Abstract:
1. A method for reducing intermediate processing steps for making PET objects comprising: reacting a first PET precursor and a second PET precursor to produce a PET melt in a reactor; flowing said PET melt to a valve having at least two outlets; flowing said PET melt from at least one of said at least two outlets to at least one distribution manifold, each of said at least one distribution manifold having at least two distribution lines; controlling the residence time in each of the at least two distribution lines for controlling the acetaldehyde content in said PET melt, providing a first pump configured to control the residence time, the first pump located between the valve and the reactor; controlling individually the mass flow of the PET melt in each of said at least two distribution lines independently of the other of said at least two distribution lines; providing a second and third pump, the second and third pump configured to control the residence time in each of the at least two distribution lines, the second pump located between the at least one distribution manifold and a first forming die, the third pump located between the at least one distribution manifold and a second forming die; controlling a first speed of the first pump responsive to a first and second pressure at the second and third pump respectively; and forming said PET objects from said PET melt with the first and second forming die.
