| Popis: | In oil refining industries there is a high water consumption, which influences the high production costs and impacts the environment due to the discharge of their wastes. It is known that there are no technological conditions for the reuse of industrial water at the oil refineries, based on hydroskimming processes. The objective of this study is to implement the process integration methodology, Water Pinch, to a sour water stripper unit, as a unitary process of an oil refinery, to minimize the amount of sulphurous waste water and reduce contamination of the bay that receives these wastes. The technology is applied to evaluate the volume of sulphurous wastewater generated in the Cienfuegos oil refinery. This technology allows identifying opportunities for recovery and reuse of water, based on concentration ranges of contaminants. To achieve this purpose, a sour water stripper tower was assessed with the help of Water Pinch software, which provided an optimized distribution network, as a proposed technological improvement. This facilitated to recover and reuse 667 757, 28 m3 of water per year, and 1 035 023, 78 CUC were saved, at the same time the amount of polluting effluents decreased in approximately 2 % of non-reusable treated water. |
