  • Patent number: 4247321
    Abstract: A method and apparatus for obtaining fertilizing solution from fossil fueled stationary engines by adding carbon dioxide and nitrogenous compounds, derived from exhaust gases, and ozone gas derived from a generator, to water so as to produce a fertilizing solution which promotes crop growth. The method comprises direct contact of exhaust gases derived from fossil fueled combustion engines particularly natural gas fired compressors, with water solution containing ozone gas and an agent selected from the group consisting of lime, limestone, calcium phosphate and/or mixtures thereof in a scrubber, cooling the enriched water from the scrubber, recycling the cooled enriched water through the scrubber until a desired concentration of carbon dioxide and nitrogen compounds are achieved and collecting the enriched water in a storage facility.
