Abstract
In at least one embodiment, a devolatilization vessel includes a first set of one or more devolatilization plates and a second set of one or more devolatilization plates. A first distributor is above the first set of one or more devolatilization plates and the second set of one or more devolatilization plates. A second distributor is above the second set of one or more devolatilization plates. In at least one embodiment, a process of forming a polymer includes forming a first polymer solution having a first viscosity and forming a second polymer solution having a second viscosity. The process includes flowing the first polymer solution and the second polymer solution to a devolatilization vessel. The process includes removing volatiles from the first polymer solution and the second polymer solution in the devolatilization vessel to form a devolatilized first polymer melt and a devolatilized second polymer melt.
