The results of microscopy by the Ono method are considered an important part of the data base in a computerized multivariate analysis conducted routinely for cement quality control in plants of the Onoda Cement Company in Japan (Aizawa, 1985). Microscopical data are said to be helpful in making frequent adjustments in kiln parameters, clinker silo operation, and adjustment of cement fineness. The continually updated analysis involves the following process variables burning zone temperature, kiln outlet clinker temperature, secondary air temperature, extraction air temperature, kiln rotation torque, nitrous oxide, percent clinker passing the 5-mm screen, and liter weight. In some Japanese cement plants, clinkers are recycled until the microscopical targets have been met, according to Uchikawa (1992). 

High liter weight High alite content(Brown, 1948) increased time of burning at high temperature (Hawkins, 1979)... 

Low liter weight MgO slightly high, CaO distinctly high aggregated clinkers (Brown, 1948)... 

The produced chnker is polymineralic in nature, and contains—in addition to calcium sulfoaluminate— limited amoimts of dicalcium silicate, anhydrite, and free lime. 8ulfospurrite may also occasionally be present (Herrick et al., 1992 8u et al., 1992). The chemical composition of the sidfoaliuninate phase may vary over a limited range, with a partial substitution of Ca by Mg ", and Al by 8i", Fe, or Ti" (8u et al., 1992). The clinker has a high porosity, with a liter weight of 650-850 g/L, and is easy to grind. 

Figure 5.9 shows an example of the efficiency of these products. The reductions of CFPP and pour point can easily attain 6 to 12°C for concentrations between 200 and 600 ppm by weight. The treatment cost is relatively low, on the order of a few hundredths of a Franc per liter of diesel fuel. In practice, a diesel fuel containing a flow improver is recognized by the large difference (more than 10°C) between the cloud point and the CFPP. 

The desired improvements are usually on the order of 3 to 5 points, beginning with a base of 45-48. Under these conditions between 300 and 1000 ppm by weight of additive must be used. The treating costs are acceptable, being on the order of a centime (hundredth of a French Franc) per liter.

Fig. 10 shows the curves for the canister weight and the amount of vapor removed for the example canister during a purge event. In this case, the canister is being purged with an air stream flowing at a rate of about 22.6 liters per minute for a total of 15 minutes. The curves show that the n-butane desorption rate is initially quite rapid, and then it levels out at a lower rate. 

PPM is the abbreviation for parts per million. A part per million is equal to a milligrams per liter. Parts per million refers to a ratio of weights. For example, one part per million is one pound in a million pounds, one ounce in a million ounces, one gram in a million grams, etc. 

We wish to separate titanium dioxide particles from a water suspension. The method chosen is centrifugation. The unit is a continuous solid-bowl type with a bowl diamter of 400 mm, a length to width ratio of 3.0, and the unit operates at 2,000 rpm. The feed contains 18 % (weight basis) solids and is fed to the unit at 2,500 Liters/hr at a temperature of 95° F. The average particle size is 65 /tm. (a) Determine the amount of solids recovered per hour (b) Determine the solids concentration in the centrate (c) Determine the horsepower requirments for the centrifuge (d) Size a graviy settler to remove an additional 15 % of the solids. 

Mg/L Milligrams per liter = ppm (parts per million) - expresses a measure of the concentration by weight of a substance per unit volume. 

Hydroxypregna-5,16-dien-20-one Acetate Oxime 3j5-Hydroxy-pregna-5,16-dien-20-one acetate (30 g) is dissolved in 300 ml of anhydrous pyridine and 6.75 g of hydroxylamine hydrochloride is added. The mixture is stirred until solution is achieved, left in a tightly closed container at room temperature for 4 days and then poured into 1.5 liters of water. The flask is rinsed with water and the combined separated crystals are collected on a Buchner funnel, washed with water and dried to constant weight in an oven at 100°. Yield 30 g (96.5% of theory) mp 220-223°.
