We completed a concept engineering 3D model and PFD for a client in Germany together with LP-Energy (https://www.lp-energy.de/en/) and PTN ( https://www.pompentechnieknederland.nl/). The farm-based AD installation can produce 250 Nm3/hr biogas. The primary steel reactor of 22m height with top mixer and secondary reactor of 34m diameter. In the mix pit the cattle manure is collected and pumped to the AD installation. The biogas can optionally be upgraded depending of the business plan of the client.
