Abstract
An integrated Fischer-Tropsch process provides methods for recovering reaction water from a Fischer-Tropsch reactor with minimal adverse environmental effects and with reduced costs compared to traditional methods. Reaction water, preferably separated from an overhead stream from a Fischer-Tropsch reactor, is vaporized and contaminants are thermally oxidized while in the vapor state. The thermal oxidation also produces flue gases, which flue gases may be condensed to recover water.
Claims20
A Fischer-Tropsch process which comprises:
- a) recovering reaction water from a stream from a Fischer-Tropsch reactor;
- b) indirectly heat exchanging the reaction water using energy from the Fischer-Tropsch process to vaporize the reaction water, producing a heat-exchanged reaction water;
- and
- c) reacting the heat-exchanged reaction water in a thermal oxidizer, producing flue gas.
