The Powder Discharge System Process
The production of polyethylene and polypropylene is a licensed process. Within this process, powder is created in a reactor with the addition of a catalyst. This powder is discharged from the reactor for further processing and pelletizing for downstream use. It is during this powder discharge system (PDS) phase that producers face significant challenges in their valve reliability, and ultimately, the productivity of their operations. These process challenges, illustrated in detail below, require superior valve technology to advance producers’ quality and efficiency goals. The blue colored valve icons in the process map below indicate the critical service valves that require priority attention.
