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

17、o Trade (TBT) Committee.14. 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 machine according toTest Meth
18、od D409. 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 operations. The rankings ar
19、e 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 Calcined petroleum coke is ge
20、nerally 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 thedetermination of HGI there can be
21、interference in the sievingstep to measure the portions retained on and passing a0.074 mm (No. 200) sieve. Removal of the dedusting agentafter calcined 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 solvent
22、s for oil removal aredichloromethane, dichloroethane and toluene. (WarningSeethe appropriate materials safety data sheet.) The solvent usedmust be removed prior to the reduction to pass the 1.19 mm(No. 16) sieve. Heating to 10 C above the boiling point of thesolvent used or application of vacuum is

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 sample preparation in TestMethod D
24、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 D4930.8. Procedure8.1 The procedure (including apparatus) for raw pet
25、roleumcoke and for calcined petroleum coke having no dedustingagent is the same as listed in Test Method D409.9. 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 p
