ABSTRACT
petroleum coke, coal export quality
Quality of petroleum cokes and coals has been evaluated for export specificationsrequired 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 n anode grade, green (raw) coke used i calcination, petroleum coke for high- and low-Btu fuel grade, low- and 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.
INTRODUCTION
The A. J. Edmoud Co. has over 30 years extensive experience specialized in analysis, testing and evaluation of petroleum cokes and coals for export specifications, which are used primarily as solid fuels in power plants and cement kitus and in other applications to produce specialty products, carbon anodes, metallurgical cokes, etc Process development services currently provided include consulting,training, and process studies in production of calcined petroleum cokes for aluminum anode-grade. Quality ofpetroleum cokes was evaluated by Rolle, et. aL [ 1,2], investigating the effects of metal impurities (vanadium, nickel and sodium) on the properties of cokes and anodes.
The quality ofpetroleum cokes produced by U. S. refineries bas been affected by several major governing
