The application of integrated sustainability tool for production of cyclohexanone

Abstract

The sustainability problem for reactor systems which is consists of simultaneous calculation of the three sustainability index (one-dimensional index, two-dimensional index, three-dimensional index) in one single analysis and is shown in Figure 1. 1D sustainability analysis is developed according to Shadiya and High (2012), in which a one by one index is calculated for all three indicators. The environmental indicator is divided into two different indexes, which are environmental metric and resource usage metric. Economic indicator is evaluated by using a set of metrics for the cost effectiveness. Whereas, the social indicator is measured by using total inherent safety index and also health risk. Then, for 2D sustainability analysis is developed by referring to Ulhman and Sailing (2010), in which a 2D sustainability indicator is introduced by simultaneous assessment of two criteria out of three. The categories involved are economicenvironmental, socioeconomic and socio-environmental which are expressed in term of mass, water and energy intensity index. Furthermore, 3D sustainability analysis is based on Martins et. al. (2007). Here, the indexes used are energy intensity, material intensity, potential chemical risk and potential environmental impact. In this case, those four indexes are located inside a 3D index that complies all aspects in sustainability.
