A warning is given that nitrogen, when present in excess of 0. Not applicable to LPG. It is not d1145 intent of this chapter to cover methods appli- cable to raw unprocessed municipal refuse. Coal Liquids 35 2. No zstm was made – in the preparation of this manual – to review all available methods because of limitations on time and funds. Oxygen is determined indirectly by subtracting from the per- centages of hydrogen, carbon, sulfur, nitrogen, and ash. Should be applicable for low boiling or distilate SO and CL.

Generally applicable to liquid petroleum products. Should be appli- cable for SO and CL. RDSF ast, be used as the sole fuel in a heat-generating process, or it may be used aastm a supplementary fuel.

Petroleum fuels may be subjected to long periods of storage, and additives e. The use of nitrogen in place of air prevents oxidation of the sample. Column packing and length modified as necessary for particular mixture. Nitrogen in shale oil naphtha fraction is present as pyridines, pyrroles, and nitriles. Applicable to crude pet- roleum oil and volatile non-viscous petroleum pro- ducts, except liquid petro- leum gases.

Refuse-Derived Solid Fuels 75 B. The ash of the coal, as well as part of the sulfur, is contained in the carbonaceous residue, coke.

Quantities of the sample required, costs, and standard reference materials where available are given in Table III Limit of method is 20 mg. The peat container specified the contents to be “pure” Canadian Sphagnum Peat Moss. The Directory is revised every two years. 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.

A polished copper strip in im- mersed in a sample at a certain temperature for a time charac- teristic of the sample being tested. It should be noted that none of the listed methods were developed for specific applicability xstm shale oil and coal liquids.

The ASTM Annual Book of Standards 5 astn many alternative analyses for some of the parameters listed; our choice has been made from those which appeared to offer the widest applicability. Intended as guidelines in the planning of a sampling operation, they include: Maximum Specified Value ML: Applicable to any petro- leum oil. Shale Fuel Oil D.

The outer cardboard peat container was received by laboratory 2 in a damaged condition, though the inner plastic bag con- taining the sample was not broken. The parameters added will be those yielding information on the chemical nature of the fuel e. Corrections must be applied for- heats of formation of H2S04 and HN This standard describes the various types of sampling procedures asstm sampling containers to be used for different liquid petroleum fuels.

A riffle – which is a sample divider – is then used to reduce the sample to about 50 g. Results are usually re- ported on an “as received” basis or on a “dry” basis. When working with peat that is not sufficiently homogeneous, the sample sizes for these analyses should be increased, if possible.

RDSF taken here to be a processed municipal refuse in its as-fired form may lack any real homogeneity,and its composition may vary on both a daily and seasonal basis. The homogeneity of the sample may not be comparable, and even if it was, the values given in Table VII-3 may not apply where the absolute values of the parameter being measured in RDSF are significantly different from those in coal and coke.

Additionally, larger sample sizes would be preferable for the determination of the cal- orific value of RDSF because their values are roughly half of those of the more common fuels e.

Analysis is by either the Kjeldahl-Gunning or an alter- native method. Additional information on the methods of analysis, including alternate methods for most parameters is given in Section 3 of this chapter.

An instrumental method in which the sample is decomposed ‘at high temperatures in the absence of air and with the aid of oxidiz- ing agents. Not known All notes appear on the last page of this table. Final approval by ASTM may require additional time. Classification by rank, according to ASTM Ddivides coal into four major classes with regard to rank or age – anthracitic, bituminous, sub- bituminous, and lignitic.

The Department of Commerce or its equi- valent in most states publishes directories of research organizations and laboratories within the State. It is pos- sible that unanticipated problems will require some methods modifications. Although coke may vary greatly in physical form and chemical composition, a standard set of analyses is applicable to most samples. Test temperature must be speci- fied by the parties concerned.
