Con- densed solvent and water are continuously separated In a trap, the water settling in the graduated section of the trap and measured volumetri- cally.
Should be applicable for petroleum liquids, except LPG. There are, however, a large number of ASTM methods available for various fuels, including two or more alternative methods for many parameters, and the choice of the most applicable method is important.
Cruci- ble with sample is kept cover- ed to keep air out. ASTM D 2. The lowest temperature at which movement of the oil is observed is the pour point. Procedures adequate for the preparation of a laboratory sample of RDSF are given in several sources.
The samples collected should be protected from loss of moisture, as well v1145 contamination. General Recommendations 2 3. P Varies with the initial boil- ing point and end point of the material and with the rate of change of thermometer readings.

Applicable to most types of petroleum oils, including crude, residual fuels, dis- tillates, and lubricating oils containing no addi- tives. Potassium lodate is added as the combustion proceeds and the amount of standard iodate consumed is a measure of the sulfur content of the sample. Liquid Fuels 98 C. The use of nitrogen in place of air prevents oxidation of the sample. Work in progress at Arthur D. Limit of method is 20 mg. Frequently, the composition is described in terms of solubility in various solvents, such as hexane, pentane, pyridine, and benzene.
The manual covers gaseous fuels, liquid petroleum fuels, waste lubricating oil, shale oil, coal liquids, methyl fuel, coal, coke, refuse -derived solid fuels, and peat. The chlor- rine compounds liberated are absorbed in a sodium carbonate solution and the amount of chlorine present determined gravlmetrically by precipita- tation as silver chloride.
Differences in technique may occur as the result of the coke’s physical form or chemical composition and are noted. Table IV-1 gives a summary listing of the fuel analyses that are important for shale oil and coal liquids combustion, along with an identification of the preferred method of analysis and other information relating to the analyses.
Manufacturer’s data sheets for methanol. See Reference 11 for details. Sul- fur contents are generally lower than in petroleum oils.

Syste- matic observations of temper- ature and condensate volume are made, and the reported results calculated from their data.
These are the sample requirements for a single analysis. Ingitlon of coke may require additional time. When working with peat that is not sufficiently homogeneous, the sample sizes for these analyses should be increased, if possible.

There is some question regarding the stability of such samples in sam- pling containers. Thus, these reference materials are suitable for validating both the absolute accuracy and the precision of analytical methods. Gaseous Fuels Virtually all gaseous reference xstm are prepared by blending pure com- ponents, both by weight and by volume, rather than analyzing a “real” sam- ple. Refuse-Derived Solid Fuels 77 B.
Private communication with Mr. A listing of the sources is given in Table A-l. An appropraite hydrometer is lowered into the sample and allowed to settle.
Io- dine and bromine, if pre- sent, will add to chlorine result. Only vola- tile hydrocarbons are mea- sured. Mass spectrometry affords qualitative identification of major components. In some cases, the product fuels may be hot and may still contain some amounts of sulfur compounds, higher hydro- carbons, and ammonia which have not been removed.
