Applications

GEOLITH process solutions apply to installations treating water or brine naturally charged with lithium (deep geothermal water, oil waters and salt brines). Our Li-Mag process is specific to the purification of the lithium brines produced on existing salars, which allows up to double the production. Our Li-Capt process aims to extract lithium directly from the brine, even at low concentrations (50 to 500 mg / l) while guaranteeing profitable exploitation.

 

1. Deep geothermal energy

The water flowing through deep geothermal plants at high flow rates can be so concentrated that the lithium requirements for 20 to 100,000 electric vehicles per year can be met from a single plant.

 

2. Oil production waters

The water extracted with petroleum from current wells is also often loaded with lithium. With a very large number of wells in service, the resources are considerable.

 

3. The salars

Many salars are not exploited because the conditions for economic operations are not met with current natural evaporation processes.

 

GEOLITH solutions are aimed at any type of fluid containing lithium

 

 

In 2019, GEOLITH obtained the support of ADEME (French Environment and Energy Management Agency) for its Li-Capt R&D program in collaboration with MinesParisTech. Within this framework, GEOLITH has built a pilot demonstrator which operates for tests in Alsace at the heart of deep geothermal installations. This pilot is a mobile equipment which allows GEOLITH to offer it for rent with tests on different customer sites since early 2021. 

This phase is essential to analyse the performance of the GEOLITH solution in-situ and to collect the data necessary to study the final industrial installation.

Installed on the geothermal site and connected directly to the reinjection circuit, the GEOLITH pilot  operates in real operating conditions (up to 70°C and 36 bars).

The tests carried out enable process parameters in order to optimize future industrial plant.
