Disposal Methods

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U009, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
Product: Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material; Contaminated packaging: Dispose of as unused product.
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Acrylonitrile is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. Nitrogen oxides removed from effluent gas by scrubbers and/or thermal devices.
Recovering: Incineration with provision for nitrogen oxides removal from effluent gases by scrubbers or afterburners. Recovery of acrylonitrile from acrylonitrile process effluent is an alternative to disposal. Recommendable method: Incineration. Not recommendable methods: Landfill, evaporation.
A good candidate for rotary kiln incineration, with a temperature range of 820 to 1,600 deg C and a residence time of seconds. A good candidate for fluidized bed incineration, with a temp range of 450 to 980 deg C and a residence time of seconds. A good candidate for liquid injection incineration, with a temp range of 650 to 1,600 deg C and a residence time of 0.1 to 2 seconds.
/Incineration using/ ... a two stage combustion process to dispose of /acrylonitrile which/, when oxidized (one stage process), produces a flue gas containing excessive amounts of nitrogen oxides . It consists of a reduction furnace in which a high temperature reducing environment (less than stoichiometric air) converts the nitrogen oxides present into nitrogen, quench section which cools the water gas by directly contacting it with cool recycle gas, an incinerator which converts the hydrogen to water and carbon monoxide to carbon dioxide, heat recovery boiler which produces steam in cooling the flue gas and an unlined vent stack. Recycle gas cooling in lieu of air, steam, or water is an integral part of this process to minimize nitrogen oxides formation and maximize heat recovery.

PRECAUTIONS FOR "CARCINOGENS": ... Incineration may be only feasible method for disposal of contaminated laboratory waste from biological expt. However, not all incinerators are suitable for this purpose. The most efficient type ... is probably the gas-fired type, in which a first-stage combustion with a less than stoichiometric air:fuel ratio is followed by a second stage with excess air. Some ... are designed to accept ... aqueous & organic-solvent solutions, otherwise it is necessary ... to absorb soln onto suitable combustible material, such as sawdust. Alternatively, chem destruction may be used, esp when small quantities ... are to be destroyed in laboratory. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": HEPA (high-efficiency particulate arrestor) filters ... can be disposed of by incineration. For spent charcoal filters, the adsorbed material can be stripped off at high temp & carcinogenic wastes generated by this treatment conducted to & burned in an incinerator. ... LIQUID WASTE: ... Disposal should be carried out by incineration at temp that ... ensure complete combustion. SOLID WASTE: Carcasses of lab animals, cage litter & misc solid wastes ... should be disposed of by incineration at temp high enough to ensure destruction of chem carcinogens or their metabolites. /Chemical Carcinogens/

As a general technique ... treatment with sodium dichromate in strong sulfuric acid can be used. The time necessary for destruction ... is seldom known ... but 1-2 days is generally considered sufficient when freshly prepd reagent is used. ... Carcinogens that are easily oxidizable can be destroyed with milder oxidative agents, such as saturated soln of potassium permanganate in acetone, which appears to be a suitable agent for destruction of hydrazines or of compounds containing isolated carbon-carbon double bonds. Concn or 50% aqueous sodium hypochlorite can also be used as an oxidizing agent. /Chemical Carcinogens/
