Deactivation of hydrogen generation unit catalyst is linked to contamination of boiler feedwater from a leaking heat exchanger
A new hydrogen-generation unit (HGU) began experiencing deactivity of the reformer catalyst early in its service life. Refinery engineers suspected that coke formation on the catalyst was the root cause for the problem. Further investigation determined that a leak in a heat exchanger in the sour-water unit was the culprit. The following case history shows how a condensate leak deactivated catalyst of the hydrogen reformer. In this case, the poisoning of the catalyst was very similar to the same processing effects from sulfur contamination from natural gas (NG) in the hydrogen reformer.
Need for more hydrogen. Globally, the sulfur content of saleable diesel grades is decreasing.1 In addi
