Abstract
A method for regulating use of stored diluent in a polymerization process so as to maximize use of diluent recycled diluent recovered from the process, and so minimize use of stored diluent, is disclosed. Also disclosed is apparatus, particularly as an arrangement of controllers and valves for handling the flow of diluent through the process that can be used to implement the disclosed process.
