Thallium is likewise recovered from flue dusts emitted during sulfide roasting for H2SO4 manufacture, and from the smelting of Zn/Pb ores. Extraction procedures are complicated because of the need to recover Cd at the same time. There are no major commercial uses for T1 metal world production in 1983 was estimated to be 5-15 tonnes p.a. and the price ranged from 60 to 80 per kg depending on purity and amount purchased. 

In 1994, purchase prices for ICE units ranged from 40,450 for Model VC2 to 98,880 for Model V4. Rental prices of VC2 and V3 units were estimated to be 220 per month and for the V4 systems were estimated to be 374 per month. According to an Air Force evaluation of the technology, renting units would be more practical for any application lasting less than 10 months (D179377, p. 4-2). 

The Oil Snapper soil remediator is available by the 2-ft (56-liter) bag or may be purchased in bulk on 15-, 25-, or 50-bag pallets. Prices per bag and per pallet are lower when purchasing in bulk. Prices range from 18.00 per bag when purchasing 20 or more 50-bag pallets to 25 per bag when purchased individually. 

Hardware costs are among the more deceptive points in pricing a package, or budgeting for a project. Computers can be purchased at any price range, from 50 to 500,000 and up with the range extending from micro to mini and maxi. Hie concern is not the cost of the hardware but what can you do with it That... 

Unless otherwise indicated, the unit price is 1000, K. Except where indicated, notably for fired heaters, refrigeration systems, and cooling towers (which are installed prices), the prices are purchase prices, FOB, with delivery charges extra. In the United States delivery charges are of the order of 5% of the purchase price, but, of course, dependent on the unit value, as cost per lb or per cuft. Multipliers have been developed whereby the installed cost of various kinds of equipment may be found. Such multipliers range from 1.2 to 3.0, but details are shown in Table 21.3. 

Powdered activated carbons offer the advantage of low cost compared to granules in terms of both purchase price and capital expenditure (investment in adsorber units, pumps, etc). The cost of PAC is about 1.00/kg versus 2/kg for GAC [19]. For a system treating 4 million/day the cost is about 0.03/1,000 L [67], A wider range of impurity removal levels can be attained with powdered carbon, where the dose of carbon per batch can be adjusted, depending on the type and concentration of the contaminants [68]. GAC is normally used in continuous flow deep beds and is advantageous when variations in adsorption condi-...
