Pyrolysis of Naphtha and of Kerosene in the Kellogg Millisecond Furnace... 

Figure 1 shows the yields of principal products obtained from the steam pyrolysis of the naphtha feedstock as severity is varied, while contact times are maintained within 0.01 to 0.1 second. The open circular points are data obtained in the Kellogg Millisecond Pilot Plant, while the closed points are data obtained in the Millisecond Bench Scale Unit, and the square points are the data observed with the commercial Millisecond Furnace at Tokuyama ( ). These data clearly establish that excellent correspondence exists between the experimental results from these units. The observed agreement is even more remarkable when one considers that the scale-up factors between the bench scale-pilot plant and the pilot plant-commercial furnace are of the order of 10 and 10, respectively. 

However in the 1980 s, the latest furnace designs offered times ranging from 0.2-0.08 s. Millisecond technology, developed by Kellogg Co and industrialized by Idemitsu Petrochemical Company at their Chiba factory in 1985 is operating at the lowest end of that range. 

Working in close cooperation with Idemitsu Petrochemical Company, Kellogg designed a prototype of the Millisecond Furnace with a nominal ethylene capacity 25,000 metric tons a year. This furnace, shown in Figure 6, also served as an expansion to Idemitsu s No. 2 Ethylene Plant at Tokuyama, Japan.
