Halogenated Waste Disposal

Halogenated refers to a chemical compound or mixture that contains halogen atoms, i.e. fluorine, chlorine, bromine, or iodine. Bonding to carbon the halogens form a class of compounds called covalent halides, i.e. they are not electroylytic in nature. Some other terms for these compounds are halocarbons (halogenated hydrocarbons), chlorocarbons and chlorofluorocarbons (CFC’s, a class of molecules containing chlorine, fluorine, and carbon).
Chlorinated solvents include the following: chloroform, chlorobenzene, trichloroethylene, carbon tetrachloride, chlorinated fluorocarbons, methylene chloride (dichloromethane), tetrachloroethylene (perchloroethylene), 1, 1, 1-trichloroethane (methyl chloroform, chlorothene). There used to be many industrial and commercial applications for the halogenated solvents due to their excellent ability to dissolve oils, their fast evaporation rates and their chemical stability (they are not flammable). Major uses in cleaning were e.g. as dry cleaning fluids, degreasing solvents, electrical cleaning solvents, inks and paint strippers. Solvent wastes are often segregated into halogenated and non-halogenated waste because it costs more to dispose of halogenated materials and because halogenated wastes are sometimes incompatible with other wastes.
Because halogenated organic solvents are often environmental and health hazards and even human carcinogens, the use in open applications has been banned worldwide. However in the view of several cleaning experts the application of perchloroethylene (PER, PERC) in modern sophisticated air tight plants is still useful for especially difficult cleaning problems, because high quality results can be achieved for very complex geometries with minimum energy input at short process times.risk management process platinum property management successful project management victory capital management program management job description powerstone property management practice management broadway management bayview asset management sonyentertainmentnetwork id management workflow management one call care management stakeholder management cedar management group project management professional certification project management steps the coi management plan aims to chronic pain management tag management asset management companies lead management sedgwick claims management services solano property management guardian asset management stormwater management waste management customer service number bieck management environmental management hayley management mangold property management moderation management games management evernest property management century property management api management waste management kennewick contract management software waste management michigan trinity property management debt management management interview questions app management brookfield asset management stock learning management systems property management albuquerque best money management app www waste management amg property management nursing management which item is included in the nims management characteristic of accountability construction management jobs southern property management which of the following most accurately describes data lifecycle management (dlm)? health information management jobs nester property management sony account management progressive management time management games goodwin management monday project management national incident management system rushmore loan management services llc absence management login kids anger management which of the following is true about the management of conflicts of interest? hoa management
