1、Designation: D5003 06a (Reapproved 2011)Standard Test Method forHardgrove Grindability Index (HGI) of Petroleum Coke1This standard is issued under the fixed designation D5003; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea
2、r of last revision. A number in parentheses indicates the year of last reapproval. 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 m
3、ethods for 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 hardgrov
4、e grindability 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. Scope1.1 This test method covers the determination of the hard-grove grindability index (HGI) of those petroleum cokes thatcontain no de
5、dusting additive. The procedure for this testmethod is the same as in Test Method D409. Sections of thistest method contain the significance and use of the HGI ofpetroleum coke, preliminary sample preparation procedures,and procedure and precision and bias data specific to petroleumcoke.NOTE 1The si
6、ze consistency (particle size distribution) of fluidpetroleum coke is generally 100 % passing a 6.73 mm (No. 3) sieve andgreater than 80 % passing a 2.00 mm (No. 10) sieve. Much of fluid cokeswill pass a 0.59 mm (No. 30) sieve. Because of this fineness the HGI valueis related to the coarser particle
7、s in fluid coke and large samples arerequired to prepare sufficient material of the correct particle size for TestMethod D409.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.2.1 ExceptionHardgrove grindability index is uni

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Refere

Summary of Test Method4.1 The sample of petroleum coke i
15、s 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 machine according toTest Method D409. The quantity of particles retained on a0.074 mm (No. 200) sieve is used to
16、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 operations. The rankings are based on energyrequired and feed rate or both.5.2 The HGI is also used to select r
17、aw 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 Calcined petroleum coke is generally coated with adedusting agent to decrease the occurrence and the quantity ofd
18、ust 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 thedetermination of HGI there can be interference in the sievingstep to measure the portions retained on and passing a 0.
19、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 is required. Suitable solvents for oil removal are dichlo-romethane, dichloroethane and toluene. (WarningSee thea
20、ppropriate 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 or application of vacuum is satisfactory for the removal.7. Sampling and Sample Preparation7.1 A guide for samp
21、ling 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 sample preparation in TestMethod D409 is adequate.7.2 When a dedusting agent is present remove it in themanner requi
22、red 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 D4930.8. Procedure8.1 The procedure (including apparatus) for raw petroleumcoke and for calcined petroleum coke having no dedustingagent is the same as

Precision and Bias9.1 PrecisionThe statements for repeatability and repro-ducibility for petroleum coke and calcined petroleum coke arebeing developed following RR:D02-1007.49.2 BiasThe procedure in this test method has no biasbecause the value of the hardgrove grindab
