USE OF INFRARED SPECTROSCOPY TO PRODUCE HIGH LUBRICITY, HIGH STABILITY, FISCHER-TROPSCH DIESEL FUELS AND BLEND STOCKS

摘要

THE PRESENT INVENTION IS A METHOD FOR CONTROLLING A PROCESS FOR PRODUCING A DISTILLATE FUEL HEAVIER THAN GASOLINE. THE PROCESS INCLUDES SEVERAL DIFFERENT FRACTIONS (8, 11) STREAMS (8, 12, 15,17), INCLUDING ALCOHOLS, OLEFINS, AND ACIDS. AT LEAST ONE OF THE STREAMS (8) IRRADIATED WITH IR RADIATION, ALLOWING THE DETERMINATION OF THE CONCENTRATIONS OF AT LEAST ONE OF ALCOHOLS, OLEFINS AND ACIDS. THE TEMPERATURE OF THE SEPARATOR (6, 9) IS THEN ADJUSTED TO CHANGE THE CONCENTRATIONS TO PRE-DETERMINED VALUES. (FIGURE 1)
