Mineralization incineration

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. 

Venmri scrubbers have been applied to control PM emissions from utility, industrial, commercial, and institutional boilers fired with coal, oil, wood, and liquid waste. They have also been applied to control emission sources in the chemical, mineral products, wood, pulp and paper, rock products, and asphalt manufacrnring industries lead, aluminum, iron and steel, and gray iron production industries and to municipal solid waste incinerators. Typically, venturi scrubbers are applied where it is necessary to obtain high collection efficiencies for fine PM. Thus, they are applicable to controlling emission sources with high concentrations of submicron PM. 

Uses. Used mineral-hased crankcase oil is mixed with other oils to produce cutting oils or other lubricating oils. It is incinerated for energy in oil burners in homes, industrial steam boilers, municipal incinerators, and rotary cement kilns. It is also used in asphalt production. 

Nickel is also found in meteorites and on the ocean floor in lumps of minerals known as sea floor nodules. The earth s core contains large amounts of nickel. Nickel is released into the atmosphere during nickel mining and by industries that make alloys or nickel compounds or industries that use nickel and its compounds. These industries may also discharge nickel in waste water. Nickel is also released into the atmosphere by oil-burning power plants, coalburning power plants, and trash incinerators. 

The vendor states that MBS stabihzes heavy metals in soil, slndges, slag, ash, baghonse dnst, and sediment. Among the heavy metals treatable by the MBS process are arsenic, cad-minm, chrominm, copper, lead, mercnry, nickel, silver, and zinc. MBS technology is applicable in the following indnstries primary and secondary smelters, battery mannfactnrers and recyclers, ferrons and nonferrons fonndries, mnnicipal solid waste incinerators, anto and metal scrap recyclers, electronic mannfactnrers, electroplaters, ceramic prodnct mannfactnrers, and mineral refiners and processors.

The amount of water may bo ascertained by drying a weighed portion in the steam bath, and noting the loss. Mineral adulterations may be detected by incinerating a known quantity of the drug, and weighing and examining the residue. 

Mineral impurities may be detested by incinerating a portion of the sample in a platinum capsule. Pure quinin leaves no residue. Or a portion of the suspected quinin may bo treated with alcohol at a gantlc heat. Quinin dissolves, whilst any mineral matter which may be present, as well os gum, starch, stearin, will romain untouched. If a portion is burned upon platinum foil, sugar and margario acid may be detected by their peculiar smoke and small... 

In more exact determinations it is necessary to subtract from the weight of the insoluble matter that of the mineral matter (sand, etc.), to obtain that of the pure cellular substance. For this purpose the filtration should take place through a dried and tared paper, the weighed insoluble matter being afterwards incinerated and the weight of ash subtracted from that of the total insoluble residue. 

Injurious Metals.—These may be derived either from the vessels in which the products are prepared or stored or from mineral colours added to some extent they may be detected in the ash. For a more complete investigation, especially of metals which may be eliminated during the incineration as volatile compounds, use is made of one of the known methods for the destruction of organic substances, e.g., treatment with hydrochloric acid and potassium chlorate, the residue being examined by the ordinary methods of qualitative analysis. 

Ash.—5 grams of the substance, weighed in a platinum dish, are carefully charred over a small flame and then incinerated in a muffle at a dull red heat. If any large amount of ash is left, it should be examined for added mineral matter and injurious metals. 

The aqueous solution thus obtained is filtered and 200 c.c. (corresponding with 4 grams of the leather) evaporated on a water-bath and the residue dried at ioo° this represents total soluble matter or loss on washing. The dried residue is then incinerated, the ash representing the soluble mineral matter or soluble ash (which may be examined qualitatively) the difference gives the soluble organic matter. 

Ash.—The dry residue from the determination of the water is incinerated and the ash weighed. If this exceeds 1%, adulteration with mineral matter is probable, this being confirmed by qualitative analysis of the ash. Such analysis is useful in any case to detect the presence of heavy metals (especially iron), which may be introduced during the manufacturing processes and are harmful in the dyeing. The ash of alizarin consists normally of sodium or calcium salts. 

Determination and Examination of the Ash.—The residue from the preceding determination is incinerated. A large amount of ash may indicate addition of extraneous mineral substances, the nature of which may be determined by qualitative analysis of the ash. 

Mineral Matters.—5 grams of the substance are incinerated and the ash weighed. If this is large in amount, addition of inorganic matter may be suspected and the ash qualitatively analysed.

The emission inventory of dioxin-like compounds in South Korea was determined during two preliminary studies (KMOE, 2001, 2002a). For emission factors, the preliminary study (KMOE, 2001) adopted measured values for waste incinerators and the values of UNEP chemicals Toolkit (UNEP Chemicals, 2001) for the other sources. Estimated PCDDs/DFs emission in 1999 ranged from 1163 to 1595 g I-TEQ yr-1 due to uncertainties in emission factors and activities (Table 2.6). Besides the preliminary estimate, since the late 1990s extensive measurements of PCDDs/ DFs have been performed at waste incinerators and the emission data by 2004 had been compiled for 1800 incinerators. Moreover, nationwide industrial sources have been investigated every year since 2001 34 fer-rous/non-ferrous metal production factories in 2001, 114 non-ferrous metal and mineral production factories in 2002, 73 chemical/energy/ landfill factories and crematories in 2003, and 63 municipal wastewater treatment plants and 9 types of vehicles in 2004. By 2005, measurements of total dioxin emissions had been made on 288 industrial sources. Based on these measurements, KMOE made the first official estimate of PCDDs/DFs emission in South Korea. It has been estimated that the total PCDDs/DFs emission was 1021 g I-TEQ yr-1 in 2001 (KMOE website) (Table 2.6). This emission was approximately 62% of that... 

A major contributor of PCDDs/DFs release to environments is waste incinerators (77-89% in preliminary study and 86% in follow-up studies) followed by 6-19% from ferrous/non-ferrous metal industry and <5% from others including power generation and heating, mineral production, chemical industry, and non-point sources. Non-point sources like transportation and uncontrolled burning processes showed a minimal contribution of <2%.
