Slurry and biomass are stored in the liquid manure storage, an area where feeding liquid material and additional biomass quantities are fed into the system. This liquid material is pumped from the liquid storage area into the heated digester which is the main area of any biomass plant. The mix in this digester is always specific to the input materials and must be well mixed and homogenous so that the bacteria and substrates are in close contact. This ensures a high gas yield. Included in a digester’s design is a pressure protection system which adjusts to both over-pressured and under-pressured scenarios as well as a gas holder or foil covering.
When this substrate is digested it is then pumped into a larger storage tank, repository, or lagoon. In this condition, it can be used for fertilizer, bedding, or pelletized for other uses.
A combined heat and power generator (CHP), also known as a cogeneration unit, converts the biogas generated into electricity and heat. Options available from CleanCap includes world-leading high and medium speed gas engines, complete drive systems, distributed energy systems, and fuel injection systems as stand-alone systems or as part of a larger solution.
Power is generated by a CHP unit through combustion which converts the biogas into electricity. This electricity can be used to power facilities, equipment, as a heat source, or as revenue through either private or public power sale.
A flare and scrubber system is utilized throughout the disinfection process to destroy volatile organic compounds (VOCs), odors, and gases.
