Abstract: In this paper, we assess 13 process technologies to improve energy efficiency in the Chlor-Alkali sector of Shandong province in China up to 2025 using a techno-economic approach. The results show energy efficiency improvement (EEI) potentials of 9% in the caustic soda and 38% in the polyvinyl chloride (PVC) production process compared to a frozen-efficiency development. The most influential technologies are energy-efficient electrolysis technology in brine electrolysis step and heat recovery technology in Vinyl Chloride Monomer synthesis (VCM) step. The energy savings can be translated into mitigated CO 2 emissions of 10 Mt in 2025. The larger part of this potential is found to be cost-effective from a firm's perspective. In conclusion, significant saving potentials are still available. However, to achieve the all potentials, additional energy policies are needed.
