Quality Control
PetroChina Fushun Petrochemical Company implements full‑lifecycle quality control covering raw‑material incoming inspection, on‑line process monitoring and finished‑product testing. Strict sampling and analysis are performed for crude oil and auxiliary feedstock before entering production units. Real‑time process parameters are tracked across refining, wax‑processing and polyolefin workshops. Every batch of Kunlun‑branded paraffin, polyolefin and synthetic rubber undergoes standardized lab tests to verify melting point, mechanical indexes and impurity content. Core wax products have obtained FDA and REACH compliance certifications, satisfying strict quality requirements for export to global markets.
Three-Stage Quality System
Incoming Inspection
Every raw material batch tested against specifications before entering production. Certificate of Analysis verified for all suppliers.
In-Process Monitoring
Real-time process parameter monitoring with DCS systems. Automated sampling and testing at critical control points throughout production.
Final Release
Comprehensive end-product testing against international standards. Batch release only after all specifications are confirmed and documented.
Testing Methods & Standards
Chromatographic Analysis
HPLC and GC-MS analysis for purity, impurity profiling, and molecular identification per USP and EP standards.
Wet Chemistry
Classical titration, gravimetric, and colorimetric methods for assay determination and limit testing.
Physical Testing
Comprehensive physical property measurement including viscosity, density, refractive index, and particle size distribution.
Stability Studies
Long-term and accelerated stability testing per ICH guidelines ensuring product quality throughout shelf life.
Quality Without Compromise
PetroChina Fushun Petrochemical Company establishes standardized quality management systems linked with HSE operation rules to sustain stable product quality. The company regularly calibrates testing instruments, optimizes inspection standards and carries out quality‑oriented staff training. For specialty products such as microcrystalline wax, cold‑chain packaging wax and bottle‑cap‑grade resins, customized testing specifications are applied. Abnormal feedback from domestic and overseas customers is traced and analyzed promptly. Through continuous process optimization and quality‑risk prevention, the enterprise maintains high qualification rate of finished goods and delivers consistent‑specification petrochemical materials for worldwide industrial clients.
