Breakthrough in lithium extraction test in southwest oil and gas field

　　A few days ago, 100 grams of lithium hydroxide was obtained from the gas field water of the Longwangmiao Formation gas reservoir of PetroChina Southwest Oil and Gas Field Company, and 400 grams of lithium carbonate powder was extracted
.
This is the first time in the domestic oil and gas field industry to extract lithium from gas field water, achieving a "zero breakthrough"
.

　　The traditional lithium extraction process from brine is only for salt lake brine, and lithium extraction from gas field water is still in the exploratory stage
.
Preliminary screening shows that the Longwangmiao Formation gas reservoir has relatively rich lithium reserves, so the exploration of lithium extraction from gas field water is imperative
.

　　Since the beginning of this year, Southwest Oil and Gas Field has cooperated with Southwest Petroleum University and Chengdu Jinli New Energy Technology Co.
, Ltd.
to overcome difficulties such as limited space in the pilot experimental site and complicated water quality pretreatment.
At the end of June and the beginning of July, the extraction of 40 liters was successfully achieved.
High-concentration lithium chloride solution to obtain 100 grams of lithium hydroxide, and extract 400 grams of lithium carbonate powder
.

　　The pilot test of lithium extraction from gas field water associated resources in the Longwangmiao Formation gas reservoir not only extracts lithium from gas field water for the first time, but also verifies the feasibility of the "pretreatment + lithium extraction cabin" method of "pretreatment + lithium extraction shelter" from the industrial point of view.
, laying the foundation for further promotion
