Special Issue Information

Dear Colleagues,

The study of process systems engineering (PSE) aims to provide a series of effective and efficient solutions for promoting better sustainability with the simultaneous consideration of economic, environmental, and social impacts. The interdisciplinary and multiscale features of PSE imply that a good integration of conventional unit operation and advanced techniques, including artificial intelligence, multiobjective optimization, life-cycle assessment, multicriteria decision-making analysis, and supply chain optimization, can be achieved to promote a systematic solution for sustainable processes design, optimization, synthesis, and selection. The involved processes vary significant and include fossil fuel utilization, biomass valorization, waste heat recovery, renewable energy systems and carbon capture and utilization, etc. Overcoming sustainability challenges in these processes, such as improving energy efficiency and reducing carbon emissions, can be solved through PSE study with the above-mentioned techniques, boosting sustainable development.

This Special Issue, “Process Systems Engineering for Better Sustainability: Challenges and Perspectives”, aims to cover recent advances in the development of sustainable processes and present solutions for improving sustainability. Topics include, but are not limited to, the following areas:

  • Process design, integration, intensification, and synthesis;
  • Advanced process/supply chain optimization methods;
  • Sustainability criteria and decision-making analysis;
  • Life-cycle assessment of process systems;
  • Waste valorization and waste heat recovery;
  • Applications of AI techniques in the PSE;
  • Techno-economic and energy/exergy analysis.

Separating heavy components from natural gas not only enhances safety, improves pipeline transportation, ensures product quality, and addresses environmental considerations, but it also exerts an influence on global energy trends. Therefore, separating heavy components is necessary and can result in beneficial goods. This article presents a comprehensive study on the process simulation and optimization of the recovery of natural gas condensate via the combined refrigeration of a mixture of ethane and propane as a refrigerant. The optimization objectives include maximizing the recovery of ethane and propane, minimizing energy consumption, and achieving desired product quality targets. A sensitivity analysis was performed to assess the impact of key parameters on process performance. Using Aspen HYSYS software, the influence of the cooler outlet stream temperature and expander outlet stream pressure on the shaft power and profit of a dry gas compressor was analyzed based on the operating conditions of the case plant, which has a processing capacity of 2988 kmol/h. The profitability of the plant is at a maximum when the cooler’s outlet stream temperature is −61 °C and the expander’s outlet stream pressure is 2500 kPa. After optimization, the refrigeration cycle system can reduce the plant’s energy consumption by 1516.4 kW. An optimized process design can lead to enhanced recovery efficiency, reduced energy consumption, and improved profitability in the natural gas industry. Full article
