PVC is widely used in packaging, electrical insulation, and medical devices due to its versatility owing to its resistance, incombustible and barrier properties as well as affordable cost. In the present study, bibliometric and co-occurrence analyses are proposed to identify trends, gaps, future directions, and challenges regarding process system engineering (PSE) applied to the production process of PVC using VOSviewer as a tool for analyzing the data obtained from SCOPUS. A mapping of different topics alluding to simulation of PVC production was provided to gain a better insight into the development of the topic and its progression. The findings indicate that the literature on this topic falls into five different clusters: modeling and simulation of PVC production, process control and optimization, and optimization strategies of the process. From a co-occurrence study we identified that mathematics and statistics applied to polymer chemistry, separation phenomena, and polymer production are the main areas of interest for further research. The trends suggest that Monte Carlo and numerical simulation can contribute to a deeper understanding of PVC’s properties and behavior. In addition, the focus on plastics and microplastics reflects concerns about the environmental impact. A bibliometric study evidenced that PSE provides the tools for improvement in PVC production processes by employing advanced process engineering techniques. Modelling and new algorithms for simulation methods of continuous polymerization processes are important to enhance accuracy and efficiency across various applications. The study also proposes a research agenda for future researchers working in the field of the use of PSE applied to the PVC production process.

This study focuses on the energy-efficient separation process of styrene monomer, avoiding the formation of an azeotrope by using a vacuum distillation, derived from the pyrolysis of waste polystyrene (PS). The direct-indirect sequence, which positions the separation column of ethylbenzene and styrene monomer as the last step, exhibited a 30% reduction in the total utility consumption and a 37% reduction in the total annual cost compared to that of the direct-direct sequence that separates lighter components sequentially. A dividing wall column (DWC) configuration derived from the direct-indirect sequence showed the most significant reduction of 40% in utility consumption. However, when the feed capacity was low, the increased capital cost of DWC resulted in a total annual cost similar to that of the direct-indirect sequence. As the capacity of the entire distillation system increased, the reduction in the total operating cost of the DWC was amplified, indicating the advantages of using the DWC in high product throughputs from both energy and economic perspectives. Therefore, implementing the DWC in large-scale PS recycling processes demonstrates superior performance compared to the conventional distillation process, resulting in a more streamlined process with substantial energy savings and CO2 emissions.
