Plant notes
Reactor baskets, quench internals, and outlet collectors specified against a heavier sour naphtha slate heading into gasoline blending.
Reactor baskets, quench internals, and outlet collectors were released against a heavier sour naphtha slate heading into gasoline blending. The production risk was sulfur slipping into the reformer and into finished gasoline together.
The package is one mechanical file: internals, pressure drop, and recycle-gas duty written so the compressor still holds when the feed darkens. Drawings and inspection points went to the fabricator with the same metallurgy the wet H2S service needs.
A coastal plant asked for tighter vapor recovery tie-ins so blending tanks stay inside the fence-line permit during summer RVP swings.
A coastal plant asked for tighter vapor recovery tie-ins so blending tanks stay inside the fence-line permit during summer RVP swings. Light ends that flash in July change both the lab sheet and the flare log.
We resized header takeoffs and knockout duty against fill rates the blender actually uses. The production side keeps a summer blend; the permit side keeps a reading that is a routine check, not a shutdown.
Assay work on blended crudes to keep the naphtha cut stable enough for downstream reforming without a full column replacement.
Assay work on blended crudes was run to keep the naphtha cut stable enough for downstream reforming without a full column replacement. The question was production rate on a heavier slate, not a new nameplate.
Cut points, pumparound duty, and overhead chloride risk were checked against the worst blend in the slate. The recommendation was internals and heat, not a new tower, so gasoline reforming still sees a naphtha it can finish.
Revamped internals and pumparound exchangers restored a naphtha endpoint the reformer can finish on a heavier slate.
The coastal atmospheric unit came back from turnaround with new trays and selected pumparound exchangers. The naphtha endpoint is again inside the window treating and reforming were designed for, on a heavier crude than the original internals allowed.
This is the production slice of a wider site program. Tankage and docks stayed with other contractors. Our file was the column internals and the rundown exchangers that decide whether the cut is gasoline feedstock or rework.
Heater tubes and pass arrangement checked so catalytic reforming can still make octane barrels when naphtha endpoint moves.
Charge-heater tubes and pass arrangement were audited so catalytic reforming can still make octane barrels when the naphtha endpoint moves. A heater that cannot follow the cut forces the blender to buy octane the unit was supposed to produce.
Tube metal, flux, and fuel-gas quality were checked together. The note to operations is practical: which passes to watch, and which spare tubes to hold, before summer gasoline blending starts pulling octane.
