Chlorine 00 ON 6. The samples collected should be protected from loss of moisture, as well as contamination.

Technical Manual for the Analysis of Fuels

Not given Method developed for f1145. See Reference fl for other points. Frequently, a large portion of a single sample, deemed to be representative of the materials being analyzed, will be thoroughly homogenized and split into two or more samples submitted to the laboratories involved. The amount of acid neutralized is determined by titration with sodium hydrox- ide.

Applicable to any petro- leum oil.

Applicable to relatively non-volatile petroleum products which oartially decompose on distillation at atmospheric pressure.

While no exact correlation exists between the Conradson D and Ramsbottom D methods for carbon residue, an approximate correlation for petroleum products has been found and is shown graphically in Reference 1.

The original reference should be checked if precision is critical, since the wording may imply special conditions for the applicability of the precision numbers given. Either isothermal or adia- batic calorimeter jackets may be used. Sul- fate ion is determined by titra- tion with barium perchlorate or by precipitation of barium sul- fate followed by trubidometry. It is often desired to have the net calorific value which is the value corresponding to combustion at atmospheric pressure, under conditions such that all water in the products remains in the form of vapor.


In cases where more than one method may be suitable, the pre- ferred method is listed first. Table VII-2 gives a summary listing of the fuel analyses that are important for peat combustion, along with an identification of the preferred method of analysis and other information relating to the analyses.

Method specified by ASTM for testing of meth- anol. Corrections must be applied for- heats of formation of H2S04 and HN The main emphasis is on methods of anal- ysis; sampling methods are, in general, only discussed briefly. Most methods were developed for petroleum and petroleum products. Their principal weakness may be that test sample sizes may be too small for RDSF that is not sufficiently homo- geneous resulting in erratic results on replicate samples.

Coke samples are dried in the laboratory only if the samples are wet. The two exceptions to proximate and ultimate analyses are chlorine content and the coal heating value which are important in evaluating the properties of a sample. Column packing and length modified as necessary for particular mixture. Shale Fuel Oil D. Calorific Value ASTM D Sample is burned in closed system and sulfur oxides are absorbed as sulfate into sodium carbonate solution.


For petroleum crude and fuel oils: Applicable to crude petro- leum oil and volatile non- viscous petroleum gases. The time in seconds it takes a fixed volume of sample to flow through a capillary Is measured.

May be applicable to MF if sulfur is primar- ily connected with volatile compounds. Preprints Volume 20, No. The recovery of the added elements or compounds is indicative of the accur- acy being achieved.

These methods determine the gross calorific value which is obtained under conditions of constant volume. Sieve Analysis NA The number given for repeatability is the acceptable difference for duplicate results by the same laboratory; that for reproducibility is the acceptable difference for duplicate results submitted by two or more laboratories.

Of all the possible variables which affect the characteristics of shale oil, the method of production is, by far, the most significant. Repeatability r Coal 2Z S – 0. Somewhat different amounts may be required for methyl fuel. Method specified by ASTM for v1145 of methanol.
