Analysis of Petroleum Cokes and Coals for Export Specifications Required in Use

Quality of petroleum cokes and coals has been evaluated for export specifications required in use of specialty products and utility bels. Various green and calcined cokes, produced at refineries m California, and coals for shipment are sampled at California and national ports, and analyzed by using ASTM Methods. Quality analysis reports include: proximate and ultimate analyses, metals, tu, density, size distribution, hardgrove grindability, and other physical, chemical and mechanical properties. Some of recent analysis results liom calcined petroleum coke produced for aluminum anode grade, green (raw) coke used in calcination, petroleum coke for highand low-Btu fuel grade, lowand high-rank coals are compared and presented. QC/QA/SQC programs have been utilized for good precision and accuracy of data generated with acceptable repeatability and reproducibility.
