ABSTRACT:
A process for treating nitrogen-containing, substantially paraffinic product derived from a Fischer-Tropsch process. The substantially paraffinic product is purified in a purification process to lower the concentration of oxygen, nitrogen, and other impurities. The nitrogen content of the purified product is monitored, and the conditions of the purification step are adjusted to increase nitrogen removal if the nitrogen content of the purified product exceeds a preselected value.
