USE OF OXYGEN ANALYSIS BY GC-AED FOR CONTROL OF FISCHER-TROPSCH PROCESS AND PRODUCT BLENDING

Title:

USE OF OXYGEN ANALYSIS BY GC-AED FOR CONTROL OF FISCHER-TROPSCH PROCESS AND PRODUCT BLENDING

Document Type and Number:

WIPO Patent Application WO2003060040

Kind Code:

A3

Abstract:

Methods for producing a substantially paraffinic Fischer-Tropsch product or a blended Fischer Tropsch product comprising a selected oxygenate concentration, and if required, a selected oxygenate concentration of specific individual oxygenates, are disclosed. The methods of the present invention measure oxygenate concentration using GC-AED. The oxygenate measurements obtained using the GC-AED may be used to adjust and control various processes used to produce, upgrade, or finish Fischer Tropsch products to provide Fischer Tropsch products with a selected oxygenate concentration, and if required, a selected oxygenate concentration of specific individual oxygenates.
