Lithium Hydroxide

Peter Ehren's first involvement with lithium hydroxide was intensive testing of lithium chloride electrolysis. He was closely involved in the testing, design, engineering, and operation of the first lithium hydroxide plant of SQM using lime and lithium carbonate. PEC delivered the design for the lithium hydroxide plant for Arcadium Lithium plant in Japan. Intensive testing was done with GEA and Veolia. PEC invented and patented the production of lithium hydroxide directly from lithium chloride and lithium nitrate by using potassium hydroxide known as Lithium Ark and Blue refineries.
