Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONIntroduction of petroleum coke into the coal market in recent years has necessitated the use of manyof the test methods for

3、coal so like data would be available for comparison and blending purposes.TestMethod D409 does not cover petroleum coke in its scope and its statements of precision and bias donot include petroleum coke. This test method provides the procedures and precision and bias data forthe hardgrove grindabili

4、ty index (HGI) of petroleum coke. Use of this test method or Test MethodD409 produces the same value for the sample of petroleum coke being analyzed.1. Scope*1.1 This test method covers the determination of the hardgrove grindability index (HGI) of those petroleum cokes that containno dedusting addi

5、tive. The procedure for this test method is the same as in Test Method D409. Sections of this test method containthe significance and use of the HGI of petroleum coke, preliminary sample preparation procedures, and procedure and precisionand bias data specific to petroleum coke.NOTE 1The size consis

6、tency (particle size distribution) of fluid petroleum coke is generally 100 % passing a 6.73 mm (No. 3) sieve and greater than80 % passing a 2.00 mm (No. 10) sieve. Much of fluid cokes will pass a 0.59 mm (No. 30) sieve. Because of this fineness the HGI value is related tothe coarser particles in fl

16、 PO Box C700, West Conshohocken, PA 19428-2959. United States13.1.3 Hardgrove Grindability Index, HGI, unitless, nin petroleum coke technology, measurement of the relative ease ofpulverizing a raw petroleum coke or green petroleum coke in comparison with coal standards. The higher the HGI value, the

17、 easierthe petroleum coke is to grind.3.1.4 petroleum coke, nsolid, carbonaceous residue produced by thermal decomposition of heavy petroleum fractions orcracked stocks, or both.3.1.5 raw petroleum coke, npetroleum coke that has not been calcined.4. Summary of Test Method4.1 The sample of petroleum

18、coke is reduced (crushed) to produce a high yield of particles passing a 1.19 mm (No. 16) sieveand retained on a 0.59 mm (No. 30) sieve. These particles are reduced in the hardgrove grindability machine according to TestMethod D409. The quantity of particles retained on a 0.074 mm (No. 200) sieve is

19、 used to calculate the HGI of the sample.5. Significance and Use5.1 The HGI is used to predict the ranking of raw petroleum cokes or calcined petroleum cokes in industrial size mills used forcrushing operations. The rankings are based on energy required and feed rate or both.5.2 The HGI is also used

20、 to select raw petroleum cokes and coals that are compatible with each other when milled together ina blend so that segregation of the blend does not occur during particle size reduction.6. Hazards6.1 Calcined petroleum coke is generally coated with a dedusting agent to decrease the occurrence and t

21、he quantity of dustduring subsequent transporting of the calcined petroleum coke. The dedusting agent is an oil or suitable material. When a dedustingagent is present and is not removed prior to the determination of HGI there can be interference in the sieving step to measure theportions retained on

22、 and passing a 0.074 mm (No. 200) sieve. Removal of the dedusting agent after calcined petroleum coke isreduced to pass the 4.76 mm (No. 4) sieve and before stage crushing to pass the 1.19 mm (No. 16) sieve is required. Suitablesolvents for oil removal are dichloromethane, dichloroethane and toluene

23、. (WarningSee the appropriate materials safety datasheet.) The solvent used must be removed prior to the reduction to pass the 1.19 mm (No. 16) sieve. Heating to 10 C above theboiling point of the solvent used or application of vacuum is satisfactory for the removal.7. Sampling and Sample Preparatio

24、n7.1 Aguide for sampling petroleum cokes and calcined coke3 and a practice for preparing samples of petroleum coke are in theASTM process of development and will be referenced when they are available. The sample preparation in Test Method D409 isadequate.7.2 When a dedusting agent is present remove

25、it in the manner required by the supplier of the calcined petroleum coke. Thesupplier knows what the added agent is, and should best know how to remove it. See Test Method D4930.8.
