Comprehensive Review of Process Simulation to Industrial Applications and Sustainability Integration

Puspita Nurlilasari — Thu, 14 Aug 2025 00:00:00 +0700

Aspen HYSYS has become a foundational tool in process engineering, offering robust capabilities for modeling, simulating, and optimizing complex industrial processes. This review explores the application of Aspen HYSYS across diverse industries—including energy generation, petrochemicals, renewable fuels, and waste heat recovery—with a specific focus on heat and mass balance calculations. Through several validated case studies, we illustrate how HYSYS enables engineers to evaluate thermal efficiency, optimize mass flows, and reduce environmental impacts. The study includes detailed performance data for shell-and-tube heat exchangers, reactive distillation systems, organic Rankine cycles, and dehydration processes. Each simulation case is contextualized in terms of energy conservation and sustainable process design, demonstrating direct contributions to the United Nations Sustainable Development Goals (SDGs), especially SDG 7 (Affordable and Clean Energy), SDG 9 (Industry, Innovation and Infrastructure), and SDG 13 (Climate Action). Moreover, the review elaborates on numerical techniques and thermodynamic models used in HYSYS, offering guidance on choosing appropriate property packages and convergence settings. Challenges in fouling, turndown operation, and reference-state discrepancies in enthalpy tracking are also discussed. Ultimately, this article underscores the potential of process simulation not only as a tool for design and analysis but also as a driver of innovation and sustainability in industrial operations.

Sustainable Development Goals Through Carbon Dioxide Conversion to Formic Acid as Coagulation Agent

Puspita Nurlilasari, Nikolas Ardian Prihantoro — Thu, 14 Aug 2025 00:00:00 +0700

Addressing global sustainability challenges requires innovative approaches that integrate environmental, economic, and technological solutions. This article explores the sustainable development potential of converting carbon dioxide (CO₂), a major greenhouse gas, into formic acid—a valuable chemical compound used as a freezing agent in the coagulation of natural rubber. The study further delves into the solid-state characteristics of materials involved in this process, emphasizing the distinction between crystalline and amorphous solids. Understanding the atomic arrangement in materials contributes to optimizing coagulation and freezing techniques critical for natural rubber production. This work links CO₂ valorization with advanced material science principles, promoting circular economy and environmental sustainability aligned with the United Nations Sustainable Development Goals (SDGs).

Transforming Corn Stalks into Sustainable Block Boards for Durable Children's Toys: A Material Science Perspective Linked to Sustainable Development Goals

Puspita Nurlilasari, Nurvirzy Muflih Attallah, Andry Masri — Thu, 14 Aug 2025 00:00:00 +0700

This paper presents a comprehensive study on the transformation of corn stalks, an abundant agricultural waste, into structurally reliable block boards with high bending strength suitable for children’s toys. The innovation leverages physical principles of matter states, fiber mechanics, and sustainable design thinking inspired by Andry Masri’s creative-industrial research. The resulting material meets key performance indicators in bending, elasticity, water resistance, and cost competitiveness. Furthermore, this study frames the material’s development and application within the United Nations Sustainable Development Goals .SDGs., particularly SDG 3, 9, 12, 13, and 15.

Heat and Mass Balances in Liquid Soap Production for Sustainable Industrial Development Aligned with SDGs

Puspita Nurlilasari, Tiara Maylafaizah Br Bangun, Maelani Sri Agustine — Thu, 14 Aug 2025 00:00:00 +0700

This study presents a comprehensive analysis of mass and energy balances in the liquid soap manufacturing process with the objective of enhancing process efficiency and promoting cleaner production principles in alignment with the United Nations Sustainable Development Goals (SDGs), particularly SDG 9 (Industry, Innovation and Infrastructure), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action). Leveraging data compiled from over 60 international journal publications and validated through process simulation software (Aspen Plus®), the research systematically quantifies the flow of materials and energy within each stage of the production process. The investigation identifies critical inefficiencies such as excessive energy consumption in drying and waste sludge generation. Through scenario analyses including feedstock substitution with waste cooking oil and heat integration techniques, the study demonstrates potential reductions in raw material costs by up to 18%, energy consumption by 10%, and greenhouse gas emissions by approximately 28%. These findings underscore the significant role of integrated mass and energy management strategies in steering traditional manufacturing towards sustainable, economically viable, and environmentally responsible operations.
