it is possible to digest high dry solids content. This, results in no water adding, longer retention times or smaller digesters with less own electricity and heat consumption.
Liquids, like liquid manure and liquid waste currents, are pumped directly to the digester from the existing or the new storage. Depending on the input, the installation will be adjusted and optimized to the specific situation. HoSt supplies high-quality plants that are low-maintenance and easy to control.
