ASTM E3183-24(Guide)
Standard Guide for Harvesting Coal Combustion Products Stored in Active and Inactive Storage Areas for Beneficial Use

SIGNIFICANCE AND USE
4.1 Purpose—This guide provides a process for reclamation of existing CCPs placed in active and inactive storage areas. The guide includes information on the following activities required for the safe and effective reclamation of CCPs from storage areas: (1) Background Review of CCP Storage Areas; (2) Detailed Characterization of CCP Storage Areas; (3) Harvesting Planning and Scoping of CCP Storage Areas; (4) Harvesting Detailed Design and Approval of CCP Storage Areas; and (5) Harvesting Implementation of CCP Storage Areas. More detailed descriptions of these activities are in Sections 6 through 10.  
4.2 Potential Beneficial Uses of CCPs—There are many CCP storage areas that are potentially harvestable and can provide a functional benefit in a wide variety of beneficial uses. The beneficial use of CCPs contained in these storage areas can have significant environmental and economic benefits for the facility, the facility owner and the local economy, and can significantly reduce disposal operations (1-4).4 Beneficial use of CCPs can provide industry with a safe and responsible way to economically manage the CCPs, while promoting conservation and recycling/reuse, meeting sustainability goals, and addressing the shortage of CCPs in some building product market areas (1, 2, 5). CCPs consist of fly ash, bottom ash, boiler slag, fluidized-bed combustion (FBC) ash, economizer ash, and flue gas desulfurization (FGD) material (see Terminology E2201 for definitions of CCPs) (6, 7).  
4.2.1 Fly ash is the most abundant CCP in existing storage areas. Its beneficial uses include, but are not limited to: partial replacement for cement in concrete and concrete products – once in concrete, fly ash reacts with Portland cement to create additional reaction products that improve the strength and durability of concrete; raw feed for the production clinker – fly ash can be calcined along with other minerals to produce clinker; blended cements – fly ash can be an important component ...
SCOPE
1.1 This guide covers a framework to address critical aspects related to the harvesting of CCPs placed in active (operational) and inactive (closed or no longer receiving CCPs) storage areas. These storage areas may be used for wet or dry material, and may be located at active or inactive facilities (that is, coal-fired electric utilities or independent power producers that are currently generating electricity or have ceased to do so, respectively). Also, CCPs may be harvested from active or inactive storage areas located on-site or off-site of the facility.  
1.2 This guide does not include information on how to determine what storage areas or facilities, or both, should be selected for potential harvesting of CCPs, as each entity may approach a harvesting program in accordance with their own harvesting pursuits and regulatory requirements. In addition, it does not include information on how an energy company or other interested parties should evaluate inventories to determine the order of their storage areas for potential harvesting, including consideration of risk, performance, and cost. This guide is intended to be used to evaluate the potential harvesting of the storage areas once the storage areas are selected for evaluation.  
1.3 This guide is comprised of the following sections: Scope, Section 1; Referenced Documents, Section 2; Terminology, Section 3; Significance and Use, Section 4; Project Planning and Scoping, Section 5: Background Review of CCP Storage Areas, Section 6; Detailed Characterization of CCP Storage Areas, Section 7; Harvesting Planning and Scoping of CCP Storage Areas, Section 8; Harvesting Detailed Design and Approval (as applicable) of CCP Storage Areas, Section 9; and Harvesting Implementation of CCP Storage Areas, Section 10. Not all information within this guide will be necessary for each harvesting project, and the user should determine the applicability of each section.

ASTM D3466-06(2023)(Test Method)
Standard Test Method for Ignition Temperature of Granular Activated Carbon

SIGNIFICANCE AND USE
5.1 Activated carbons used in gas-phase adsorption may be subjected to heating, either from heat applied externally to the carbon bed, or heat generated by radioactive4 contaminants, or by the adsorption process itself. If the application of heat is sudden, or if no ample means to conduct the heat from the carbon bed exists, the carbon bed may ignite. This test method provides a controlled laboratory test to determine the temperatures at which such ignition occurs. As stated in 1.2, this does not necessarily give the temperature at which ignition will occur under a specific bed operating condition. This test method does, however, allow some ranking of carbons with regard to ignition temperature, and is a useful quality control method for unused carbons.
SCOPE
1.1 This test method covers the determination of reference ignition temperature of granular activated carbon in flowing air. This test method provides a basis for comparing the ignition characteristics of different carbons, or the change in ignition characteristics of the same carbon after a period of service.  
1.2 The ignition temperature, as determined by this test method, cannot be interpreted as the probable ignition temperature of the same carbon under the operating conditions of a specific application unless those conditions are essentially the same as those in this test method.2 If it is desired to determine the ignition temperature of the carbon under a specific set of operating conditions, the test may be modified to simulate such conditions, taking into consideration the following variables: (1) air flow rate; (2) moisture content of the carbon; (3) bed depth; (4) relative humidity of the air stream; (5) heating rate; (6) contaminants (for example, hydrocarbons, etc.) in the air stream; and (7) contaminants that may have been adsorbed by the carbon under prior service conditions.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Calculating Coal and Coke Analyses from As-Determined to Different Bases

SIGNIFICANCE AND USE
4.1 The calculations of analytical data for the coal and coke test parameters listed in Section 6, assume the analysis sample has been prepared according to Practice D2013 and Test Method D3302.  
4.2 This practice provides formulas, to enable calculations of data from the as-determined analysis sample to various moisture bases, in common use by the coal and coke industry.  
4.3 This practice provides guidance to enable calculations of weight-average data from various lots or sublots, which, initially, are provided at different moisture bases.  
4.4 The principles given in this practice are applicable to the calculation of cumulative data (e.g., for trade purposes or for sieve analyses or washability analyses).
SCOPE
1.1 This practice lists formulas that allow analytical data to be expressed in various bases in common use. Such bases are: as received, dry, equilibrium moisture, dry ash free, and others.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3838-23(Test Method)
Standard Test Method for pH of Activated Carbon

SIGNIFICANCE AND USE
4.1 When a fluid containing an adsorbate is passed through a bed of activated carbon, chemical reactions may take place between the activated carbon, its other noncarbonaceous constituents, and the adsorbate-containing fluid. The pH of the carbon may be a significant parameter of such a reaction and therefore may be an important characteristic of the carbon.
SCOPE
1.1 This test method covers determination of the pH of a water extract of activated carbon.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 6.

