Backed by Decades of Coal, Coke, Fuel, and Combustion Analysis Experience

Independent Petroleum Coke Testing and Analysis Services

Clark Testing provides comprehensive petroleum coke testing services to support refiners, calcined coke producers, commodity traders, bulk terminals, cement manufacturers, power producers, and industrial fuel users throughout North America. Our laboratory delivers accurate, independent analytical data that helps customers verify product quality, maximize commercial value, optimize combustion performance, and support environmental compliance requirements.

Petroleum coke (pet coke) is a critical byproduct of refinery delayed coking operations and serves as an important fuel and carbon source for numerous industrial applications. Because petroleum coke quality can vary significantly based on crude source and refining processes, routine laboratory testing is essential to ensure product consistency, contract compliance, and operational performance.

Clark Testing's experienced analytical team performs petroleum coke laboratory testing in accordance with recognized ASTM methodologies, providing reliable data for quality assurance, product certification, fuel evaluation, process optimization, and commercial transactions.
