Oilfield brine extracted with hydrocarbons is often considered as a problematic waste. The typical management option for this produced water is reinjection into the formation to maintain the reservoir pressure (or just for disposal). High salinity of produced water is on the one hand a drawback, but on the other hand an advantage because it can be used as a raw material for the production of valuable chemicals. In this paper a freezing-thawing desalination method was tested to obtain partially desalted water and c...

With the continuous technological advancement the global demand for selected chemical elements in both emerging and established solutions is rising. This is particularly evident in energy storage applications, such as lithium-ion batteries for increasingly popular electric vehicles. The growing need for lithium carbonate drives the search for innovative extraction methods, including recovery from brine through chemical processes. This approach not only aids in lithium recovery but also positively impacts the envir...
