| Abstract Scope |
Rain Carbon operates a central laboratory in the US to monitor GPC and CPC quality for six coke calcining plants. With a wide range of different coke qualities, it is critical to provide reliable results to control production and report accurate results to customers. The objective of this paper is to summarize Rain Carbon’s Quality Management System and Quality Control Programs to ensure consistent, high quality results. The Quality Control (QC) program monitors the performance of instrumentation for key analyses. Reference standards and/or control samples are analyzed at a designated frequency. To supplement this, the laboratory added a Quality Assurance (QA) program to monitor total measurement variability including sample preparation and analyst variability. Periodic Gage R&R studies are undertaken to develop precision limits for each test. As a final step, the company organizes global CPC Round Robins which give additional data and provide a valuable service to the industry. |
