Case Study: China National Bluestar (Group) Co., Ltd. achieves real-time visibility and production and energy optimization with OSIsoft PI System

Optimizing Chemical Processes with the PI System

China National Bluestar (Group) Co., Ltd., a manufacturer of chemical materials and animal nutritional additives with 12 plants across nine provinces, needed to boost production and energy efficiency but lacked real‑time visibility. Headquarters relied on manual tank checks and delayed inventory calculations, which slowed reporting, hampered supply‑chain and operational decisions, and made it difficult—and sometimes risky—to test process optimizations.

Bluestar deployed the OSIsoft PI System (PI-to-PI interface, PI Asset Framework and PI SQC) to centralize and automate data collection, run soft‑sensing models and simulate control changes. The system provided real‑time visibility, cut report generation time by 90%, enabled optimization of more than 30 production units, improved quality and decision‑making, and delivered concrete savings such as $200,000/year in steam costs at one site.
