Our client was seeking to improve its production efficiency by introducing a solvent refining method to recapture materials critical for producing lithium batteries.
The demand for lithium has significantly increased in the last few years due to a spike in the market for electric vehicles, which also compete with laptops and smartphones for lithium ion batteries. During the process of refining lithium for use in lithium batteries, a considerable amount of material is lost within the solvent used to coat the cathode materials during the production process. By reclaiming and refining degraded solvent, our client was able reduce waste of rare and costly chemical compounds to significantly reduce overall refining costs.
McKenna Engineering designed and built a closed loop refining heat pump uniquely utilizing water (R-718) as refrigerant. Additionally, the rejected heat was added back in as heat addition to maximize the solvent refining efficiency.
The system was delivered completely pre-piped, pre-wired to a complete starter/control panel, and pre-tested (functional test at Mckenna Engineering’s facility in Carson, CA) ready for installation at the job site.
