- Conversion to membrane technology completed by June 2009
- Chlorine capacity increased from 390,000 to 430,000 metric tonnes per year
- Sites involved: Gendorf and Knapsack
- Improved supply of PVC raw materials and caustic soda
Project Completion
The conversion of chlor-alkali electrolysis plants at Gendorf and Knapsack to energy-saving and environmentally friendly membrane technology was completed by the end of June 2009. This upgrade ensures that all chlorine production for Vinnolit's German PVC sites now uses modern technology.
Increased Capacity
With this investment, chlorine capacity has increased from 390,000 to 430,000 metric tonnes per year. This enhancement improves the raw material supply for connected PVC production and optimizes the delivery of the co-product caustic soda.
Balanced Production
According to Managing Director Dr. Ralph Ottlinger, the Gendorf site now has a chlorine capacity of 180,000 tonnes, while Knapsack has 250,000 tonnes. This results in two large, state-of-the-art monomer sites with balanced capacities across all production stages.
Sustainability and Efficiency
The conversion to membrane technology aligns with the European chlorine industry's voluntary commitment to sustainable development. It also contributes to increased energy efficiency and reduced CO2 emissions, helping to mitigate the impact of rising energy prices.
