A method and an ocean-going vessel are disclosed for more effectively incinerating hazardous liquid wastes at sea. Intermodal shipping tank containers are filled at waste generation sites; transported to dockside and loaded above decks on an incinerator ship; taken out to sea and incinerated in horizontal, liquid burning type incinerators so that the effluents emerge horizontally. Wastes flow by gravity from containers into staging sumps located below decks, and then pumped to incinerator. Pollution abatement tanks, also below decks, collect spilled waste from containers, as well as overflow from staging sumps. Material collected in abatement tanks is pumped into staging sump, and pumped to incinerator. Fuel oil may be introduced into sumps for fueling incinerators to maintain incinerator operation when there is insufficient supply of waste. Effluents are sea-water scrubbed for cooling to eliminate thermal lift and carried promptly into sea.
A method for disposing of hazardous waste material, comprising transporting said waste material to an offshore burnsite location, incinerating said waste material in an incinerator disposed at an elevation above water level at said burnsite location, and directing the effluent discharge from said incinerator in a generally horizontal stream towards the water to substantially avoid the stream being carried aloft.
A sea-going vessel for incinerating liquid hazardous waste material, said vessel having a weatherdeck, an incinerator mounted substantially on said weatherdeck and having a substantially horizontally directed effluent discharge outlet, a staging sump for accumulating said waste material for feeding to said incinerator, and means for feeding said waste material from within said sump to said incinerator for incineration therein, whereby the products of said incineration emerge in a substantially horizontal direction from said incinerator effluent discharge outlet.
A method of disposing of hazardous waste material generated at an inland location, comprising the steps of loading said waste material in an intermodal shipping container substantially upon generation of said waste material at said inland location, transporting said intermodal shipping container to a dockside, loading said container aboard an oceangoing vessel, transporting said vessel to an offshore burnsite, feeding said waste material from said container to an incinerator at said offshore burnsite, and incineratng said waste material at said burnsite, said hazardous waste material remaining in said intermodal shipping container after loading therein until said feeding of the material to said incinerator.
