Technical Manual for the Analysis of Fuels

Acidity due to HC1 is deducted. The matrix also contains sub- stantial amounts of entrapped, uncondensed alkanes, and fatty acids. The relatively small number of compounds possible in gaseous fuels has re- sulted in the development of methods for the identification and measure- ment of individual major and minor components using either gas chromato- graphy or mass spectrometry. A modification is given for light distllate oils; the method, as given above, is used on a 10Z distillation residue of the sample.

Specific references to methods listed are given in Table VI Modifications are pre- scribed for high residue mate- rials.

An air-dried sample is sepa- rated into four designated fractions by means of an 8- mesh and a mesh sieve. Generally applicable to crude petroleum and petro- leum products normally handled as liquids and having a Reid vapor pres- sure of 1.

Environmental assessments of processes using peat will heed to include additional fuel d115 beyond those covered in this manual. Those substances which are most accurately characterized, either by pre- paration or by analysis, are generally termed “certified” reference mate- rials.

The seven series are: Sul- fur contents are generally lower than in petroleum oils. Applicable to RDFS, in- cluding samples with high nitrate contents. In addition, many standard methods, including some ASTM methods, leave certain options to the parties con- cerned – e. Modifications are prescribed for high residue materials. Test temperature should be speci- fied by parties concerned.

Modifications are given for different types of petroleum products; in some cases, the parties concerned must specify the temperature and time ast the test. If the method normally used with the instrument is applicable for the fuel in question, then it may be desirable to use that instrumental method since it may result in time and cost savings. C02, Cj-Cg hydrocarbons uses partition column of sill- cone oil or other absor- bants.

Most methods were developed for petroleum and petroleum products. The liberated compounds in the gaseous state are collected, condensed, and upgraded into a liquid pro- duct that is the rough equivalent of a crude oil.

Cruci- ble with sample is kept cover- ed to keep air out. Tests showed standard deviations on replicate samples to range from 0. While detailed development plans have been prepared for major shale oil production facilities, no shale oil is being commercially produced at this time mid A ml sample is distilled under prescribed conditions which depend on the vapor pressure and initial and final distillation points.

The astk of these measurements is, for the most part, a func- tion of the accuracy with which the calibration standards have d115 made. For petroleum crude and d11445 oils: Applicable to crude petro- leum oil and volatile non- viscous petroleum gases. See article on “Coal,” Volume 5, page Differences which may occur in sample size and astk paration are described in Section 3, dealing with actual methods.

Should be applicable for less homogeneous samples of D1415 where larger sam- ples must be used. For organic compounds in general expect: Use of smaller columns with different liquid substrates b. Not applicable if water content is less than 0. While it is expected that the listed methods will be wstm applicable to methyl fuel, this has yet to be proven by labora- tory tests.

Test tem- perature must be specified by the parties concerned. Too frequently, analyses of samples – including fuels – result in inaccurate or meaningless results because an inappro- priate method was used. But, again, the choice seems reasonable. Significant discrepancies can be seen in the results for peat and, to a qstm lesser extent, for the processed municipal refuse. The method is more time consuming than the bomb washing method.

When the content of higher alcohols is large, the methanol content may be roughly estimated by subtracting the percentages of higher alcohols plus water from Not known All notes appear on the last page of this table. Both methods asfm clude variations for sampling from a wide variety of containers for a wide variety of sample types, as shown by the examples below. Determined by difference from proximate analysis.

Method developed for solid fuels and should be appli- cable to RDSF. ast

Preprints Volume 20, No. The infor- mation given is basically a description and discussion of established methods of sampling analysis for a variety of hydrocarbon fuels.

Additional informa- tion on the methods of analyses, including alternate methods for some parameters, is given in Section 3 of this chapter. Unpublished data from December,through June, The gloves should be made of butyl rubber, rather than neoprene or any other material, since they have been found to have the slowest permeation rate for a similar material, coal tar creosote7.

To carry out this procedure, the follow- ing general steps1 should be followed: Because shale oil and coal liquids may contain carcinogens, laboratory coats and gloves should be work whenever there is the chance of spillage.

Possible uses for the methyl fuel include: The non-standard methods will include, for example, those that are state-of-the-art or that use rapid instrumental techniques.

An alternate approach uses boric acid in place of Semi-micro Kjeldahl:
