“…Li salt concentrations in the produced water were enriched through the process of evaporation. Lithium precipitates at 80% when the evaporation reaches 40% in volume, which is similar to a literature review (Valdez et al, 2016). The crystal was collected in one beaker, designated for the subsequent process of lithium extraction.…”

During the last decade, the demand for lithium has been growing exponentially with its widespread uses in manufacturing, especially with the worldwide deployment of electric vehicles. Thus, lithium is considered integral to the U.S. economy, technological advancement, and the pursuit of sustainable and clean energy solutions. The produced water is known to be rich in several minerals and valuable elements, such as potassium and magnesium, and a trace amount of precious elements including lithium. However, the existence of metals in the produced water is one of the challenges to extract lithium, especially magnesium which is located in diagonal positions within the periodic table that exhibit similarities. The produced water was first purified, resulting in the complete removal of magnesium, and then lithium was precipitated by phosphate. The effects of operating conditions on the Li3PO4 precipitation behaviors were evaluated. The effect of different precipitating reagents was evaluated on the percentage of lithium extracted, Na3PO4 (TSP) was found to be a promising Li precipitating reagent. The highest percentage of lithium extracted was reached when the Li concentration of produced water was enriched and increased up to 350 mg/l, then Li removal was 53% at 7 grams of TSP and 200 rpm for 2 hours. The results indicated that temperature is a more important factor than stirring speed. The novelty of the current work is not only by the results obtained that may create additional financial benefits to oil-producing areas but on that the sustainable disposal of produced water may encourage the recycling and reuse practice, ultimately reducing the use of freshwater for hydraulic fracturing.

“…It is widely used in industrial applications, such as glass, ceramics, textiles, detergents, and nuclear power, as well as in the agricultural, medical, pharmaceutical and electronicsrelated sectors. Moreover, it is used as a raw material in the preparation of many boron chemicals, such as zinc borate, boron esters, boron carbide, boron nitrite, boron phosphate, boron trihalides, organic boron salts, and fluoroborates) (Valdez et al, 2014;Cavus and Kuslu, 2005;Mergen et al, 2003).…”

“…Depending on the reaction for talc synthesis, this concerns the recovery of either sodium acetate or sodium sulfate. Efficient and cheap precipitation of sodium acetate is likely possible following the procedure described in the paper by Liu et al, 41 while recovery of sodium sulfate could consider the procedure described in Valdez et al 42 Energy for pumping the solution and heated water into the supercritical hydrothermal reactor were calculated following recommendation in the literature and estimated at 3.2 kJ/kg of solution. 43 The data set for magnesium acetate was developed from the reaction of magnesium hydroxide with acetate.…”

Recent efforts in chemistry have led to development of a fast and continuous process for the production of synthetic talc in a supercritical hydrothermal reactor. This attractive process compatible with industrial requirements leads to advantageous physicochemical characteristics including submicrometer size, hydrophilicity, and high chemical and mineralogical purity. In addition, the high speed of the process and moderate reaction conditions have potential advantages from a viewpoint of the impacts on the environment. To verify environmental advantages and seize further opportunities to improve environmental performance, the current study evaluates the new process using the life cycle assessment (LCA) methodology. A cradle-to-gate assessment considers the production of synthetic talc from different magnesium and reagent acid precursors at different concentrations. The findings suggest high impacts of precursors (65−94%, depending on their concentration) and low impacts of process energy and water. Substituting magnesium acetate with magnesium sulfate could reduce greenhouse gases from 4.8 to 2.6 kgCO 2 and cumulative energy use from 86 to 34 MJ per 1 kg of synthetic talc. Discussion draws on previous LCA studies on the supercritical hydrothermal process and applications of synthetic talc considering its environmental performance and characteristics in comparison to the conventional (natural) talc.
