Abstract

Directional Solvent Extraction (DSE) is a system used to remove salts from brine water, utilizing organic solvents such as Diisopropylamine (DIPA); it is a well-studied system where the results obtained are promising because the removal of salts can be greater than 94%. The high demand of pure water for the oil and gas industry increases each year as access to fresh water is becoming complex and expensive. It is necessary to develop new technologies with higher recovery rates and environmentally friendly waste disposal. With a proposed semi-continuous system, divided into four stages, an analysis on retention times (RT), and a variation on the formulation for the brine water were conducted with a semi-continuous system and the results of this study showed the solvent performed better within a 24-hour of RT and the improvement of removing salts up to 98%, a recovery rate of 73% for TDS, and a 8% of water recovery rate with the possibility of incrementing due to the prospect of recirculation that the system offered.
