Metals are permanent poisons for the naphtha reforming catalysts and irreversibly damage the catalyst. Most metals poison the metal functions of the catalyst. Metals impact tends to progress sequentially through
The acidity of the naphtha reforming catalyst is controlled by the moisture in the feed and the chloride level on the catalyst. An increase in the feed moisture will strip
Sulfur is the most common impurity present in the feed of the naphtha reforming unit. The maximum allowable concentration is nearly 0.5 weight ppm expressed as S. Sulfur is poison
Nitrogen is a temporary acid function poison of naphtha reforming Platinum catalyst. Reformer feed nitrogen is normally controlled at 0.1~0.5 wppm and is less frequently present in the reforming feed.
The main purpose of the catalytic naphtha reforming process is to increase the octane number of heavy naphtha and to produce large quantities of hydrogen. The reforming process and expected
Catalytic reforming catalysts are bifunctional, with the metal and acid sites assumed to be in some “balance” that enables total and effective utilization of the metal and acid sites. Metal-acid
The major process variables that affect the performance of the catalytic naphtha reforming or platforming unit are reactor pressure, reactor temperature, space velocity, hydrogen to hydrocarbon (H2/HC) molar ratio, feedstock
A HAZOP team facilitator is a key person in conducting a successful and effective hazard and operability (HAZOP) study. A HAZOP team facilitator is responsible for leading and managing the
Node selection is a critical early step in a HAZOP study because it directly determines study duration, schedule accuracy, and workshop effectiveness. The number, size, and complexity of nodes provide
