Abstract
The present invention provides a new type of filtration system. Traditional designs required that personnel open the system to clean/change strainers while a process was in operation. This invention provides a straining system that allows process stream to be filtered in a manner completely internal to the process. The system includes dual strainers with a nitrogen purging system and solvent flush system. A creatively designed “catch” area is installed internal to the process to collect all solids that are flushed from the strainer system. The system remains completely closed for the duration of each production campaign, thus eliminating the safety hazard and labor requirement associated with opening a process system.
