Waste oil disposal

The environmental aspects of lubricants (Kubo et al., 1999 Waara et al., 2001) often encounter problems such as human health and safety, waste oil disposal, greenhouse effect, and oil resource consumption. The fuel efficiency improvement contributed by engine oil is thus becoming increasingly important in the US and European markets (Hoshino and Nakada, 1995). Following are some ways to improve the fuel efficiency performance of an engine lubricant ...

The disadvantage involved in using these fresh-oil-lubricated vacuum pumps was the provision of fresh-oil logistics and waste oil disposal, which was cumbersome when operating many such vacuum pumps constantly. 

Used oil disposal trends include waste minimisation such as by reclaiming used fluid on site, as well as recycling of mineral oil lubricants instead of disposing by incineration. The recycling effort involves a system where spent mineral oils are collected then shipped to specialty refineries where the materials are distilled, hydrofinished, and re-refined into fresh base stocks. These re-refined materials are virtually identical to virgin feedstocks.

The disposal of waste oils is largely governed in the UK by the EPA 90. Waste oils are a Special Waste covered by Special Waste Regulations. Establishments handling more than 500 litres per annum have a duty to maintain records. There are also requirements for record keeping where waste oils contain toxic impurities and so become Special Waste .

Reconcentration of sulphuric acid A very large amount of tantalum heater surface has been installed in plants for the reconcentration of diluted sulphuric acid arising from metal pickling, oil refinery operations and from petrochemical processes producing alcohols and ketones. Since reconcentration provides a means of overcoming a waste of disposal problem, the use of such plants is expanding ... 

Stripping of hazardous substances Mercury switches and other components containing particularly hazardous substances must be removed CFCs are recovered from the cooling circuit and PU foam with special equipment and appliances with varying degrees of automation ammonia is dissolved in water and separate disposal of waste oil (from compressors). 

The chemical Industry requires vacuum pumps which are highly reliable and which do not produce waste materials such as contaminated waste oil or waste water. If this can be done, the operating costs of such a vacuum pump are low in view of the measures otherwise required for protecting the environment (disposal of waste oil and water, for example). For operation of the simple and rugged ALL-ex pump from LEYBOLD there are no restrictions as to the vapor flow or the pressure range during continuous operation. The ALL-ex may be operated within the entire pressure range from 5 to 1000 mbar without restrictions.

Waste oil Used oil which contains in excess of 1000 ppm chlorine, 5 ppm arsenic, 2 ppm disposal cadmium, 10 ppm chromium, 100 ppm lead, or having a flash point of less than 40°C is considered to be hazardous waste and cannot be burned for energy recovery or used in any way to produce fuel. Waste oil containing more than 1000 ppm chlorine is considered to be contaminated with chlorinated solvents or PCB and is designated as hazardous waste.

A part of the industrial plastics wastes (about 27 percent in 1987) were reutilized for productions of solid fuel, oil, gas. monomers and so on, A large quantity of the other plastics wastes were disposed of.
