Abstract
In the present study, to minimize water consumption and reduce wastewater production in an oil refinery, a technique called water pinch analysis (WPA) was used with two single and double pollutant approaches. Total dissolved solids (TDS) and chemical oxygen demand (COD) were selected as the index pollutants. The results showed that the use of WPA has reduced the overall consumption of freshwater in the refinery on average between 79 m3/h (45%) in the single pollutant approach (77 m3/h for COD and 81 m3/h for TDS) and 99 m3/h (56%) in the double pollutant approach. It was also found that the volume of produced oily and sanitary effluents decreased between 31 and 52 m3/h. These findings show that WPA is a useful tool that can help make strategic decisions to minimize water consumption and modify consumption patterns in industries, and by reducing effluent production environmental risks will be reduced.
期刊介绍:
Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
