Xylenes

CAS RN: 1330-20-7

Disposal Methods

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U239 and F003, 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.
Xylene is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration.
Chemical Treatability of Xylene; Concentration Process: Biological traetment; Chemical Classification: Aromatic; Scale of Study: Full scale, continuous flow; Type of Wastewater Used: Industrial; Results of Study: Influent concn of 20-200 ppb decreased to 1.0-15.0 ppb effluent concn in survey of two municipal wastewater treatment plants.
A good candidate for fluidized bed incineration at a temperature range of 450 to 980 deg C and residence times of seconds for liquids and gases, and longer for solids. A good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 deg C and residence times of seconds for liquids and gases, and hours for solids. A good candidate for liquid injection incineration at a temperature range of 650 to 1,600 deg C and a residence time of 0.1 to 2 seconds.
The permeability of xylene in fire clay has been observed to sharply increase over a 4-day period after 24 days of normal behavior. This has been attributed to slow shrinkage of the clay which was responsible for the breakthrough. This type of breakthrough in clay would be a problem unless such materials are co-disposed with materials with higher dielectric constants.
Recommendable methods: Incineration, use as a boiler fuel, & evaporation.
