GC triumphs at the Asian Technology Excellence Awards 2025

Advanced PDH Optimization Modeling drives higher yields, energy savings, and lower CO₂ emissions.

PTT Global Chemical Public Company Limited (GC) has been honoured with the prestigious Thailand Technology Excellence Award for Digital - Chemicals at the Asian Technology Excellence Awards 2025. The recognition highlights GC’s Advanced PDH Optimization Modeling—a homegrown digital solution that makes propane dehydrogenation (PDH) operations faster, safer, and more sustainable.

What the Advanced PDH Optimization Modeling does

PDH converts propane to propylene, a core feedstock for many products. Traditionally, operators adjusted reactor conditions by trial-and-error, guided by licensor input and experience. These adjustments often took days to validate and risked lower yields, energy loss, or even unplanned shutdowns from coke formation.

GC’s Advanced PDH Optimization Modeling transforms this process by innovating new methodology to combine reaction-kinetics expertise with advanced analytics for predicting optimal reactor settings and forecasting coking trends. The result is faster, more precise adjustment, greater operational stability, and standardised, data-driven practices.

The initiative has led to a measurable annualised impact, including a reduction of 1,200 tonnes in hydrogen consumption through improved propylene yield. Additionally, energy consumption has decreased by 5,200 barrels, and carbon dioxide emissions have been reduced by 1,700 tonnes.

These improvements not only boost competitiveness but also advance GC’s decarbonisation journey.

Proudly built within GC

Developed entirely in-house, with intellectual property filed across five countries, the Advanced PDH Optimization Modeling showcases GC’s world-class talent and commitment to innovation. The solution has elevated daily operations from intuition-based to data-driven excellence, setting new standards across the GC Group.
