Conceptual Design of a Novel Anaerobic Digestion Plant

Conceptual Design of a Novel Anaerobic Digestion Plant

Stopford was commissioned by a global consumer goods company to execute a conceptual design study for a novel modular anaerobic digestion plant for deployment in West Africa. Given the intended application, the plant needed to be robust, readily transportable, affordable and flexible in terms of process outputs. Accounting for the physical chemical parameters of the candidate feedstock (e.g. biological methane potential (BMP), volatile fatty acids (VFA), total solids etc) a process heat and mass balance was devised and the optimal hydraulic residence times and digestion regime calculated. The main plant items for the digestion plant were specified accordingly and an energy balance for the scheme developed. Ancillary equipment was also specified to enable treatment of process by-products.
