During the 1950's, the expander turbine was the leading in its industry.The Elliott power recovery expander turbine was innovated into a high temperature but with a low temperature flue gas energy into usable power. This expander turbine is usually used to drive compressors or generators in refinery fluid catalytic-cracking (FCC) service. The recovery power that these expander turbines are capable of is reaching up to the approach of 50,000 hp or 37,300 kW.
The designs of Elliott engineers are growing and still innovating that results to the advancement of expander technologies. Through those innovations, Elliott expander turbines was able to meet the changing demands of the FCC process. With the use of fluid dynamics, Elliott expander was able to extend typical time between turnarounds in the industry average.
