Carbon Disulfide

CAS RN:75-15-0

Disposal Methods

[40 CFR 240-280, 300-306, 702-799 (7/1/2006)] Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P022, D003, F005, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

Carbon disulfide is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. A sulfur dioxide scrubber is necessary when combusting significant quantities of carbon disulfide.

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. 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 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.

This compound should be susceptible to removal from waste water by air stripping.

Reuse: This cmpd is a very flammable liquid which evaporates readily. It burns ... to carbon dioxide (harmless) and sulfur dioxide. ... The pure liquid presents an acute fire and explosion hazard. ... If quantity is large, carbon disulfide may be recovered by distillation and repackaged for use. Recommendable methods: Evaporation, adsorption, & incineration. Not recommendable method: Landfill. Peer-review: Care. Substance very easily ignited. Landfill is not recommendable due to the high flammability. Evaporate small amt only. (Peer-review conclusions of an IRPTC expert consultation (May 1985))

Adsorption: The CS2 /carbon disulfide/ adsorption employs activated coal which adsorbs it from the mixture with hydrogen sulfide in the absence of free oxygen. An industrial installation with the capacity to regenerate as much as 80-90% of carbon disulfide contained in the gas-air mixture has been developed.
