System and method for converting organic waste into methane and other useful products

摘要

An organic waste processing system and method for producing a slurry for the production of bio-gas, transportation fuels and chemical products, and a residual solid. The system includes (i) a hopper configured to receive sorted organic waste having contaminants from one or more sources, (ii) a separator system in communication with the hopper and configured to receive the sorted organic waste from the hopper and to remove at least a portion of the contaminants in the sorted organic waste, (iii) a complimentary liquid tank in communication with the separator system and containing complimentary liquids, (iv) a wash water liquid tank in communication with the separator system and containing wash water, (v) a product tank in communication with the separator system and configured to receive the sorted organic waste from the separator system, (vi) a make-up product tank in communication with the separator system and configured to receive the sorted organic waste from the separator system having low COD, (vii) a anaerobic digester system configured to receive the sorted organic waste from the product tank, and (viii) a programmable logic controller.

1. An organic waste processing system to produce to produce a slurry for the production of bio-gas, transportation fuels and chemical products, and a residual solid, comprising:
a hopper configured to receive sorted organic waste having contaminants from one or more sources; a separator system in communication with the hopper and configured to receive the sorted organic waste from the hopper and to remove at least a portion of the contaminants in the sorted organic waste, wherein the separator system comprises a primary centrifugal separator; a complimentary liquid tank in communication with the separator system and containing complimentary liquids, wherein at least a portion of the complimentary liquids from the complimentary liquid tank is periodically injected into the separator system upon request; a wash water liquid tank in communication with the separator system and containing wash water, wherein at least a portion of the wash water from the wash water tank is periodically injected into the separator system upon request; a product tank in communication with the separator system and configured to receive the sorted organic waste from the separator system; a make-up product tank in communication with the separator system and configured to receive the sorted organic waste from the separator system having low COD, wherein at least a portion of the organic waste from the make-up product tank is periodically injected into the product tank upon request; an anaerobic digestor system configured to receive the sorted organic waste from the product tank, wherein the anaerobic digestor system comprises a flow meter, a control valve and an anaerobic digestor tank, wherein the control valve has an open and close position; and a programmable logic controller, wherein the programmable logic controller is configured to periodically inject organic waste into the anaerobic digestor tank to enhance anaerobic digestion, wherein the programmable logic controller is configured to monitor the flow meter and to open and close the control valve to inject the organic waste into the anaerobic digestor tank.
