“…By assessing the performance of chemical processes in an unambiguous manner, these tools could help both in retrofitting the design and operation of existing processes to make them more environmentally conscious and developing new technologies that are inherently sustainable, as evidenced by different applications. ,, Therefore, to better understand how these tools have been applied in decision making during sustainable chemical process design, a comprehensive review on sustainability assessment methods associated with chemical processes is of great necessity. Similar studies − exist, but they usually have a much narrower focus. For example, Abbaszadeh and Hassim review studies where methods had been applied to evaluate environmental impacts within the petrochemical industry.…”

Integrating sustainability principles as a design goal in chemical engineering has become a major challenge facing modern society. This review aims to provide a comprehensive investigation regarding available methods that can potentially be used by industries to quantify the sustainability performance of chemical processes. First, the expansion in the definition of sustainable processes is summarized, forcing corresponding methods to broaden the assessment scope. Then, 30 methods are classified into three categories based on their scope to facilitate their analysis: material and energy flow analysis, life cycle assessment, and sustainability assessment. Key attributes of methods in each category are extracted and discussed in detail. In addition, illustrative examples have been introduced to demonstrate the applicability of these methods. Finally, challenges of the present methods and future research directions for sustainability assessment methods are also highlighted, such that the objective of efficient, environmentally friendly, and economic processes can be realized.

THE CONCEPTUAL DESIGN FOR LIQUID EFFLUENT TREATMENT OF UO2 KERNEL FABRICATION. The pebble fuel for HTGR is prepared through fabrication of UO2 kernel, coated particle and spherical element fuel. In the fabrication of UO2 kernel by external gelation method, a multicomponent of liquid effluent is generated. Therefore, the liquid effluent is required to be treated for safety reason before disposed to waste storage. In this paper, the conceptual design for the liquid effluent treatment of UO2 kernel fabrication is performed with the simulation process using CHEMCAD software. CHEMCAD is a software that can be utilized for chemical process design. The results showed that the proposed conceptual design is able to separate valuable components: isopropyl alcohol (IPA) and tetrahydrofurfuryl alcohol (THFA). The flowrate of IPA product is 5.28 kg/h with purity of 0.99 in mass fraction and the flowrate of THFA product is 1.01 kg/h with purity of 0.99 in mass fraction.Keywords: liquid effluent, UO2 kernel, CHEMCAD, HTGR.

“…At first, the design problem is open to interpretation, and information is scarce; therefore, the metrics for the sustainability dimensions cannot be easily implemented. In later design stages, when detailed information is available, the potential for sustainability improvement is limited by preliminary decisions made on process design . Therefore, process intensification is a tool that allows the development of new apparatus and techniques that, compared to those commonly used today, are expected to bring drastic improvements in manufacturing and processing, substantially reducing the size/capacity ratio of production, energy consumption, or waste production, and ultimately, produce cheaper and more sustainable technologies…”

Acetone purification is one of the most critical stages of its production process, because a large amount of energy is required. Due to this high energy consumption, the process turns out to be not very sustainable and not friendly to the environment. In this sense, the development of intensified alternatives that minimize energy consumption in this process is of utmost importance. Besides, the safest possible processes are sought, so it is necessary that the control properties of these novel processes be studied at an early design stage. This work proposes two new intensified systems for the purification of acetone; the intensified schemes are a thermally coupled distillation system with a side rectifier and a Petlyuk arrangement. The results indicate that in this type of systems where interconnection flows are used, the magnitudes of these flows have a direct impact on energy consumption, because lower values of interconnection flows as in the case of the thermally coupled system achieve a reduction, whereas higher values as in the case of the Petlyuk system have a negative impact. As for the control properties, the intensified schemes present better values of the condition number with respect to the conventional design, because the interconnection flows reduce the disturbance of the manipulable variables. On the other hand, if the feed is disturbed, the interconnection flows generate an increase in the disturbance in the system, obtaining that the conventional system presents the best values. Therefore, making a balance between the studied designs and looking for a system that presents the best sustainability indicators, the thermally coupled system obtains the best results with a 25.92% energy saving and CO2 emission reduction with respect to the conventional system and acceptable values for the control and safety indexes.
