Product Description

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that W.R. Grace & Co., through its Davison Chemical Division, operated fluid catalytic cracking (FCC) catalyst manufacturing plants at Curtis Bay MD and Lake Charles LA that used asbestos-woven fabric outer lagging on fluid-bed reactor and spray-dryer shells, asbestos-refractory hot-side lining on catalyst calciners and spray-dryers, and asbestos-packed flange gaskets on hot catalyst-transfer piping. According to those publicly filed asbestos litigation records, the asbestos-fabric lagging allegedly held skin temperatures down on the fluid-bed vessels, and the asbestos-refractory lining allegedly protected the vessel shells from hot catalyst service.

Plaintiffs alleged that Davison FCC catalyst plants required periodic refractory patch on calciners and spray-dryers, and that asbestos-fabric lagging on the fluid-bed reactor shells was allegedly stripped and re-lagged during scheduled turnarounds.
