Waste Engine Oils

Automotive oil recycling involves the recycling of used oils and the creation of new products from the recycled oils, and includes the recycling of motor oil and hydraulic oil. Oil recycling also benefits the environment: [1] increased opportunities for consumers to recycle oil lessens the likelihood of used oil being dumped on lands and in waterways. For example, one gallon of motor oil dumped into waterways has the potential to pollute one million gallons of water. Recycled motor oil can be combusted as fuel, usually in plant boilers, space heaters, or industrial heating applications such as blast furnaces and cement kilns. Used oil re-refining is the process of restoring used oil to new oil by removing chemical impurities, heavy metals and dirt. The used oil is first tested to determine suitability for re-refining, after which it is dehydrated and the water distillate is treated before being released into the environment. Dehydrating also removes the residual light fuel that can be used to power the refinery, and additionally captures ethylene glycol for re-use in recycled antifreeze.

Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals additives for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, and removing contaminants from the engine, act as a cleaning agent, and act as an anticorrosion and cooling agent. This research effort focuses on comparative study of re-refined engine oils by extraction of composite solvent, single solvent, and acid treatment methods. Composite solvent was made up of butanol-propane and butanone; propane was used as single solvent. Different properties of refined oil and waste oil were analyzed, such as cloud and pour point, flash point, specific gravity, ash content, viscosity, moisture ratio and acid value. Results from the flash point, pour point, viscosity, specific gravity, and ash percentage were improved at different degrees, but the best results were seen by using the composite solvent with having drawback of expensiveness.

Used oil reclaiming ; Used oil re-refining ; Used oil recycling ; Waste oil re-refining ; Waste oil recycling. Re-refining is the used oil processing aiming at recovering a valuable resource of mineral base oil, being as good as or better than the virgin base stock, and from which any petroleum-based lubricant can be produced. They involve several processing steps and hydrogenation. In the entry on used oil disposal and collection, we looked at the problems associated with used oil, its use as fuel, and simple recycling.

Waste Engine Oils presents a complete description of the field of engine used oils, widely collected in the networks of services-stations and garages. It describes the manufacture of base oils in refineries, and mentions the main additives playing an essential role in the quality of the marketed finished oils. The organization of the different systems of collecting in order to obtain a waste oil regenerable or used as fuel are explained.

Его целью была Нью-Йоркская фондовая биржа, а замыслом - перераспределение богатства. За шесть дней члены группы установили в зданиях вокруг биржи двадцать семь взрывобезопасных легкоплавких контейнеров. Одновременный подрыв этих тщательно замаскированных устройств должен был создать магнитное поле такой мощности, что вся информация на магнитных носителях - жестких дисках компьютеров, в постоянных запоминающих устройствах, в резервных файлах и даже на гибких дисках - оказалась бы стерта.
