Title:
HYDROGEN SULFIDE PURIFICATION METHOD AND LITHIUM SULFIDE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/034533
Kind Code:
A1
Abstract:
Provided is a hydrogen sulfide purification method in which, in a process for producing lithium sulfate by the reaction of hydrogen sulfate with a lithium raw material, the lithium raw material is removed from a mixed gas (101) containing an unreacted portion of hydrogen sulfide and an unreacted portion of the lithium raw material which is generated in the process by using an ejector that utilizes a washing solution as a driving fluid.
