An overview guide that maps seven high temperature process units to the ceramic parts that wear in them, with pointers to the field data.
Seven process units, one turnaround window.
Which ceramic parts belong on the list?
This Blasch guide is an overview for turnaround planners in refining and chemical processing. It goes through seven high temperature units, names the typical wear and failure points in each and lists the ceramic parts that address them. It is a map, not a study: the guide itself carries almost no measured data, so this page links each unit to the papers in the library where the field results are published.
Most turnaround days are lost before the shutdown starts, when the parts that fail every campaign are not on the plan yet.
For each unit the guide lists failure modes such as thermal cycling, corrosion, erosion and uneven gas flow, and the parts that address them.
Flue gas tunnels, ferrules, burner nozzles, pilot and flare tips. Field data: StaBlox flue gas tunnel system.
Checkerwalls in the reaction furnace and ferrules in the waste heat boiler. Field data: PTQ checkerwall study.
Air grid nozzles, lined elbows, cyclone and scrubber linings. Product: FCC air grid nozzles.
Secondary reforming, GTL and syngas: round and hex ferrules for the waste heat boiler after the reformer.
Sulfuric acid: ferrules plus HexWall and VectorWall internals in sulfur burning and spent acid furnaces. The MECS Sulphur 2015 paper has the NOx and installation data.
Thermal oxidizers: ferrules and checkerwalls. A published incinerator case is summarized under SRU thermal incinerator.
Titanium dioxide: ferrules, vortex finders, valves, burner nozzles, lined elbows, spray nozzles, line chokes, reactor linings and bubble caps, and thermocouple protection tubes.
The guide reports that a US refinery presented results at the 2017 Brimstone Vail conference for a patented ferrule design developed with Blasch in 2005. The modified ferrule reduced peak heat flux at the tube inlet, which the operator linked to longer boiler tube life. The guide gives no figure. The background is on the page about ferrule design against film boiling.
Use it as a checklist for your turnaround scope. Where a part matters for your unit, ask for the data behind it, with plant type, medium and service period. The general claims in the guide on efficiency and energy savings are not quantified there, and this page does not repeat them.
Very little. It is an overview. Measured results sit in the published papers linked on this page.
No. Blasch makes cast ceramic parts such as tunnels, checkerwalls, ferrules, nozzles and liners. It does not coat.
The one whose ceramic part forces you to open the unit early. That part sets your campaign length.
Name the unit and the part. A Blasch engineer tells you what data exists for it and what it would take to change it.
