AGC Vinythai commenced commercial operations following a major capacity expansion at its chlor-alkali plant in Map Ta Phut, Thailand. The project marks one of the largest global deployments of e-BiTAC v7 technology from thyssenkrupp nucera, reinforcing the company’s commitment to safe, efficient, and energy-optimized chlor-alkali electrolysis within its integrated vinyl production chain.
Advanced e-BiTAC v7 Electrolyzer Drives Capacity Growth
At the heart of the expansion is the newly installed e-BiTAC v7 bipolar ion exchange membrane electrolyzer, which delivers an annual production capacity of 220,000 tons of caustic soda. In addition, the chlorine generated at the expanded chlor-alkali facility will directly supply AGC Vinythai’s vinyl plants. As a result, the company has increased its PVC production capacity from 3,00,000 tons to 7,00,000 tons per year—more than doubling output. Importantly, this project represents the largest investment in AGC Vinythai’s history, further consolidating its position as Thailand’s leading supplier of caustic soda and PVC.
Meeting Rising Demand in Southeast Asia
With this expansion, AGC Vinythai is strategically positioned to address the rapidly growing demand for caustic soda and PVC across Southeast Asia. The region continues to witness strong industrial growth, particularly in:
*Construction and infrastructure
*Packaging
*Automotive manufacturing
*Pulp and paper
*Textiles
Since these sectors rely heavily on chlor-alkali derivatives, the increased capacity ensures a stable and competitive supply chain across regional markets.
Energy Efficiency and Process Optimization
Keisho Cho, CEO of thyssenkrupp nucera Japan, emphasized, “Our decades of experience in filter press technology ensure even pressure distribution across the membrane, enabling more stable and efficient chlor-alkali electrolysis”. He further noted that the system optimizes energy consumption while reducing membrane stress—two critical factors in improving operational efficiency and lowering lifecycle costs.
Expanded Project Scope and Engineering Integration
Initially commissioned in 2025 to supply the e-BiTAC v7 electrolyzer, thyssenkrupp nucera’s role later expanded. The project scope now includes:
*Basic engineering services
*Balance-of-plant systems
*Additional unit systems beyond the core electrolyzer
This integrated approach ensured seamless execution and operational readiness of the expanded chlor-alkali plant.
Strengthening Leadership in the Chlor-Alkali Sector
As per the press release, overall, the expansion strengthens AGC Vinythai’s footprint in the chlor-alkali and vinyl value chain. By combining advanced electrolysis technology with significant capacity enhancement, the company not only improves operational efficiency but also secures long-term growth in Southeast Asia’s dynamic chemicals market.
