1、Designation: D 5003 06aAn American National StandardStandard Test Method forHardgrove Grindability Index (HGI) of Petroleum Coke1This standard is issued under the fixed designation D 5003; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi

2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 man

3、yof the test methods for coal so like data would be available for comparison and blending purposes. TestMethod D 409 does not cover petroleum coke in its scope and its statements of precision and bias donot include petroleum coke.

4、forthe hardgrove grindability index (HGI) of petroleum coke. Use of this test method or Test MethodD 409 produces the same value for the sample of petroleum coke being analyzed.1. Scope*1.1 This test method covers the determination of the hard-grove grindability index (HGI) of those petroleum cokes

Much of fluid cokeswill pass a 0.59 mm (No. 30) sieve. Because of this fineness the HGI valueis related to th

15、00, West Conshohocken, PA 19428-2959, United States.4. Summary of Test Method4.1 The sample of petroleum coke is reduced (crushed) toproduce a high yield of particles passing a 1.19 mm (No. 16)sieve and retained on a 0.59 mm (No. 30) sieve. These particlesare reduced in the hardgrove grindability ma

16、chine according toTest Method D 409. The quantity of particles retained on a0.074 mm (No. 200) sieve is used to calculate the HGI of thesample.5. Significance and Use5.1 The HGI is used to predict the ranking of raw petroleumcokes or calcined petroleum cokes in industrial size mills usedfor crushing

17、 operations. The rankings are based on energyrequired and feed rate or both.5.2 The HGI is also used to select raw petroleum cokes andcoals that are compatible with each other when milled togetherin a blend so that segregation of the blend does not occurduring particle size reduction.6. Hazards6.1 C

18、alcined petroleum coke is generally coated with adedusting agent to decrease the occurrence and the quantity ofdust during subsequent transporting of the calcined petroleumcoke. The dedusting agent is an oil or suitable material. Whena dedusting agent is present and is not removed prior to thedeterm

19、ination of HGI there can be interference in the sievingstep to measure the portions retained on and passing a 0.074mm (No. 200) sieve. Removal of the dedusting agent aftercalcined petroleum coke is reduced to pass the 4.76 mm (No.4) sieve and before stage crushing to pass the 1.19 mm (No. 16)sieve i

20、s required. Suitable solvents for oil removal are dichlo-romethane, dichloroethane and toluene. (WarningSee theappropriate materials safety data sheet.) The solvent used mustbe removed prior to the reduction to pass the 1.19 mm (No. 16)sieve. Heating to 10C above the boiling point of the solventused

21、 or application of vacuum is satisfactory for the removal.7. Sampling and Sample Preparation7.1 A guide for sampling petroleum cokes and calcinedcoke3and a practice for preparing samples of petroleum cokeare in the ASTM process of development and will be refer-enced when they are available. The samp

22、le preparation in TestMethod D 409 is adequate.7.2 When a dedusting agent is present remove it in themanner required by the supplier of the calcined petroleumcoke. The supplier knows what the added agent is, and shouldbest know how to remove it. See Test Method D 4930.8. Procedure8.1 The procedure (

23、including apparatus) for raw petroleumcoke and for calcined petroleum coke having no dedustingagent is the same as listed in Test Method D 409.9. Precision and Bias9.1 PrecisionThe statements for repeatability and repro-ducibility for petroleum coke and calcined petroleum coke arebeing developed fol

24、lowing RR:D02-1007.49.2 BiasThe procedure in this test method has no biasbecause the value of the hardgrove grindability index can bedefined only in terms of the test method.10.
