Abstract

The invention provides a process and a plant for reducing cobalt content contained in Low Temperature Fisher-Tropsch process water. The process includes the steps of: adding a hydroxide salt or solution to the Low Temperature Fisher-Tropsch process water to form cobalt hydroxide precipitate; allowing the hydroxide precipitate to settle; and separating the supernatant with reduced cobalt from the precipitate.
