Latest Patents

Among his latest patents, Sugita has developed a method for reducing coking in the FCCU feed zone. This method predicts the tendency of a heavy oil feed to generate coke deposits in the FCC riser under specific operating parameters. By utilizing appropriate operating parameters, the formation of coke deposits can be minimized. The method involves establishing a margin between the theoretical dew point of the hydrocarbon feed and the theoretical mix zone temperature in the feed injection zone. This margin is derived from a regression-based linear model, allowing for the operation of the mix zone at a temperature that reduces riser coking to acceptable levels.

Another significant patent by Sugita focuses on optimizing catalyst/oil mixing in an FCC reactor feed zone. This method enhances the uniformity of the contact between heavy oil feed and FCC cracking catalyst. By injecting the heavy oil feed into the catalyst through strategically located feed injectors, the method minimizes temperature profile differences across the oil/catalyst mixture, thereby improving the efficiency of the cracking process.
