ELECTROLYSIS PLANT AND METHOD FOR TREATING CELL GASES

摘要

The invention relates to a plant (1000) comprising a series of cells (2) and a circuit for treating gases produced in the cells (2), which treatment circuit has a first treatment stage (100) for treating hydrogen fluoride, a second treatment stage (102) for treating sulphur dioxide, and an alumina supply circuit for supplying the first treatment stage (100) and the second treatment stage (102) with alumina. The plant (1000) further comprises a heat exchanger (142) positioned between the first treatment stage and the second treatment stage.
