A joint economic evaluation and FP2O techno-economic resilience approach for evaluation of suspension PVC production

The production of polyvinyl chloride (PVC) involves obtaining a thermoplastic polymer from vinyl chloride monomer (VCM) and ethylene, primarily through the suspension method. This process is vital for manufacturing various products, such as pipes and coatings. However, its high-energy consumption necessitates economic evaluations to assess feasibility. In this work, a dual approach is proposed: a Feedstock-Processing-Product-Operation (FP 2 O) based techno-economic resilience analysis via sensitivity analysis alongside economic evaluation. The study evaluated a PVC production process with a capacity of 518,400 t/y of VCM over a 15-year plant lifespan. The techno-economic assessment revealed a Total Capital Investment of $609, 882, 203, a Payback Period of 4.22 years, and a Return on Investment of 14.38 %. Positive Net Present Value and a cost/benefit ratio >1 indicate the plant's installation under proposed conditions is favorable. Additionally, the technical-economic resilience analysis identified the process's response to changes in PVC price, raw material costs, and production capacity, guiding improvement actions pre- and post-plant assembly. • Explores the production of polyvinyl chloride (PVC) from vinyl chloride monomer (VCM) and ethylene using the suspension method. • Utilizes a Feedstock-Processing-Product-Operation (FP 2 O) based techno-economic resilience analysis along with traditional economic evaluation. • Positive Net Present Value and a cost/benefit ratio greater than 1 suggest favorable conditions for plant installation. • Identifies the process's response to changes in PVC price, raw material costs, and production capacity, providing guidance for improvement actions. • Combines economic evaluation with techno-economic resilience analysis for a robust assessment of suspension PVC production.
