Publication number: 20230374166Abstract: A purge system for a polymerization system may include a purge column including a stripping zone and a stripping fluid distributor below the stripping zone for injecting a stripping fluid including one or more light olefins. A first displacement zone is below the distributor. A second displacement zone is below the first displacement zone. A nitrogen distributor introduces nitrogen in the second displacement zone. Another purge system for a polymerization system may include a fluidized bed separator and a purge column. The fluidized bed separator includes a separator inlet, a stripping fluid inlet, a first stripped fluid outlet, and a separator outlet. The purge column includes a flake inlet, a stripping zone, a stripping fluid distributor below the stripping zone, a stripped flake outlet, and a second stripped fluid outlet for a second stripped fluid from the purge column.Type: ApplicationFiled: May 20, 2022Publication date: November 23, 2023Applicant: CHEVRON PHILLIPS CHEMICAL COMPANY LPInventors: Kenneth A.
