The reboilers used to be operated at 85 percent damper opening with stack temperatures of 280, 285 and 335 °C in the de-ethanizer, de-propanizer and de-butanizer reboilers respectively. A test conducted on these reboilers showed that 6.5 mm Btu/hr at a cost of about $260,000 per year can be saved if damper opening is adjusted to 70 percent.
