Product Description
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Stauffer Chemical Company operated contact-process sulfuric acid plants that used asbestos-refractory converter linings, asbestos-block hot-side lagging on the multi-pass vanadium-catalyst SO2 / SO3 converter vessels, asbestos-block lagging on interpass heat exchangers and superheaters, and asbestos-packed flange gaskets on hot acid and gas piping. According to those publicly filed asbestos litigation records, the asbestos-refractory converter lining allegedly protected the vessel shell from hot SO3 gas, and the asbestos-block hot-side lagging allegedly held skin temperatures down on the converter and heat-exchanger shells.
Plaintiffs alleged that Stauffer sulfuric acid converters required periodic vanadium-catalyst screening and re-charging, during which the asbestos-refractory converter internals were allegedly disturbed and asbestos-block lagging was allegedly stripped and replaced.
