<p>The Oxo Process that recycles its cobalt primarily as cobalt salt is improved by concentration of the cobalt salt solution from the demetalling section and the addition of a separation step for organic acid an water. This allows for a higher reuse of acid in the process and thus a lower amount of acid in the waste water. Injecting a higher concentration of cobalt salt solution to the reaction section also reduces the requirement for cobalt source.</p> |
