ASTM D4930-23

Standard Test Method for Dust Control Material on Calcined Petroleum Coke

SIGNIFICANCE AND USE
5.1 The test is designed to quantify the amount of dust control material added to calcined coke. The dust control material is applied to calcined coke to help maintain a dust-free environment. It generally serves no other useful purpose. It adds mass to the coke and can have a negative effect on the quality of carbon and graphite artifacts made from the treated coke. For these reasons the coke customer wants to know the amount of dust control material on the coke and can specify a maximum level.
SCOPE
1.1 This test method covers the determination of the amount of material applied to calcined coke to control dust associated with coke handling and transportation.  
1.2 This test method is limited to those materials that are soluble in a solvent that can be used in a Soxhlet extraction type of apparatus such as methylene chloride (dichloro-methane).  
Note 1: Methylene chloride is the most popular solvent for removing dust control oil at the time this procedure is being written. Toluene and methyl chloroform, however, have been used with equal results on all cokes tested which have included only those sprayed with aromatic or waxy materials.  
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. For specific warning statements, see 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.

Overview

ASTM D4930-23: Standard Test Method for Dust Control Material on Calcined Petroleum Coke provides a precise methodology for determining the quantity of dust control material applied to calcined petroleum coke. Developed by ASTM International, this standard supports industries reliant on the quality and cleanliness of calcined coke, such as aluminum, steel, and carbon product manufacturing. Dust-suppressant materials, like oils or waxes, are typically added during handling and transport to reduce airborne particulate emissions. Quantifying these additives is essential since excess dust control material can negatively affect the quality of subsequent carbon or graphite products.

Key Topics

• Dust Control on Calcined Petroleum Coke: The test measures the amount of de-dusting material, which is primarily used to minimize dust, ensuring safer workplace conditions and cleaner transportation.
• Applicable Materials: The method is limited to dust control substances soluble in solvents suitable for Soxhlet extraction, particularly methylene chloride, but also toluene or methyl chloroform for aromatic or waxy coatings.
• Laboratory Procedure:
  • Extraction using a Soxhlet apparatus dissolves the dust control material from a representative, dried sample of calcined coke.
  • Solvent is evaporated, and the residue is measured to determine the mass percentage of dust control additives.
• Accuracy and Repeatability: The standard specifies clear guidelines for repeatability and reproducibility, ensuring confidence in results among laboratories and buyers.
• Safety Considerations: All steps demand adherence to health, safety, and environmental protocols, especially regarding the handling of volatile and toxic solvents like methylene chloride and acetone.

Applications

The ASTM D4930-23 test method is critical for:

• Petroleum Coke Producers: Ensuring that the dust suppression applied meets customer and regulatory limits, maintaining product quality.
• Carbon and Graphite Product Manufacturers: Verifying that raw material specifications regarding dust suppressants are met, as excess material can harm artifact properties.
• Quality Control Laboratories: Auditing shipments for compliance and supporting material acceptance or rejection decisions.
• Shipping and Handling: Validating that calcined coke meets hygiene and emission requirements during transport, crucial for environmental compliance.

By following this standard, industry players can:

• Maintain consistent product quality
• Meet customer and regulatory requirements
• Minimize environmental and occupational hazards associated with coke dust

Related Standards

Several ASTM and industry standards complement or reference ASTM D4930-23 to ensure comprehensive coke sampling, preparation, and analysis:

• ASTM D346 - Practice for Collection and Preparation of Coke Samples for Laboratory Analysis
• ASTM D2013 - Practice for Preparing Coal Samples for Analysis
• ASTM D2234/D2234M - Practice for Collection of a Gross Sample of Coal
• ASTM D4057 - Practice for Manual Sampling of Petroleum and Petroleum Products
• ASTM D4175 - Terminology Relating to Petroleum Products, Liquid Fuels, and Lubricants
• ASTM E11 - Specification for Woven Wire Test Sieve Cloth and Test Sieves

Keywords: calcined petroleum coke, dust control material, de-dusting, Soxhlet extraction, ASTM D4930-23, petroleum coke analysis, quality control, carbon production

By adhering to ASTM D4930-23, organizations demonstrate a commitment to product quality, regulatory compliance, and safe industrial practices in calcined petroleum coke handling and applications.

4.1 The dust control material is dissolved from a weighed dry representative sample of 6.3 mm maximum sized coke by methylene
chloride in a Soxhlet extraction apparatus. The mass of the residue remaining after distilling and evaporating the solvent is the mass
of dust control material. The amount of residue as a percent of the original mass is calculated.
