Hydrogen-Starved Unit Struggles To Make ULSD

Hydrogen-Starved Unit Struggles To Make ULSD

This is a 36 bar (525 psig) unit that was converted to ulsd service. The first two cycles used Albemarle KF-757 and lasted 6 months compared to one year expected cycle life. They switched to Topsoe catalyst for the next cycle and saw no improvement.

Two suppliers recommended replacing the reactor internals; but Johnson Matthey did a convincing analysis showing the unit was constrained by hydrogen supply, not flow distribution, and new internals would not fix the root cause of their short cycles......

Ambient Conditions Impact CO and NOx Emissions: Part 1

Ambient Conditions Impact CO and NOx Emissions: Part 1

Changing ambient conditions can impact CO and NOx emissions without proper process adjustments. A wide range of operating conditions show how these emissions can be affected by ambient condition changes for fuel gas-fired natural draft process heaters.

Since process heaters are typically located outside, their operation is subject to the weather. Heaters are usually tuned to a given set of conditions. However, the actual operating conditions can vary dramatically from season to season and sometimes even during a day. Wind, ambient air temperature, ambient air humidity and atmospheric pressure can all significantly......