ASTM E953-23(Test Method)
Standard Test Method for Fusibility of Refuse-Derived Fuel (RDF) Ash

SIGNIFICANCE AND USE
4.1 This standard is for determining the fusibility of ash produced from RDF.  
4.2 Limitations of Ash Fusibility Data—Ash fusibility data are often over-interpreted. In practice, types of burning equipment, rate of burning, temperature and thickness of fire bed or ball, distribution of ash forming mineral matter in the RDF, and viscosity of the molten ash may influence ash behavior more than the ash fusibility characteristics determined by the laboratory test. Also, conditions existing during applied combustion of RDF are so complex that they are impossible to duplicate completely in a small-scale laboratory test. Therefore, the analysis should be considered an empirical one and the data only qualitative.
SCOPE
1.1 This test method covers the observation of the temperatures at which triangular pyramids (cones) prepared from RDF ash attain and pass through certain stages of fusing and flow when heated at a specific rate in controlled, mildly reducing, and oxidizing atmospheres.  
1.2 The test method is empirical, and strict observance of the requirements and conditions is necessary to obtain reproducible temperatures and enable different laboratories to obtain comparable results.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5003/D5003M-23(Test Method)
Standard Test Method for Hardgrove Grindability Index (HGI) of Petroleum Coke

SIGNIFICANCE AND USE
5.1 The HGI is used to predict the ranking of raw petroleum cokes or calcined petroleum cokes in industrial size mills used for crushing operations. The rankings are based on energy required and feed rate or both.  
5.2 The HGI is also used to select raw petroleum cokes and coals that are compatible with each other when milled together in a blend so that segregation of the blend does not occur during particle size reduction.
SCOPE
1.1 This test method covers the determination of the hardgrove grindability index (HGI) of those petroleum cokes that contain no dedusting additive. The procedure for this test method is the same as in Test Method D409. Sections of this test method contain the significance and use of the HGI of petroleum coke, preliminary sample preparation procedures, and procedure and precision and bias data specific to petroleum coke.  
Note 1: The size consistency (particle size distribution) of fluid petroleum coke is generally 100 % passing a 6.7 mm [0.265 in.] sieve and greater than 80 % passing a 2 mm [No. 10] sieve. Much of fluid cokes will pass a 600 μm [No. 30] sieve. Because of this fineness the HGI value is related to the coarser particles in fluid coke and large samples are required to prepare sufficient material of the correct particle size for Test Method D409.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.2.1 Exception—Hardgrove grindability index is unitless.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determination of Bulk Density for Specific Size Fractions of Calcined Petroleum Coke Using a Transaxial Pressure Pycnometer

SIGNIFICANCE AND USE
5.1 The bulk density is an indicator of calcined petroleum coke porosity and packing capability which is an important coke property for anode production in aluminum industry. This procedure will allow an automated measurement of specific sized fractions ranging from 8 mm to 0.25 mm coke particles.  
5.2 Results from this test method are used in determining coke specifications, classification purposes, and for quality control.
SCOPE
1.1 The test method covers the determination of bulk density for a specific size fraction of calcined petroleum coke using an automated pycnometer that compacts coke by applying transaxial pressure under a controlled force.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D4292-23(Test Method)
Standard Test Method for Determination of Vibrated Bulk Density of Calcined Petroleum Coke

SIGNIFICANCE AND USE
5.1 Vibrated bulk density, VBD, is an indicator of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon applications. (Warning—Vibrated bulk density for a sample of calcined petroleum coke is strongly dependent upon average particle size and particle size range. Bulk density tends to increase with decreasing coke size. A narrow particle size range for this test minimizes the possibility for variation due to skewing of the test sample toward either screen defining the sample. Particle size range tested should be agreed upon by the purchaser and supplier.)  
Note 1: An example of the use of VBD to characterize coke for prebaked anodes for aluminum smelting is reported by Belitskus3 who found particles passing through a 0.59 mm opening, No. 30, sieve and retained on a 0.30 mm opening, No. 50, sieve to be preferred. Other popular ranges are particles passing through a 2.36 mm opening, No. 8, sieve and retained on a 1.17 mm opening, No. 16, sieve for the continuous Soderberg anode process and particles passing through a 6.68 mm opening sieve (equivalent to a 0.265 in. USA Series) and retained on a 3.33 mm opening, No. 6, sieve for graphite electrode manufacture.
SCOPE
1.1 This test method covers the determination of bulk density of a representative 2 kg sample of calcined petroleum coke, after vibration to increase compaction.  
1.2 The procedure is limited to particles passing through a 6.68 mm opening sieve (equivalent to a 0.265 in. USA Series) and retained on a 0.21 mm opening sieve (equivalent to a 70 mesh USA Series). Further, the procedure is limited to a specific test sample having particles retained between screens having openings that differ by a factor of less than  and preferably less than 2.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
