A novel perspective to bitumen refineries life cycle assessment and processes emissions

This study provides an introduction and a novel view of the impacts of oil refineries industry on human health, ecosystem quality and resources. The scope and issues for dealing with these challenges are rather wide and complex because the Oil refineries are complex facilities. Several processes, such as distillation, vacuum distillation, or steam reforming are required to produce a large variety of oil products such as gasoline, light fuel oil or bitumen. The goals, perspectives and expectation for the environmental practice and control have changed dramatically over the last couple of decades. Hence the required approach has to be multidisciplinary, based on established scientific concepts and sound engineering principles. The environmental impacts of oil refineries are assessed using the technique of life cycle assessment (LCA). In this paper, only the material production phase of the bitumen LCA is considered. To improve the quality of the LCA, a regionalized life cycle inventory (LCI) database for the Oil refineries and commercial LCI databases are used to validate and model unit processes with an LCA software.
