[ That which is claimed is:] [1.] A process comprising:(1) producing a First Stream in a First Source Zone;wherein said First Stream comprises polymer, diluent, and other compounds;wherein said First Source Zone is a zone where said First Stream is produced using slurry polymerization conditions;(2) transporting said First Stream from said First Source Zone through a First Stream Zone and to a First Separating Zone;(3) separating, in said First Separating Zone, said First Stream into a Second Stream and a Third Stream;wherein said Second Stream comprises a major part of the vapor phase of said First Stream;wherein said Third Stream comprises a major part of the solid and liquid phases of said First Stream;(4) transporting said Second Stream from said First Separating Zone through a Second Stream Zone and to Second Cooling Zone;(5) transporting said Third Stream from said First Separating Zone through a Third Stream Zone and to a Second Separating Zone;(6) separating, in said Second Separating Zone, said Third Stream into a Fourth Stream and a Fifth Stream;wherein said Fourth Stream comprises a major part of the vapor phase of said Third Stream;wherein said Fifth Stream comprises a major part of the solid phase of said Third Stream;(8) transporting said Fifth Stream from said Second Separating Zone through a Fifth Stream Zone and to a First Collecting Zone;(20) cooling, in said Second Cooling Zone, said Second Stream to produce a Twelfth Stream;(21) transporting said Twelfth Stream from said Second Cooling Zone through a Twelfth Stream Zone and to a Fourth Separating Zone;(22) separating, in said Fourth Separating Zone, said Twelfth Stream into a Thirteenth Stream and a Fourteenth Stream;wherein said Thirteenth Stream comprises a major part of the liquid phase of said Twelfth Stream;wherein said Fourteenth Stream comprises a major part of the vapor phase of said Twelfth Stream;(23) transporting said Fourteenth Stream from said Fourth Separating Zone through a Fourteenth Stream Zone and to a Third Cooling Zone;(24) transporting said Thirteenth Stream from said Fourth Separating Zone through a Thirteenth Stream Zone and to a Third Collecting Zone;(25) cooling, in said Third Cooling Zone, said Fourteenth Stream to produce a Fifteenth Stream;(26) transporting said Fifteenth Stream from said Third Cooling Zone through a Fifteenth Stream Zone and to a Fifth Separating Zone;(27) separating, in said Fifth Separating Zone, said Fifteenth Stream into a Sixteenth Stream and a Seventeenth Stream;wherein said Sixteenth Stream comprises a major part of the liquid phase of said Fifteenth Stream;wherein said Seventeenth Stream comprises a major part of the vapor phase of said Fifteenth Stream;(28) transporting said Seventeenth Stream from said Fifth Separating Zone through a Seventeenth Stream Zone and to a Fifth Collecting Zone; and(29) transporting said Sixteenth Stream from said Fifth Separating Zone through a Sixteenth Stream Zone and to a Fourth Collecting Zone.
