Environmental analysis of gasoline blending components through their life cycle
Teresa Margarida Correia de Poço Mata; Raymond L. Smith; Douglas M. Young; Carlos Albino Veiga da CostaThe contributions of three major gasoline blending components (reformate, alkylate and cracked gasoline) to potential environmental impacts (PEI) are assessed. This study estimates losses of the gasoline blending components due to evaporation and leaks through their life cycle, from petroleum refining to vehicle refuelling. A sensitivity analysis is performed using different weighting factors for each potential...
Evaluating the environmental friendliness, economics and energy efficiency of c...
Teresa Margarida Correia de Poço Mata; Raymond Smith; Douglas Young; Carlos Albino Veiga da CostaThe design and improvement of chemical processes can be very challenging. The earlier energy conservation, process economics and environmental aspects are incorporated into the process development, the easier and less expensive it is to alter the process design. In this work different process design alternatives with increasing levels of energy integration are considered in combination with evaluations of the p...
Life cycle assessment of different reuse percentages for glass beer bottles
Teresa Margarida Correia de Poço Mata; Carlos Albino Veiga da CostaLife cycle assessment (LCA) is increasingly becoming an important tool for ecological evaluation of products or processes. In this study the environmental impacts associated with the returnable and the non-returnable glass beer bottles were assessed in order to compare different reuse percentages. The inventory analysis is performed with data obtained from two Portuguese companies (a glass bottles producer and ...
